GB2RS News Sunday, the 15th of June 2025 The news headlines: Book now to secure your place at the RSGB 2025 Convention The RSGB launches the “SES Cookbook” The RSGB Operating Advisory Service issues advice The RSGB annual Convention is a fantastic opportunity for radio amateurs to meet, learn and share experiences. Whether you're newly licensed or have years of experience, there is always more to discover. That's why the Society is excited to introduce this year's theme: “Discover, Learn, Progress”. Whether you want to discover something new, learn more about a particular aspect of amateur radio, or progress and develop your skills, you'll find something at the Convention to explore and enjoy. The prestigious event will take place between October 10th and 12th at Kents Hill Conference Centre in Milton Keynes. Book now to secure your place in joining like-minded people for what is also one of the best social events in amateur radio. Take advantage of the early-bird prices by going to rsgb.org/convention. The Society is delighted that the event will be sponsored again by Martin Lynch and Sons. Special event stations are popular around the world and a great source of fun and excitement for organisers and QSO chasers. They can also be a fantastic tool for outreach, allowing you to demonstrate amateur radio and encourage people to find out more. But how do you organise an event to achieve all those objectives? The RSGB has just launched a new web section that focuses on special event stations. For RSGB members and Affiliated Clubs, there is an online guide called the SES Cookbook, which offers a wide range of practical guidance to help you deliver the best experience for your visitors and the organisers. The guide covers a wide range of topics, including how to apply for a special event station callsign, the stages of the planning process, publicising your event to attract visitors and how to make a good number of contacts. For non-RSGB members, there is a simple guidance document that outlines the main things to consider when planning this type of event. The new section also draws together existing information about permanent special event stations as well as QSL guidance. If you're planning an event for this year, or even for next year, now is the time to make the most of this comprehensive guide. Go to rsgb.org/ses  to find out more. The RSGB Operating Advisory Service, or OAS, provides advice to members on dealing with situations that are not within the spirit of amateur radio. From time to time, this activity goes beyond what is classed as acceptable behaviour and requires action to be taken. In these circumstances, the OAS recommends reporting the matter directly to Ofcom and to the police in the case of issues which could be classed as harassment, stalking or hate crimes. Experience has shown that this carries more weight coming directly from the people hearing or suffering the problem rather than a third party, such as the RSGB. If you hear anything that is not acceptable behaviour, contact the RSGB OAS first, and the team will suggest the correct course of action. Once Ofcom and the police have issued reference numbers, these should be passed to the Operating Advisory Service. You can contact OAS via oas@rsgb.org.uk The RSGB has submitted responses to a pair of Ofcom consultations. The first considered a series of licence exemption updates, including arrangements for some visiting radio amateurs to the UK. The second concerned filing procedures for the growing number and variety of satellites. Both replies were developed by the RSGB Spectrum Forum, drawing on its members' wide breadth of expertise. The Spectrum Forum expects that there will be further updates to both topics. Find the full replies by going to rsgb.org/spectrumforum  and selecting the ‘Papers and Consultations' option from the right-hand menu. The RSGB recently announced two new volunteering opportunities. The RSGB CW Champion will help the Society in taking Morse code to new audiences. Tasks will vary from developing the CW content on the RSGB's website through to developing and supporting a team of enthusiastic individuals who can support CW-related activities. The second role requires an individual with experience in science, technology, engineering and mathematics. The RSGB STEM Champion will help the Society to reach new audiences, build relationships with related organisations and encourage more young people into STEM careers. Go to rsgb.org/volunteers  to read the full role descriptions and learn how to apply.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 12th of June 2025 Propagation was a mixed bag last week, with occasional Kp index rises but a solid solar flux index, which hit 141 on Thursday, the 12th. We also had some sporadic-E short-skip conditions on the HF bands, which brought some surprises. We are now in June, so the summer HF doldrums are well underway. But that doesn't mean that the fun has gone from the HF bands. Daytime maximum usable frequencies over a 3,000km path have been around 18 to 20 MHz, so the main active band has been 20m. Paul, GM4ULS, reports that there was a spectacular inter-G event on the morning of Tuesday, the 10th of June. Whilst activating special event station GB70RS from Perth, he worked a mini pile-up of English stations from anywhere between Southampton and Manchester. This was between 0949 and 1022 UTC on 14.210 MHz. He said it sounded like the 40m band at times! We think this was probably a Sporadic-E event, which often creates strong but short-lived paths across the UK on the HF bands in the summer. We normally think of Sporadic-E as affecting the 10m band, but the lower bands are also often implicated. Have you worked anything unusual via Sporadic-E? If you have, please send your reports to radcom@rsgb.org.uk Otherwise, DX on the HF bands has been a little sparse, with paths opening to South Africa and South America on the 20 and 17m bands at times. Perhaps this is a good time to work some Summits on the Air or World Wide Flora and Fauna stations in Europe. These are usually QRP stations that appreciate your contacts. Next week, NOAA predicts the solar flux index will be in the 120 to 130 range. Unfortunately, geomagnetic conditions are predicted to be unsettled, thanks mainly to the return of a massive coronal hole on the Sun. Disruption was due to start around the 14th, but due to the hole's size, this could continue for at least three days with a maximum Kp index of 6. Expect the HF bands to be disrupted with lower maximum usable frequencies as the plasma in the solar wind hits the Earth. It may be a good time for visible aurora hunting, though. And now the VHF and up propagation news from G3YLA and G4BAO The high summer conditions have brought an increasing chance of Sporadic-E, particularly on digital modes, with DXmaps.com  plots showing plenty of paths on most days. Many of these are possibly associated with turbulence generated by jet streams in the weather part of the atmosphere. These send atmospheric gravity waves upwards to affect the E region. It's this association with specific weather features that makes Sporadic-E sporadic in a geographical sense. If so, in the coming week, the jet streams are mainly over the northern fringe of Europe. These suggest a better chance of paths to Scandinavia with fewer options to the south to support paths to the Mediterranean and the Balkans. In any event, June is high season for Sporadic-E, so remember to check the 6m band either mid-morning or late afternoon. The early thundery weather at the end of last week was useful for rain scatter on the GHz bands, and it is just possible it will return for the end of the coming week. In between times, it will be a high-pressure story that will dominate and may well produce some useful Tropo conditions. However, note that in the hot days of summer, inversion conditions and Tropo will be better at night and tend to weaken by the middle of the morning. Meteor scatter will have been boosted by two showers on the 7th and 8th of June, and, since they were broad peaks, there should be some meteor input left to see us through the coming week. For EME, sky noise is dropping. Low declination is now starting to decrease. So, Moon windows and peak elevation are improving. EME conditions are classed as poor to moderate today, the 15th of June, but are then good on the 21st and 22nd of June. And that's all from the propagation team this week.

This week's EYE ON NPI is a super connector - it's the Texas Instruments SimpleLink Wi-Fi CC33xx Family (https://www.digikey.com/en/product-highlight/t/texas-instruments/simplelink-wi-fi-cc33xx-family) with 2.4GHz and 5GHz WiFi 6 support, plus optional Bluetooth LE, in a low cost co-processor you can add to any microcontroller project you have to instantly IoT-ify it. This family of chips is a big upgrade in the CC3 family, and looks like a very competitive solution to existing market chips - we're excited to see how TI has adapted to the existing market to bring this compelling offering. Oh the TI CC3x series, how you've grown! We first met you back when it was the CC3000, a radical WiFi co-processor with the (at-the-time) astonishing price of ~$10 per module. At the time, we crafted an Arduino-compatible shield and a breakout board (https://learn.adafruit.com/adafruit-cc3000-wifi/overview) as well as an Arduino port of the TCP/IP mini-stack so that folks could do amazing things like get the time (https://learn.adafruit.com/adafruit-cc3000-wifi/internettime), read a web page (https://learn.adafruit.com/adafruit-cc3000-wifi/webclient) or even send a Tweet (https://learn.adafruit.com/adafruit-cc3000-wifi/sendtweet). The big thing was making it so you weren't spending the $50 it cost up-till-then to add a full-linux-system-as-peripheral (https://www.adafruit.com/product/1498). Since then, TI has released some updated versions, such as the CC3100 (https://www.digikey.com/short/9cp431pr), which added 802.11n and lower power draw - we saw it featured in a few micropython projects (https://blog.adafruit.com/2016/08/24/micropython-name-badge-from-emf-2016/) thanks to the core driver support (https://github.com/micropython/micropython/tree/master/drivers/cc3100). And after that, the CC3200 series (https://www.digikey.com/short/9289jcq3), which added TLS/SSL support and had an internal ARM Cortex-M4 that could run code on its own, like MicroPython! (https://github.com/micropython/micropython/blob/master/ports/cc3200/README.md) So it's no surprise that TI is continuing to press their WiFi family forward, to now the CC33xx! The new Texas Instruments SimpleLink Wi-Fi CC33xx Family (https://www.digikey.com/en/product-highlight/t/texas-instruments/simplelink-wi-fi-cc33xx-family) comes with 4 variants: the CC330x have 2.4GHz WiFi only, where-as the CC335x add 5GHz for an additional cost. Likewise, the CC33x0 have only WiFi, and the CC33x1 have WiFi+BLE. Since all the chips / modules are pin-compatible, you can develop with one and then change in production to whatever final setup suits your product. Like the earlier chips, these chips are expected to be connected to a main processor: either a microcontroller or microcomputer, over SPI or SDIO. SPI will work great for your smaller micros, SDIO is great when you have the speed and bandwidth to shift a lot more data around. When connecting over BLE, use the UART-with-flow control - that's the standard for a "BTLE Host Controller Interface" communications (https://www.bluetooth.com/wp-content/uploads/Files/Specification/HTML/Core-60/out/en/host-controller-interface/uart-transport-layer.html). Of course, there's no way you'll want to write a driver for this kind of complex chip - so visit the CC33xx software download page (https://www.ti.com/tool/CC33XX-SOFTWARE) which has software in the form of Linux kernel patch/drivers for beefy chips, or an microcontroller with an RTOS - follow their porting guide to get it running on a non-TI chipset (https://dev.ti.com/tirex/explore/node?node=A__AEIJm0rwIeU.2P1OBWwlaA__CC33XX-RTOS-MCU__dzPVh4K__LATEST) Now you're probably saying "OK cool but I don't want to do a bunch of RF layout, I want a nice tinned module i can slap down and connect my RP-SMA or chip antenna" - and not surprisingly, it looks like there's a CC3301 module (https://www.ti.com/product/CC3301MOD) in pre-production with an optimistic budgetary price of $2.88 - that's for 2.4GHz + BLE. For the 5GHz CC3351MOD (https://www.ti.com/product/CC3351MOD) the price is $3.50. Sans BLE the CC3350MOD (https://www.ti.com/product/CC3350MOD) is $3.13. If you want a peek at what the CC3301 module might look like, the BoosterPack product page has a tantalizing glimpse (https://www.ti.com/tool/BP-CC3301MOD). You can sign up at TI's site for updates on the release schedule, or chat with your DigiKey sales rep and they'll let you know when the part makes it into general distribution. Until then, you can get plenty of TI CC3350 (https://www.digikey.com/short/3z7tqtrp) and CC3351 (https://www.digikey.com/short/hmqzwv5j) bare chips: they're both in stock at DigiKey for immediate shipment! Order today and you'll quickly add low-cost WiFi 6 + BLE support to your next design, with 2.4/5 GHz support so you're ready for any customer or configuration. With ready-to-go software, and great low prices, you can get your design set up with cutting-edge networking without breaking the BOM bank.

GB2RS News Sunday, the 8th of June 2025   The news headlines: The RSGB releases a video to celebrate Volunteers' Week Get involved with the GR2HQ contest challenge Join the RSGB Regional Team   As Volunteers' Week comes to a close, the RSGB would like to thank its volunteers once again for all they do. As part of the week-long event, the Society released a video about the volunteer team at the RSGB National Radio Centre. These volunteers welcome over 80,000 visitors to the Centre every year and share amateur radio with them. Watch the video to discover the variety of things that they do as well as what they enjoy most about their role.

Using AM, FM, SSB and CW on the 2m band, the exchange is signal report, serial number and locator. Note that 5W is the maximum power allowed in this contest. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 5th of June Last week's HF propagation was heavily influenced by unsettled geomagnetic conditions. This was caused by a combination of coronal mass ejections and a strong solar wind from a coronal hole. The coronal mass ejection, or CME for short, followed a solar flare from sunspot 4100 on the 31st of May at 0005 UTC. The explosion lasted more than three hours. Type 2 radio emissions from shock waves within the CME cloud suggested it was travelling at 1,938 kilometres per second, or 4.3 million miles per hour! Eventually, the Bz swung south. This meant that the interplanetary magnetic field more easily coupled with the Earth's magnetic field. The result was that the Kp index got up to 7.67 on the 1st of June. The auroral effects were reported as being due to a co-rotating interaction region, or CIR – a region in space where fast and slow solar wind streams collide, creating a compressed area with enhanced plasma and magnetic fields. The Kp index was 7 or more for four three-hour periods. This pushed the maximum usable frequency over a 3,000km path below 14 MHz at times, which wasn't conducive to good DXing. On Thursday, the 5th of June, it looked like we were past the worst, and the Kp index was back to a more reasonable 2.33. Meanwhile, the solar flux index declined from a recent high of 164 on the 31st of May to a low of 134 on the 5th of June. HF propagation was being driven by the geomagnetic conditions, with a general lowering of the maximum usable frequency. Next week, NOAA predicts that the solar flux index will start the week at around 155 and remain around 150. More worryingly, geomagnetic conditions are again predicted to be unsettled after this weekend, with a maximum Kp index of 6 on the 13th of June. So, unsettled geomagnetic conditions, plus the HF summer doldrums, mean HF DX via F2-layer propagation may be hard to find. So, make the most of the 10m Sporadic-E short-skip openings instead! And now the VHF and up propagation news from G3YLA and G4BAO Last week offered an example of what a good Sporadic-E season should look like. On Tuesday, the 3rd of June in particular, the 6m band sounded like the 20m band and, at its peak, activity extended all the way up to the 2m band. This coming week has an unsettled flavour with several areas of low pressure and weather fronts involved, together with heavy showers in between. This means rain scatter will be a supported mode on the GHz bands. There is a slight hint of a slow improvement during the week, but not really any high pressure showing up until right at the end of the coming week. So, there is a chance of Tropo propagation for the 2nd 144MHz Backpackers Contest on Sunday, the 15th. Meteor scatter is always interesting in June, with four showers to play with during the month. The early ones are the Arietids, which peaked on Saturday, the 7th of June – good news for the 50MHz UK Activity Contest on Thursday the 12th. The Zeta Perseids peak tomorrow, the 9th of June, and there will be a couple of other showers later in the month. This is probably also why the Sporadic-E prospects improve about now. Aurora has also been much in evidence recently. Despite the light summer evenings and short nights, the chances of radio aurora continue to be important, so monitor for high Kp values above about 5. The advice for some who have not yet worked Sporadic-E is to check the 6m band around teatime. There are, of course, usually two primary periods when Sporadic-E is more likely: one in the morning, and the second in late afternoon and evening. A morning opening may repeat in the afternoon in similar locations, although usually the weather trigger may have moved a little in the meantime. Check the jet stream charts at propquest.co.uk  by following the Sporadic-E blog tab. The daily commentary will highlight the important directions each day. You can hopefully test out the system on Thursday, the 12th of June, in the 50MHz UK Activity Contest. EME path losses were at their maximum with apogee, when the Moon is at its furthest from the Earth, on Saturday, the 7th of June. Declination reaches a minimum on Wednesday, the 11th, so Moon windows are short and peak elevation is low. 144MHz sky noise peaks around the 11th and 12th of June. EME conditions were classed as poor this weekend and are classed as poor-to-moderate on the 14th and 15th of June. And that's all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 29th of May 2025 Last week's high-speed solar wind, from a massive coronal hole on the Sun, took its toll on the HF bands. However, this week has been little better. Another coronal hole running diagonally across the Sun has been emitting particles that have pushed the Kp index up to a maximum of 6.67 w,hich puts us into visible aurora territory. Nevertheless, some DX has been worked, including CP4BT in Bolivia, ZP5KP in Paraguay and V44KAI in St Kitts and Nevis. These were reported by Karl, G0SKW on the CDXC Slack alerting system. BA100IARU, a special event station celebrating the 100th anniversary of the International Amateur Radio Union, has been active from Beijing, China and has been worked on 20m CW. The station's QRZ.com page provides real-time updates on which band the operators are working on. Most of the DX has been worked on 21, 18 and 14 MHz, with the 10m band mostly closed due to the summer doldrums. There have not been too many Sporadic-E openings on the 10m band. Instead, most of the Sporadic-E reports have been on the 6m band. The solar flux index has increased, standing at 144 on Thursday, the 29th of May, which is always a good sign. The solar disk is looking quite healthy at the moment with spots in both hemispheres. As of last Thursday, the 29th of May, there had been 43 C-class flares over the previous five days, as well as six more potent M-class events and one X-class flare. So, the Sun is still very active. Next week, NOAA predicts that the solar flux index will reduce again, perhaps going as low as 110 by Wednesday, the 4th of June. It does look like we are in for a rough ride with unsettled geomagnetic conditions forecast for the coming week. Looking further ahead, the 13th and 14th of June seem to be the worst days, when a Kp index of five is forecast. As usual, a high Kp index can result in lowered maximum usable frequencies and aurora-like conditions, with a slow recovery. And now the VHF and up propagation news from G3YLA and G4BAO The weather continues to be unsettled into the coming week, especially for northern areas, but with some drier and warmer spells in the south. There do not appear to be strong signs for any Tropo success, but there should be a chance of occasional rain scatter on the GHz bands. Some models suggest we are on the edge of high pressure over the North Sea. Others drive a deep low right across the country. This will resolve itself next week, but for now, it's not at all clear which forecast will win through. The prospects for meteor scatter are mostly random meteors, but towards the end of this wee,k the daytime Arietids will peak to enhance chances further. The solar auroral alerts keep coming, so it's reasonable to expect the chance of some radio response, such as watery-sounding signals on HF, even if we don't go to the full effects on VHF. It's certainly worth watching for those increasing Kp values. The Sporadic-E prospects often burst into life about now. So, after a few reasonable 6m band openings, like the one into southeast Europe on Wednesday the 28th, make sure you are ready for the first week in June – one of the prime weeks for Sporadic-E opportunities. This is partly due to meteor input and the fact that the tidal winds in the E region are taking on their summer pattern. The long polar days mean that the low-pressure weather patterns are also beginning to affect the northern polar routes to China and Japan across northern Russia, with their possible weather triggers, like jet streams. EME path losses are increasing again. Moon windows shorten, and peak elevation is falling as the Moon's declination goes negative again on Wednesday, the 4th of June. 144MHz sky noise is low and remains low as the week progresses. And that's all from the propagation team this week.

GB2RS News Sunday, the 25th of May 2025 The news headlines: Apply to become the RSGB's new CW Champion The Tonight@8 series continues in June with Morse code Could you be the RSGB's new STEM Champion? As part of the RSGB's ongoing strategy to take amateur radio to new and diverse audiences, it is seeking to appoint a volunteer CW Champion. Whilst the need for a CW test has been removed from the licensing requirements, there is still a strong interest in the mode. Recent communications and activity involving Morse have received high levels of interest, and the Society would like to do all it can to encourage and promote CW within the hobby. This new role will take the lead with activities including managing RSGB web content relating to Morse code and contributing to the GB2CW broadcasts. The volunteer will also be tasked with building a team of enthusiastic individuals who can support CW-related activities undertaken by the Society. This role is intended to help take Morse to new audiences with an emphasis on learning and development to further the skills of RSGB members. Read the full role description, as well as details of how to apply, by going to rsgb.org/volunteers The next webinar in the Tonight@8 series is on Monday, the 2nd of June. The RSGB's Morse Test Coordinator, Eric Arkinstall, M0KZB, will lead the webinar and will be joined by a panel of Morse experts, including RSGB Morse Assessor and GB2CW broadcaster Michael Topple, GM5AUG. The presentation will include an introduction to Morse, how to start learning the code, the different types of Morse keys and the Achilles heels that can occur when learning Morse. There will also be a panel discussion on how they each became interested in the mode and how they overcame any problems they have encountered along the way. Find out more about this and future webinars on the RSGB website at rsgb.org/webinars Would you like to become the RSGB STEM Champion? This new volunteer role is part of the Society's strategic plans to encourage more young people into STEM careers and to demonstrate the contribution that amateur radio can make to those careers. The focus of the role will also be to develop and strengthen the Society's relationship with the STEM Learning organisation. The Champion will need to work closely with licensed STEM Ambassadors, attend STEM events to promote amateur radio, and support radio amateurs who would like to become STEM Ambassadors. The STEM Champion will work closely with the Board Liaison, Ben Lloyd, GW4BML and members of the RSGB Outreach team. To make the most of the role, you will need to have the right skills and experience. This includes being a STEM Ambassador with involvement in the STEM sector, and also being proactive, enthusiastic, organised and willing to find new ways to achieve the role's objectives. For full details of this challenging but rewarding role and how to apply, see the RSGB website at rsgb.org/volunteers Staff and volunteers from the RSGB had a successful time at the Dayton Hamvention last weekend. The event was a brilliant opportunity to engage with radio amateurs from around the world and resulted in 134 people joining the RSGB or renewing their membership. These included ARRL First Vice President, Kristen McIntyre, K6WX and ARRL CEO, David Minster, NA2AA, as well as Phil Karn, KA9Q and many more who took advantage of the new RSGB Digital Membership. Members of the RSGB team are always delighted to hear how much the Society's publications, videos and other content are appreciated by radio amateurs in other countries.

Using CW on the 80m band, the exchange is signal report and serial number.    Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 22nd of May 2025 A high-speed solar wind, originating from a massive coronal hole, took its toll on HF this past week. During the weekend of the 17th and 18th, the Kp index was above four for nine of the three-hourly recording periods. Unfortunately, the feed from the Dourbes Digisonde failed over this period, so we can't comment on what effect this had on maximum usable frequencies, or MUFs for short. Later in the week, geomagnetic conditions improved, despite the coronal hole still being Earth-centric, and the Kp index fell to more reasonable levels, sometimes in the ones and twos. An M3.2 solar flare was observed at 08:21 UTC on the 19th of May. The source was located off the northeast limb, so perhaps we can expect more as it turns to become more Earth-facing. Unfortunately, the solar flux index also fell to lower levels, reaching 119 by Thursday, the 22nd. In fact, on that day, it had been below 120 for more than seven days. But all is not lost, as a solar flux of more than 100 is usually enough to keep the HF bands open. MUFs over a 3,000km path have generally reached 21 MHz and have often peaked at 24 MHz at times. It is quite normal for the F2-layer MUF not to reach 28MHz due to a change in the ionospheric chemical make-up in the summer – the so-called summer doldrums. However, Sporadic-E may keep 10m alive, so don't write the band off. Propagation, at the moment, favours paths into the southern hemisphere, although each band can have different characteristics at different times. A quick play with the propagation tool at tinyurl.com/propcharts  will show you what we mean. Next week, NOAA predicts that the solar flux index will remain around 120 until the 27th of May, after which it could rise to 140 by the end of the month. Unsettled geomagnetic conditions are forecast for the period from the 28th of May to the 2nd of June. This could see the Kp index peak at five or six with corresponding drops in the MUF and DX. As we are now on the downward portion of this solar cycle, we may expect more geomagnetic disturbances from coronal holes and coronal mass ejections. And now the VHF and up propagation news from G3YLA and G4BAO The long run of fine settled weather seems to have drawn to a close. We have a period of changeable and, at times, wet and windy weather to deal with over the coming week. I doubt we will see much, if any, Tropo except perhaps towards the end of the week as some models show a new high building as we move into June.  Before then, the various fronts and showers will bring several spells of rain and a much greater chance of rain scatter on the GHz bands than recently. The solar conditions have again provided weak auroral events, with fluttery signals on the HF bands being a good indicator, since the bright evenings and early dawns leave little chance of any visual clues. As usual, the measure to follow is the Kp index. So, look out for values of Kp going above five to generate interest. Meteor scatter is declining as the last of the Eta Aquariids play out, following a long tail from the peak on the 6th of May. Meteors also make up the content of Sporadic-E because, as they burn up, they produce long-lived metallic ions that can be focused into thin layers of Sporadic-E. There are some less well-known meteor showers in June. So, next week there may be more to say. In the meantime, random meteors and declining Aquariids will have to suffice. Now, on to Sporadic-E. This is beginning to be the primary mode in these summer weeks. It is sensible to check during main operating windows in the morning, late afternoon and early evening. Ideally, we require meteor input, a low Kp index, plus some weather triggers to set up atmospheric gravity waves which produce the right wind shear in the E region. Jet streams are usually the best clues for where Sporadic-E might form.  Use the daily Sporadic-E blog on the Propquest website to get an insight of the current day's weather patterns – see propquest.co.uk   If you have very limited time and have still not worked Sporadic-E, just checking 50MHz in the late afternoon will ensure that you make a start this year. EME path losses are still falling as the Moon reaches perigee, its closest point to Earth, on the 26th of May. Moon windows and peak elevation are again rising, reaching a maximum on the 29th of May. 144MHz sky noise is low and remains low as the week progresses. And that's all from the propagation team this week.

Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 15th of May 2025 This week, you could be forgiven for thinking that the Solar Cycle 25 maximum is now over. With a reduced solar flux index and an almost blank Sun, there was little to get excited about. By Thursday, the 15th of May, the SFI was 122, but previously, on the 12th, it had been down to 116, which is the lowest it has been for some time. There is still a lot of solar activity going on, but most of it is not conducive to good HF propagation. Over the past week, we have had two X-class solar flares and five M-class events. The X-class events were associated with coronal mass ejections, but these appear to have been directed away from Earth. A fast solar wind has resulted in the Kp index standing at four for a lot of the time, namely on the 9th and 10th of May and again on the 14th and 15th. Unfortunately, this is not uncommon at this point in the solar cycle and adds some evidence that we are now in the declining phase of Cycle 25. Next week, NOAA predicts that things may improve with the SFI set to rise from the 19th of May. It forecasts the SFI will start the week around 115, but then will climb steadily, reaching 145 by the 1st of June. After a brief rise on the 19th with a Kp of four, things then become more settled with a Kp of two between the 22nd and the 28th of May. A large elongated coronal hole became Earth-facing on 16th May, which could cause raised K indices and lower MUFs from today, the 18th of May, onwards. It looks like the best HF F2-layer conditions may occur between the 22nd and 28th of May. And don't forget, despite the HF doldrums, we are now well into Sporadic-E season with short-skip occurring, predominantly on 10m. But more of that shortly. And now the VHF and up propagation news from G3YLA and G4BAO The prolonged spell of high pressure is likely to remain until near the end of this week, so there is plenty of time to get some more Tropo in the log. Cloudier and cooler air over eastern Britain at the end of last week may enhance the Tropo by adding moisture under the inversion. For most places, the strongest Tropo conditions will be overnight and early morning, then they will degrade as the daytime heating destroys the surface temperature inversion. Meteor scatter is declining a little, apart from a few stragglers from early May showers, so it's probably better to keep to the early morning period as your go-to time for meteor scatter to focus on any random input. Rain scatter is unlikely until next weekend, but it might be worth thinking about the GHz bands from this Friday, the 23rd of May, onwards. Aurora is a different matter, and the solar activity is likely to keep things interesting as a large sunspot group rotates into an Earth-facing position. Strong Es opened on Wednesday, the 14th of May, so it's definitely the season to be checking the upper HF and lower VHF bands for Sporadic-E. In this recent opening, the Dourbes ionosonde peaked at an Es critical frequency of 14 MHz, which is a very high value, even for mid-season. There were strong signals from the central Mediterranean on 6m CW, and some may have even got some 2m digital mode action from the brief opening. Check the Propquest NVIS tab for the day to see the details of this event. Although weak jet streams were present, the opening may well have been helped by some very intense, slow-moving thunderstorms over France. Remember to start checking on 10m and, if it's open, look to the higher bands of 6m, 4m, up to 2m. EME path losses are still falling. Moon declination ended last week at minimum but goes positive again this Thursday, the 22nd of May. Moon windows and peak elevation are again rising. 144MHz sky noise is high this weekend, falling back to low as the week progresses. And that's all from the propagation team this week.

Using all modes on the 4m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 8th of May 2025 Active region 4079 turned out to be not quite so bad as we had predicted. The sunspot was large, about ten times the width of our Earth, so we expected it to be more active. It was regions 4081 and 4082 that produced most of the flare activity last week. Two filament eruptions also occurred within two hours of each other. The first event began at 16:20 UTC on the 6th of May in the southern hemisphere and was responsible for a plasma wave across the surface of the Sun. The second filament eruption began in the northern hemisphere around 17:50 UTC to the northeast of AR 4079. A large amount of plasma was flung to the north. The filament eruptions on Tuesday, the 6th of May, did produce coronal mass ejections, but an Earth-directed component was not apparent. So we dodged a bullet! The solar wind speed remained high for most of last week which didn't help propagation. It did help to push the Kp index to five across the weekend of the 3rd and 4th of May. Things were more settled later in the week. On Thursday, the 8th of May, the solar wind speed was down to around 500 kilometres per second, the Kp index was three, but MUFs over a 3,000km path were still down at about 20 MHz. An Earth-facing coronal hole may add to the solar wind this weekend, the 10th and 11th of May. It looks like summer HF propagation is kicking in, with lower MUFs during the day but higher ones at night. Next week, NOAA predicts that the SFI will be in the range 155 to 165. Settled geomagnetic conditions are forecast for the beginning of this coming week, but unsettled geomagnetic conditions are expected for the 16th to the 19th of May. At that point, we could see the Kp index rise to five again, coupled with poorer propagation and reduced MUFs. And now the VHF and up propagation news from G3YLA and G4BAO Tropo has been a key propagation mode during the previous couple of weeks, but there have been variations in the location and timings of these conditions. Sometimes this will be due to increased moisture below the temperature inversion, so although the cloudier areas have been cool, they have probably done better for Tropo. This is due to the improved quality of the inversion, which performs better when there is a big moisture contrast across it, as you find with these layers of cloud.  Otherwise, we find that the better conditions are driven by night-time cooling, forming a low inversion near the ground which tends to disperse during the morning as the Sun warms it away. This should still be beneficial for the 70cm UK Activity Contest on Tuesday, the 13th of May, over eastern areas, but perhaps less so farther west. Good conditions will last into next week, but not everywhere. The main change will see an area of showery rain, possibly thundery, moving north into western Britain this weekend and perhaps some central areas early next week. This raises the prospect of some GHz band rain scatter in the west. The Eta Aquariids meteor shower peaked last week. In the decaying tail of activity, together with other lesser showers, this should keep an enhanced meteor input for the coming week. The Sporadic-E season typically runs from May to mid-September and the daily jet stream blogs have started on www.propquest.co.uk.  As usual, the main season offers two periods of activity, one in the morning and the second from late afternoon to the evening. Remember, Es is not guaranteed since it depends upon many factors, but jet streams help, and these are shown on the website maps. Use the map clusters to find out where any activity is starting on 10m and then follow it up in frequency through the lower VHF bands. EME path losses are at their maximum but falling after apogee on Friday, the 9th of May. Moon declination is negative, reaching a minimum this coming Thursday, so we'll have very short Moon windows and low peak elevation. 144MHz sky noise is moderate, increasing to high by next Friday. And that's all from the propagation team this week.  

Cómo sigue el despliegue de #5G en #ESP? Tenemos datos nuevos de CNMC que nos dan pistas muy importantes. El número de estaciones base sigue creciendo de manera casi lineal pero lo hace con marcadas diferencias. Mientras que en N28 (700 MHz) hay dos operadores líderes (aunque según los dato CNMC el líder es MasOrange) y un tercero a distancia para la banda N78 (3,5 GHz) hay un líder destacado (Telefónica). Sin embargo, el porcentaje de clientes que utilizan estas redes #5G es en Vodafone España el mayor (57%), aunque en números absolutos, teniendo en cuenta su tamaño, es MasOrange con 8,4M la que ocupa la primera posición). Y los patrones de tráfico por cliente, mes y G son marcadamente diferentes según los operadores. La noticia de este trimestre es que MasOrange y Vodafone España han vuelto al crecimiento (más del 6% YoY). Veremos a dónde conduce. Esta diferencia de patrones de uso hace que aprox el 43% del tráfico móvil de la red de Telefónica sea originado por clientes de Digi Spain Telecom. Una cifra que no hay que olvidar!

This year's Youngsters on the Air Summer Camp will take place between the 18th and 25th of August at the historical Château [SHA-TOW] de Jambville [ZHOM-VIL] near Paris in France. The event is being organised by the French national amateur radio society, REF, and the IARU. It is a chance of a lifetime for young RSGB members to represent their country and their national society. If you are ready for exciting experiences, would like to make new friends and want to help shape the future of amateur radio, then the RSGB would love to hear from you. If you'd like to find out more about what's involved and to submit an application, go to rsgb.org/yota-camp The closing date for applications is the 2nd of May for Team Leader and the 16th of May for Team Members. Apply today and don't miss out on this fantastic opportunity. The RSGB is looking to recruit volunteers from the exam tutor community to help pre-screen documentation prior to public release as part of the process of improving the quality of documents issued by the Exam and Syllabus Review Group (ESRG). The Exam Tutors Review Panel is intended to be an informal group of approximately six tutors who are currently involved in providing training for amateur radio licence exams at any of the three current levels. Panel members will be asked to use their skills to help improve the quality of the syllabus, the questions in the published question bank and other published documentation. They will receive advance copies of documents that are due to be published, and they will be expected to return any comments within an agreed timescale, which typically will be two weeks. The ESRG is not obliged to accept the recommendations from panel members, but if they do not accept a recommended change, they will explain why. All documents and additional correspondence sent to panel members will be under an embargo until the final versions are released to the public. The Exam Tutors Review Panel is intended to run for an initial six months and will then be reviewed. If you are interested in becoming a member of this panel, please email Board Director Len Paget, GM0ONX via GM0ONX@rsgb.org.uk The RSGB would like to thank everyone who joined the RSGB 2025 AGM which was held yesterday, the 12th of April. If you missed the live event, you'll still be able to watch the full livestream on the Society's YouTube channel. As well as the formal AGM business, the Board answered questions from RSGB members on a wide range of topics. You'll also be able to watch the President's review of 2024, delivered by John McCullagh MBE, GI4BWM, who was the RSGB President at the time.

Using SSB on the 80m band, the exchange is signal report and serial number. On Thursday the 17th of April, the 70MHz UK Activity Contest runs from 1900 to 2130UTC. Using All modes on the 4m band, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 10th of April 2025 A fast solar wind caused some disruption last week, often sending the Kp index up to five, with many three-hour periods in excess of four. The solar wind speed was in the 600-700 kilometres per second range, which caused a moderate, G2, geomagnetic storm and visible aurora at higher latitudes mid-week. Glancing CMEs that left the Sun on the 9th of April brought a small chance of enhanced geomagnetic activity at the end of the week. Meanwhile, the solar flux index declined slightly from a high of 184 on the 5th of April to 167 on Thursday the 10th. There have been quite a few C-class solar flares, but only two M-class flares and no X-class events over the past seven days. This geomagnetic activity has taken its toll on HF propagation, with lower critical frequencies at times and lower MUFs. This, coupled with the start of a change to summer ionospheric conditions, has meant that MUFs over a 3,000km path have often struggled to get past 19.7MHz at times. We have probably seen the best of the long-range 10m propagation until the autumn. But we will have Sporadic-E and its associated short skip from next month to make up for it. Next week NOAA predicts that the solar flux index will fall further, perhaps to between 135 and 140 by the 15th of April. Geomagnetic conditions are also likely to improve with a Kp index of two to three, forecast for the period after tomorrow, the 14th of April. We may expect more problematic geomagnetic conditions, with a predicted Kp index of four, from the 21st to the 24th of April.   And now the VHF and up propagation news from G3YLA and G4BAO The long spell of fine settled weather and strong Tropo is leaving us for a while, starting this weekend, and the high pressure is giving way to slow-moving areas of low pressure with cloud and rain for the coming week. Although it won't rain all the time it will be considerably wetter than recent weeks, with some heavy spells of rain at times and good prospects for rain scatter on the GHz bands. It is possible that there could be some thunder in the heavier rain, so it's now the season to be aware of lightning risk. The meteor scatter prospects are staggering towards the 22nd of April Lyrids, which peak on Tuesday of the following week, so we're still probably relying on random activity for most of this coming week, but with improving chances. The solar conditions have been feeding low-level auroral activity and it remains a good time of the year when some effective auroral conditions can appear - so stay alert to the state of the Kp index, just in case. The good news at this time of the year is that Sporadic-E will eventually make an appearance, usually on 10m or 6m, and is quite often first picked out on the digital modes. It will be into late April before we need to get too excited about this, but there is no harm in getting a set of beacons in mind for tracking an opening. Remember the main characteristic of Es is that it starts on the lower frequencies like 10m, and works up through 6m to 4m and then finally 2m in a high-summer opening. EME path losses are at their maximum at apogee this evening, the 13th, and Moon declination is negative and falling further. Moon windows will continue to shorten with peak elevation reaching only eight degrees at the end of next week. 144MHz sky noise starts the week low but will increase during the week to more than 2300 Kelvin on Friday. And that's all from the propagation team this week.

GB2RS News Sunday, the 30th of March 2025   The news headlines: RSGB AGM – your chance to ask the Board a question The RSGB has published new forms for exam question queries The April Tonight@8 webinar – using a glue stick in a homemade 40m receiver Do you have a question about the RSGB's strategy? Perhaps you have a query about recent licence changes? Or maybe you'd like to understand more about membership growth? Whatever the topic, the Society is asking you to get in touch. RSGB Board members will be answering your questions during the RSGB 2025 AGM on Saturday, the 12th of April. You can submit your question in three ways; live via Zoom, send a written question in advance, or during the live chat on the day. If you'd like to ask a question about the formal part of the AGM, you'll need to do this via Zoom or by submitting a written question in advance. Don't miss out on this opportunity to discuss what matters to you. Your participation in the AGM is important, and the Society looks forward to hearing from you. Find out more about how to be involved and the deadlines for submitting questions by going to rsgb.org/agm As part of its modernisation of the exam systems, the RSGB has introduced online forms for reporting possible errors found in exam questions. These forms replace the current procedure of writing to the Exam Department. RSGB Examinations Standards Chair Tony Kent, G8PBH, explained that there are two forms. The first can only be submitted by exam candidates and is to formally challenge questions in actual exams, where the outcome of a challenge may affect a candidate's result. The second form can be submitted by anyone and is for informal queries of published exam questions, for example, in mock exams. A separate form is needed for each question that you challenge. Please check carefully that you are using the correct form, otherwise, it may delay the process. Your query will be considered by the RSGB Examinations and Syllabus Review Group, who will let you know the outcome. For more information and to find the forms, go to rsgb.org/exam-challenges The next webinar in the RSGB's Tonight@8 series will be with Nick Wood, M0NTV, on Monday, the 7th of April. Nick will show you how to use a regular glue stick housing in a rather novel way to form the basis of a variable tuning inductor in a homemade 40m receiver. After a brief description of a Direct Conversion Receiver and a short technical explanation of how it works, Nick will dive into four separate modules. At the end of the webinar, he will string it all together, and you'll be able to see some video footage of how it sounds and what it can do. Visit rsgb.org/webinars  to find out more. Join the presentation live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat.

Using CW and SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and serial number. SP stations also send their province code.  Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 27th of March 2025 Last week's space weather was dominated by a large coronal hole on the Sun. This was probably one of the largest we have seen for many years. Moderate, G2, geomagnetic storming was observed following the arrival of a solar wind stream from the hole, with the wind speed exceeding 600 km/s on Wednesday, the 26th. This pushed the Kp index to 6.33, depressing the MUF slightly. Luckily, the daytime MUF over a 3,000km path mostly stayed above 28 MHz, but it was slow to rise on Thursday, the 27th, when it took until 0900 UTC to reach 28 MHz. At the time of writing, the solar wind speed was more than 800km/s, so we can expect more disruption until at least Saturday, the 29th. Meanwhile, the solar flux index declined to 152 by Thursday, the 27th, with only four small sunspot regions visible. CDXC members have been discussing working New Zealand in the morning at the ZL sunset, often on low power. Listen and look for ZL4OL and ZL2CC, usually on FT8, but if conditions allow CW and SSB. 20m or 40m seems to be the favourite, and the VarAC data mode seems popular in ZL as well. Next week, NOAA predicts the solar flux index will climb again, perhaps to 180 by the 4th of April. However, unsettled geomagnetic conditions are forecast again, beginning on the 3rd. We may expect the Kp index to reach six, which could be the start of at least ten days of disruption. And now the VHF and up propagation news from G3YLA and G4BAO The overall picture for the weather patterns in the coming week is that of high pressure, which means that Tropo should be available as a good mode for VHF bands. There can be quite strong temperature inversions in the region of large well-developed areas of high pressure. The best performance will usually be around the edges of the high where the height of the inversion and ducting layer is typically between 0.5km and 2km above the ground, and can cover large distances for excellent DX prospects. Occasionally, a shallow ducting layer can form near the ground overnight but often disperses by mid-morning. If you are in a good inversion region, try SSB or CW on the VHF/UHF bands, as paths of up to 1,500km can often be achieved from a good ‘tropo lift'. The reverse side of the high-pressure systems is that we will have low pressure nearby, mainly to the north and west of the UK. Any potential for rain scatter will mainly be over northwestern Britain, although an active front that was moving south on Friday, the 28th of March, was a good candidate for chance rain scatter on the GHz bands. The prospects for meteor scatter are still largely dependent upon random meteors, which are usually best in the hours before dawn. Current solar activity will continue to trigger auroral alerts in the coming week. Now onto Sporadic-E, and last week we had a few out-of-season isolated foEs ‘blips' to between 5- 7 MHz, which was enough to produce propagation on 10m and 6m, albeit very fleetingly. There have already been some equinox-related 6m trans-equatorial propagation or TEP workable from the Southern part of the country, so keep an eye open late morning for Africa and late afternoon for South America.  EME path losses have continued to improve until perigee this morning, the 30th of March. Moon declination is still falling, and reached a minimum last Friday, the 28th. Moon windows will increase throughout the coming week. 144MHz sky noise is low, apart from Saturday the 29th when the Sun was close to the Moon in the sky, rising to moderate next Thursday before dropping back to low for the weekend. And that's all from the propagation team this week.

Avec l'arrivée de la 5G, les opérateurs télécoms vont absolument vouloir vous vendre une nouvelle manière de téléphoner. Il s'agit de la VoNR, ou Voice over New Radio. Cette nouvelle technologie permet de passer des appels vocaux directement sur le réseau 5G.Sur la 4G, cette technologie était nommée VoLTE pour Voice over LTE, LTE étant le terme anglais pour 4G.La VoNR promet une meilleure qualité audio et une connexion plus rapide. Mais bien sûr cela soulève aussi des défis techniques.D'abord, comment fonctionne la VoNR ?Actuellement, même en 5G, nos appels passent souvent par la 4G.Avec la VoNR, tout le trafic voix transite exclusivement via le réseau 5G, sans basculement vers des technologies plus anciennes.Cela signifie un temps d'établissement d'appel réduit et une meilleure qualité sonore, notamment avec des codecs plus performants.Quels sont les avantages et les défis de la VoNR ?La VoNR propose une architecture plus simple et plus efficace pour les opérateurs, et ce en évitant de maintenir des infrastructures mixtes 4G et 5G.Mais son déploiement reste pour l'heure limité. Car pour utiliser la VoNR, il faut une couverture 5G Standalone, c'est à dire la 5G Plus qui commence à peine à être déployée par les opérateurs télécom.De plus, tous les smartphones ne sont pas compatibles avec cette technologie. La plupart des smartphones haut de gamme sortis depuis 2021 intègrent toutefois le modem et le support logiciel pour cette 5G.Quand la VoNR sera-t-elle une réalité en France ?Actuellement, les opérateurs privilégient la 5G en mode Non-Standalone, sur la fréquence 700 Mhz. Il s'agit en réalité d'une 5G qui fonctionne sur l'infrastructure réseau de la 4G. Le 4G reste donc nécessaire pour passer des appel en passant par le protocole IP.Mais avec l'évolution récente de la vraie 5G, sur la fréquence 3,5 Ghz, et l'arrivée de nouveaux smartphones compatibles, la VoNR pourrait s'imposer progressivement.Et cela devrait d'abord bénéficier aux applications critiques nécessitant une latence ultra-faible et une qualité de service garantie.Le ZD Tech est sur toutes les plateformes de podcast !

C'est une nouvelle étape pour le réseau mobile en France : la 5G+, aussi appelée "vraie 5G", arrive progressivement chez Orange. Si Free avait été le premier à proposer cette évolution à ses abonnés, l'opérateur historique se positionne aujourd'hui avec une offre ambitieuse. Contrairement à la 5G actuelle, qui repose encore en partie sur l'infrastructure 4G, la 5G+ fonctionne en mode Standalone, totalement indépendante. Résultat : des débits améliorés, atteignant 1,5 Gbit/s en téléchargement et 200 Mbit/s en envoi, et une latence réduite de 3 millisecondes, un gain crucial pour le gaming ou le streaming haute définition. Seul bémol, la couverture en intérieur peut être légèrement moins efficace, en raison des caractéristiques des fréquences 3,5 GHz et 700 MHz utilisées.Pour accéder à la 5G+, trois conditions sont requises :-Se trouver dans une zone couverte.-Posséder un smartphone compatible.-Avoir un forfait adapté.Orange facilite cette transition en proposant une carte de couverture dédiée et en activant gratuitement l'option pour les abonnés 5G existants. Une autre possibilité est d'opter pour le forfait Série Spéciale 180 Go 5G+, facturé 41€/mois sans engagement (ou 36€/mois pour les clients Internet Orange). L'un des avantages de cette offre ? Une bande passante dédiée permettant de maintenir une connexion fluide, même dans les zones à forte affluence comme les festivals ou les sites touristiques.Grande nouveauté : la 5G+ intègre la technologie VoNR (Voice over New Radio), qui permet de passer des appels directement sur le réseau 5G. Contrairement à la 5G classique, qui bascule sur la 4G pour les communications vocales, cette technologie garantit une connexion continue et de meilleure qualité, sans interruption des usages internet en parallèle. Petite particularité : les utilisateurs ne verront pas de logo "5G+" sur leur smartphone. Cette indication n'a pas encore été implémentée par les fabricants, mais Orange assure que les abonnés remplissant les conditions en bénéficient automatiquement.Enfin, le forfait 180 Go 5G+ s'accompagne de deux offres attractives :-ChatGPT Plus offert pendant 12 mois (puis 23€/mois).-Netflix Standard avec publicité gratuit pendant 6 mois (puis 5,99€/mois).L'abonnement ChatGPT Plus est réservé aux nouveaux utilisateurs, tandis que la remise Netflix peut être appliquée à un compte existant, sous condition de ne pas avoir bénéficié d'une promotion au cours des 12 derniers mois. Avec ces avancées, Orange pousse un peu plus loin l'adoption de la 5G Standalone en France. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

À quelques jours du Mobile World Congress 2025 de Barcelone, Qualcomm frappe fort en dévoilant ses ambitions pour la 6G. John Smee, vice-président senior de l'ingénierie chez le géant américain des semi-conducteurs, qualifie 2025 d'année clé, marquant le début de la standardisation officielle de cette nouvelle génération de réseaux. Une annonce qui peut surprendre, alors que la 5G n'a pas encore atteint son plein potentiel.Qualcomm n'attend pas. Sa stratégie repose sur une intégration massive de l'intelligence artificielle (IA) dans les réseaux et les appareils. L'entreprise travaille déjà avec Nokia Bell Labs et Rhode & Schwarz pour démontrer les avantages des réseaux optimisés par l'IA. L'objectif ? Rendre les réseaux plus intelligents et plus adaptatifs, capables de réagir en temps réel à la charge du trafic, à l'interférence et à la mobilité des utilisateurs. Cette approche repose sur des protocoles natifs d'IA, qui permettront d'optimiser les performances réseau en fonction des applications et des besoins individuels. Une avancée qui profitera également à la 5G Advanced, lancée l'an dernier avec la version 3GPP Release 18, et qui constitue une étape intermédiaire avant l'arrivée de la 6G.Qualcomm mise aussi sur l'évolution des systèmes MIMO (Multiple Input Multiple Output) pour exploiter une nouvelle bande de fréquences, la FR3, située entre 7 et 15 GHz. Cette bande intermédiaire pourrait offrir jusqu'à 400 MHz de bande passante supplémentaire, avec des débits améliorés et une couverture comparable aux fréquences inférieures à 7 GHz. Les premiers tests du système Giga-MIMO FR3 sont prometteurs : ils montrent des gains significatifs en vitesse et en couverture. De son côté, Samsung et Arm, qui planchent aussi sur la 6G, estiment que cette nouvelle technologie pourrait atteindre des vitesses records de 1 térabit par seconde grâce au traitement parallèle de poche. Positionnée entre la bande FR1 (sub-6GHz) et la bande FR2 (au-dessus de 24 GHz), la FR3 se distingue par sa faible latence, son adaptabilité aux objets connectés (IoT) et sa capacité à transmettre des volumes massifs de données. Avec cette feuille de route, Qualcomm entend bien façonner l'avenir de la connectivité mobile et prendre une longueur d'avance dans la course à la 6G. Hébergé par Acast.

Et si l'accès à Internet ne connaissait plus de frontières ? La start-up française Constellation Technologies & Operations (CTO) pourrait bien ouvrir une nouvelle ère pour les télécommunications. Ce vendredi 28 février, l'entreprise a dévoilé une innovation qui pourrait transformer la connectivité spatiale : la première charge utile régénérative 5G millimétrique.Baptisée « Early Test », cette technologie utilise pour la première fois le spectre 5G mmWave depuis l'espace. Concrètement, elle permettrait d'offrir un accès à Internet ultra-rapide et à faible latence, même dans les régions les plus isolées, sans nécessiter d'infrastructures terrestres coûteuses. La 5G millimétrique (mmWave), qui exploite des fréquences élevées (24-100 GHz), est déjà reconnue pour ses débits exceptionnels et sa réactivité, idéale pour les usages intensifs en données. Jusqu'ici limitée aux zones denses à cause de sa faible portée et de sa sensibilité aux obstacles, cette technologie pourrait, grâce à CTO, s'affranchir des contraintes géographiques en passant par l'espace.Testée dans des conditions réelles, la charge utile de CTO a été intégrée avec succès à la plateforme ION de D-Orbit. Son lancement est prévu pour juin prochain, marquant une étape décisive dans la conquête de la connectivité universelle. L'ambition de CTO ne s'arrête pas là : devenir un acteur clé des services de connectivité spatiale et renforcer l'autonomie européenne dans ce secteur stratégique. Pour financer son développement, la start-up a levé plusieurs millions d'euros en moins de six mois et s'appuie sur une équipe de 30 experts issus du spatial et des télécoms.Contrairement aux constellations massives développées par certains acteurs, CTO mise sur un modèle collaboratif. Son infrastructure spatiale sera partagée avec les opérateurs télécoms, qui pourront ainsi étendre leur couverture sans lourds investissements. Une solution particulièrement adaptée aux zones rurales et isolées, où les réseaux terrestres restent difficiles à rentabiliser. Charles Delfieux, CEO de CTO, insiste sur l'importance de cette avancée : « C'est une brique fondamentale pour bâtir une infrastructure spatiale de télécommunications de nouvelle génération ». Avec cette innovation, la France pourrait bien s'imposer comme un pionnier d'un Internet sans frontières, accessible partout sur la planète. Hébergé par Acast.

Les horloges atomiques sont les instruments de mesure du temps les plus précis au monde. Elles permettent de définir la seconde avec une précision extrême et jouent un rôle clé dans des technologies comme le GPS et les communications. Mais comment fonctionnent-elles exactement ?La base du temps : les atomesContrairement aux horloges classiques qui utilisent des ressorts ou des pendules, les horloges atomiques mesurent le temps grâce aux propriétés des atomes. Plus précisément, elles exploitent la fréquence des oscillations des électrons lorsqu'ils changent d'énergie à l'intérieur d'un atome.L'atome le plus couramment utilisé est le césium-133. Lorsqu'il est soumis à des ondes électromagnétiques, ses électrons peuvent passer d'un état d'énergie à un autre en oscillant à une fréquence extrêmement stable : environ 9 192 631 770 oscillations par seconde. Cette fréquence est utilisée pour définir la seconde.Un processus précis de mesure1. Vapeur d'atomes de césiumOn commence par chauffer un échantillon de césium pour en extraire des atomes sous forme de vapeur.2. Sélection et excitationLes atomes passent ensuite dans un champ magnétique qui sélectionne uniquement ceux dans le bon état d'énergie. Ils sont ensuite exposés à des ondes micro-ondes à une fréquence proche de 9,19 GHz.3. Résonance parfaiteSi la fréquence des micro-ondes est parfaitement ajustée, un maximum d'atomes change d'état d'énergie.4. Détection et ajustementUn détecteur mesure combien d'atomes ont changé d'état. Si le nombre est maximal, cela signifie que la fréquence des micro-ondes est correcte. Sinon, elle est ajustée pour atteindre la valeur exacte.Une précision inégaléeGrâce à ce processus, les horloges atomiques modernes peuvent atteindre une précision telle qu'elles ne retarderaient que d'une seconde tous les 30 millions d'années ! Les modèles les plus avancés, utilisant des atomes de strontium ou d'ytterbium, sont encore plus précis.Applications des horloges atomiquesElles sont essentielles pour :- Le GPS : les satellites utilisent des horloges atomiques pour synchroniser les signaux et permettre une localisation ultra-précise.- Les télécommunications : elles garantissent la synchronisation des réseaux.- La physique : elles aident à tester des théories fondamentales comme la relativité d'Einstein.En résumé, une horloge atomique utilise les vibrations ultra-régulières des atomes pour mesurer le temps avec une précision inégalée, révolutionnant ainsi notre manière de compter les secondes !

New cellular network deployments are often associated with new frequency bands. 6G will likely use the upper mid-band from 7-24 GHz. It is called the “golden band” since it provides more spectrum than in current 5G networks and features decent propagation conditions. In this episode, Erik G. Larsson and Emil Björnson discuss the coexistence issues that must be overcome when operating in this band and how much spectrum we can expect to utilize. The future role of multi-antenna technology and its associated challenges are detailed, including the emerging “Gigantic MIMO” term. The prospects of exploiting near-field propagation effects in 6G and the road towards distributed cell-free MIMO are also covered. You can read Emil's paper about Gigantic MIMO here: https://arxiv.org/pdf/2407.05630 Nokia has a white paper about coverage evaluation: https://onestore.nokia.com/asset/213702 Music: On the Verge by Joseph McDade.

Foundations of Amateur Radio In the analogue world you throw up an antenna, turn on your radio, tune to a station and sound comes out. Aside from propagation restrictions, you don't particularly care when you do this. In contrast, if you fire up a WSPR or Weak Signal Propagation Reporter, each transmission lasts 110.6 seconds, every 120 seconds, starting on the even minute. An FT8 signal takes 12.6 seconds within a 15 second window. In other words, to use WSPR or FT8 you need to both transmit and receive at the right time for this to work. You don't need to go to modern modes to get the idea that time matters. Listening to any CW signal will give you an idea that time and timing is important. To give you a sense of what I mean, if you turn on your radio in the middle of a dah, in the middle of a letter, you're likely to hear the wrong symbol, perhaps decoding the partial dah as a dit and missing the first part, hearing a partial letter Q, dah dah dit dah as a dit dit dah, the letter U, and that is completely ignoring inter letter and inter word spacing. The point being that time matters for radio signals. So, if we're going to build a system that can handle radio signals inside a computer, we'll need to deal with time. Decoding is one thing, but what if you want to compare two radio signals from two different antennas? You can build a direction finding tool consisting of multiple antennas that can determine the direction of a signal by calculating the difference in time between when a signal arrived at one antenna and when it arrived at another. Of course, the distance between each antenna matters, so we'd need to deal with time in such a way that we can actually measure this. RF travels about 30 centimetres in a nanosecond. If that's not enough, what happens if you're digitising an analogue signal and sending it across the network to be processed? Not only do you need to track if information arrived at its destination or was lost in transit, if you're combining multiple signals, you'll also need to know when the information was captured. Which brings us to something entirely different and perhaps surprising. If I say "now", that moment is not the same for everybody on the planet. You might be listening to this on the train to work, your local repeater, on YouTube, or reading it on social media or in your email. Even me writing the word and reading it out loud are two different times. In other words, agreeing on time is not obvious. We could all look at the clock and share the information, but is that accurate enough? Do we tell each other how many seconds past midnight UTC, or do we need to know half or tenths of seconds? To use WSPR and FT8 it's generally enough to use the NTP or Network Time Protocol. It can be as accurate as 1 millisecond, but is that enough? To give you a sense of how precise we might need to be, a HF signal takes about 66 milliseconds to travel halfway around the globe. A mobile phone tower signal travels 6 kilometres in about 0.02 milliseconds, so NTP isn't really precise enough for what we might need. If you've played with a GPS, you might know that you can use it to determine when "now" is. It's theoretically capable of a 14 nanosecond accuracy, but by the time you actually use it, it's more like 100 nanoseconds. There's a million nanoseconds in a millisecond and a billion nanoseconds in a second. If you were to store nanoseconds as a 64-bit unsigned number, you could count between now and just over 584 years from now. Something else to consider. If you had two analogue to digital converters and you wanted to synchronise them, 1 nanosecond would allow you to get two 1 GHz signals to start at the same time, providing that you knew what time it was to that level of accuracy. If you're keen, look up maser. Before you point out that this means we'd be limited to anything below the 23cm band at 1.2 GHz, I'd like to mention that this is about representing all of it, 0 Hz to 1 GHz as one chunk of spectrum at the same time. In reality, you're much more likely to only want part of that, not to mention that we'd need to transport and process all that data as well. Which brings us to bandwidth considerations, but that's a conversation for another time. Credit to Nick VA3NNW, Kent AC1HJ, Dave VK6KV and Randall VK6WR for their thoughts and explanations.

Episode 26 - FirstNet and the 4.9 GHz Spectrum. This episode dives into the critical evolution of public safety communications, focusing on the recent FCC decision to establish a nationwide Band Manager framework for the 4.9 GHz spectrum, and discuss the evolution and deployment of the FirstNet System. Host Chris Tubbs interviews Chief Jeff Johnson, a leader in public safety technology and the development of FirstNet. Together, they explore the history, governance, and transformative potential of FirstNet and the 4.9 GHz spectrum in enhancing public safety operations with emerging technologies like AI, 5G, and augmented reality. The discussion emphasizes the importance of protecting and optimizing public safety spectrum, the lessons learned from past advocacy efforts, and a call to action for public safety leaders to remain engaged in ensuring the spectrum's effective use and governance.

As freezing temperatures approach, many of us are retreating indoors and relying on broadband to stay connected. While we all have an idea that bad weather can impact our broadband, some of the reasons as to how and why, aren't as well known. Broadband experts Virgin Media Ireland have shared the top three reasons your broadband connectivity isn't what it should be in stormy weather, some of the household appliances that may not be helping and how you can help improve it. Dispelling the Myths Bad weather or stormy conditions can cause sluggish broadband or even wipe it out altogether, but more often than not, a technical issue with your Wi-Fi signal isn't usually the reason why. One of the most common reasons why your Wi-Fi may be struggling to get up to speed in bad weather is actually down to human nature. Simply put, when the weather is bad, more people tend to stay indoors and use connected devices which can impact households across your area. When a greater volume of people increases their internet usage, the limited bandwidth available is quickly consumed, resulting in slow connectivity speeds. Bandwidth refers to the maximum amount of data that can be transmitted over an internet connection within a given period and it is shared by users within a particular area so, the more households that stay in and use connected devices, the slower your Wi-Fi is likely to be. While a storm can't interfere with your router's wireless signal, extreme weather can impact the Wi-Fi connection in other ways. Heavy rain, snow or wind can damage overhead cables supplying your broadband, causing significant outages or sluggish speeds. Severe weather, such as thunderstorms, can cause power outages that disrupt the infrastructure of cable internet providers, leading to service interruptions. Top 5 Household Items Slowing Down Your Wi-Fi 1. Microwaves Interference: Microwaves operate at a frequency of around 2.4 GHz, which is the same frequency used by many Wi-Fi routers. When a microwave is in use, it can cause significant interference with Wi-Fi signals, leading to slower speeds or temporary disconnections. 2. Cordless Phones Interference: Older cordless phones, especially those operating at 2.4 GHz, can interfere with Wi-Fi signals on the same frequency, causing disruptions and slower internet speeds. 3. Baby Monitors Interference: Many baby monitors also operate on the 2.4 GHz frequency, potentially causing interference with Wi-Fi signals and leading to reduced network performance. 4. Bluetooth Devices Shared Frequency: Bluetooth devices operate on the 2.4 GHz frequency as well. Although modern Bluetooth technology uses adaptive frequency hopping to reduce interference, having many Bluetooth devices active simultaneously can still impact Wi-Fi performance. 5. Smart Home Devices Network Congestion: Devices such as smart lights, thermostats, cameras, and other IoT (Internet of Things) devices can congest your network if you have many of them connected, especially if they are constantly transmitting data. Top 3 tips to improve your speeds 1. Avoid placing your router in areas with thick walls, near large metal objects, or close to electronic devices 2. Place your router in an elevated position and in an open space free of physical obstructions which could block the Wi-Fi signal. 3. Disconnect devices you aren't using and close unnecessary background programs on devices that you are - these could be hogging your bandwidth.

Foundations of Amateur Radio Have you ever attempted to download an email attachment, or watch a streaming service whilst your microwave was cooking lunch or dinner and noticed that something odd was happening, or is my asking that question the first time that you joined the dots? This phenomenon is not by accident, though it isn't on purpose. In 1947 the International Telecommunications Union, the ITU, was meeting in Atlantic City where the "delegate of the United States, referring to his request that the frequency 2450 Mc/s be allocated for I.S.M., indicated that there was in existence in the United States, and working on this frequency a diathermy machine and an electronic cooker, and that the latter might eventually be installed in transatlantic ships and airplanes. There was therefore some point in attempting to reach world agreement on this subject." Several things to unpack there. It's 1947 and experimentation is happening at 2,450 Mega-Cycles per second, what we call megahertz today; you might recognise the frequency as 2.45 GHz. At that time, experiments using radio frequencies for medical purposes has been in full swing for decades. Nikola Tesla wrote a paper on the subject that was presented in absentia to the American Electro Therapeutics Association in 1898. In 1947, a diathermy machine exists; today its used to aid with blood flow, muscle and joint pain as well as inflammatory and degenerative bone disease. There is a working electronic cooker, a microwave oven to you and I, and whilst the one you could buy in 1947, a Raytheon "Radarange", if you forked over $5,000, or $70,000 in today's money, had space for a 2 meter tall, 340 kilogram, 3 kilowatt behemoth, you have to admire the imagination that one day this would fit on an aeroplane to travel the world, let alone be available for $100 at your local supermarket. One other thing, I.S.M. or Industrial, Scientific and Medical is a concept we still use today. The idea being that there are uses for radio waves that are nothing to do with communication, like microwave ovens, steel smelting through induction heating, surgical uses like cauterising wounds, some cancer treatments and plenty more. One of the ideas behind ISM is that equipment operating in those frequencies must tolerate any interference generated by ISM applications. The other part of the ISM idea is that it's unlicensed, which is very attractive to people who experiment and why it became popular for other uses beyond heating your lunch. Consider that baby monitors, garage door openers, car security systems, video senders, cordless phones, wireless speakers and microphones, cordless keyboards and mice, radio controlled models, and smart power meters all share the same radio frequencies. Then there's Wi-Fi, Bluetooth, and Zigbee, also using the same 2.4 GHz ISM band. Yeah, even the two most popular network technologies on your phone and computer, Wi-Fi and Bluetooth are competing with each other and the microwave oven in the kitchen. There are six global ISM bands and six additional ones with specific local requirements. Things like industrial microwave ovens, Near Field Communications or NFC and LoRaWan use frequencies like that. You'll also find satellite communications, radio location, CB radio, radio astronomers and radio amateurs on those bands. So, why are these technologies sharing the same frequencies? Essentially because they're unlicensed spectrum. Just so we're clear, this doesn't mean that it's unregulated spectrum. All it means is that unlike licensed spectrum, you don't need to buy access to the spectrum to use it, but you do need to have compliant equipment when you do. Compliance depends on local laws, location, band and power levels. So, next time you need to watch a movie whilst cooking lunch, eat an apple or go outside and get some daylight onto your skin instead. A quick word on power. Whilst all these uses share the same frequency band, their human impact varies considerably. A Wi-Fi network uses a tenth of a Watt. A diathermy machine uses 250 Watts and produces a "gentle heat" at the surface of the skin, suitable for treatment. Contained inside a metal box, a microwave oven uses 1,000 Watts or more. Even that doesn't cook food from the inside out, instead it vibrates water molecules in the food, which heat up, which in turn cooks the food. It doesn't penetrate very far and doesn't work on frozen water, which is why you need to defrost your food before you can cook it. It's also why when you stand between your Wi-Fi router and the computer things slow down, or why your hand position on your phone or tablet can make a difference, since your body, made from 60% water, is blocking the signal. Finally, here's something to consider. A licensed radio amateur has access to some ISM bands, but does it require an amateur license to actually use any of those bands? In other words, if my amateur license doesn't permit my access to 2.4 or 5.8 GHz bands, can I legally use a transmitter in the unlicensed spectrum that is the ISM band on those frequencies? If you answered yes, and you're considering experimenting on the ISM bands, you'll find the Low Frequency Experimental Radio or LowFER, MedFER and HiFER community has already beaten you to it. Within the ISM regulations are provisions for all kinds of other experiments, generally using low power, sometimes a Watt, sometimes less, but you already know that my 10 mW beacon on the 10m band has been heard 13,945 km away, so there's plenty of opportunities to play.

On this episode of Full Spectrum, partner Chip Yorkgitis is going to give an overview of two items adopted by the FCC in late September. The first is a Report and Order that the Commission adopted at its open meeting on September 26 to allow non-geostationary satellite orbit space stations to conduct fixed satellite service downlink operations on a co-primary basis with existing users in the 17.3-17.8 GHz band. The second item he'll discuss is a First Report and Order that the Commission adopted two days prior to the meeting to modify the rules for FM terrestrial digital audio broadcasting systems.

Foundations of Amateur Radio Over the past few months I've been investigating the history of the IARU, the International Amateur Radio Union, to help it celebrate a century of amateur radio achievements. If you're a radio amateur and you pay anyone a membership fee, I have questions for you. Let me set the stage with a quote from the IARU: "All licensed radio amateurs benefit from the work of the IARU, whether or not they are members of their national IARU member-society. But every licensed radio amateur should be a member. Only by combining our efforts in this way can we ensure the future health of amateur radio, for ourselves and for future generations." That's straight from the IARU website. It seems like a lofty and worthy aspiration. Before I proceed, let me assure you that I'm absolutely committed to improving this hobby and this community, committed to strengthening its representation, its reach and increasing its activity levels. The IARU has existed for nearly a century. It consists of a global organisation and three regional ones, each working towards improving on, and advocating for, the amateur community. Governed by different constitutions each organisation pursues similar but not identical roles within its sphere of influence. Most, if not all IARU organisations are run by volunteers, people like you and I, who stick their hand up and help out, writing documents, attending meetings, updating websites, managing membership information and all the other things that the IARU apparently does. I say apparently because getting anything other than motherhood statements from any of the IARU organisations is like pulling teeth. To construct a historic list of elected office bearers, President, Vice-President, Secretary, Treasurer and various regional Directors is an exercise in archaeology and much of the information doesn't appear to exist. That also seems to be true for what the IARU is spending its money on, your money. The IARU is funded by the fees that we pay to the representative body in our country, either directly, or as a member of a club who contributes. In my case, if I was paying a membership fee to the Wireless Institute of Australia, like I did for a decade, some of that would pass to IARU Region 3 and then from there, some would pass to the global IARU secretariat. Multiplied by every country and every paying member in that country across a century, there are significant, and to the best of my knowledge, unaccounted for sums of money involved. Then there is the list of things that the IARU has achieved. I don't doubt for a moment that people have been working very hard, giving it their all, helping, working late, doing things above and beyond to make outcomes appear, as-if by magic, without any of the blood sweat and tears associated with the process. I suppose it's like sausage, nobody wants to see how it's made, and I understand the sentiment. What of the outcomes, the published results? Should they be secret too? At the moment the IARU claims that it represents amateur radio on the global stage and on its website lists its achievements, namely: 21 MHz, Amateur Satellite, WARC bands, more Amateur Satellite bands, more 7 MHz frequencies, easing of restrictions in relation to disaster communications, 136 kHz, 472 kHz, 5 MHz, 50 MHz in Region 1, international roaming, and emergency communications. Impressive list right? There's twelve achievements listed in all, across 100 years, with meetings in cities all over the globe, with hundreds of people participating. Mind you, it appears that only recently has some level of coordination emerged between where meetings are held, by and large, each organisation meets every few years, staggered so there's always a meeting in a different country every year. Those frequent flyer miles must be adding up. If only there was another way to communicate across the globe. So, let's look at this in terms of effort and reward. Let's say that across the globe that at any one point in time there are 100 people part of the IARU infrastructure across the four organisations, or 25 in each. It's a modest representation. Let's say that they each volunteered 1 hour per week, so 52 hours a year, 5,200 hours across the entire IARU per year, or 520,000 hours across a century. This means that each achievement took more than 43,000 hours of volunteer effort. Unless of course there was more achieved that is undocumented. Mind you, 52 hours a year per volunteer is also probably light on, potentially by orders of magnitude. I note that for example there's no mention of things like quashing the 2m proposal by France where the local aviation authorities were looking to acquire some extra spectrum, or negotiations in relation to 1.2 GHz at the ITU World Radiocommunication Conference 2023 or WRC-23 in Dubai, United Arab Emirates, held between 20 November and 15 December 2023. My point is this: What is the IARU doing? Is it really effective, or is it burning volunteer hours like it's going out of fashion? What is it spending your money on? Where is the record of all this activity? What level of accountability is there? Is your peak body looking at the IARU books? Are they holding the IARU accountable, or are they part of the problem? There is plenty of evidence that there are other issues too. As I said, I attempted to write down who was elected president in what year in which IARU organisation. Aside from missing decades of information, there are amateurs in that line up who served as president for 26 years. Imagine that, a representative body that elects the same person for nine straight terms. I'm not naming them, the information I have is incomplete; right now I cannot tell you who was previously elected across IARU Region 3, or list anyone between Hiram Percy Maxim elected in 1925 as the first IARU president and 2009 when Tim Ellam, VE6SH and G4HUA, was elected president to the global body, but it's unclear if he was the only president between 2009 and 2024 when he was re-elected. So, what do we do about this? First of all, am I just tilting at windmills or is this an actual issue that needs fixing and if so, what might that look like? Engagement would be my first guess. Is your club sending money to your peak body? Has it asked what the funds are used for? If you're a member of your peak body, have you asked them where the money goes and how much of it goes to the IARU and what it's spent on? Contacting your peak body and asking questions might be the first place to start, but if your peak body is dysfunctional as plenty of them appear to be, perhaps it's time to contact the president of your own IARU region and ask them what gives, that is if you can find out who they are. As I said, I think that our hobby is important, I think it needs advocacy, I think that takes money and effort, but right now I have very limited evidence that what we're doing and how we're doing it is the most effective way to go about it. What will you do about this? I'm Onno VK6FLAB

We'd love to hear from you! Send us a text message.In this episode of "Discover Daily" by Perplexity, we explore a big advancement in black hole imaging and delve into the history of the world's oldest dated printed book. The Event Horizon Telescope collaboration has achieved a remarkable feat by introducing "color vision" to their observations of supermassive black holes. By incorporating a new radio frequency of 345 GHz alongside the existing 230 GHz, scientists can now produce sharper, more detailed images, offering unprecedented clarity in visualizing these cosmic giants. This dual-frequency approach is expected to increase image detail by an impressive 50%, allowing researchers to better differentiate between the effects of Einstein's gravity and other phenomena near black holes.We then journey back in time to explore the Diamond Sutra, a Buddhist text printed in 868 CE that holds the distinction of being the world's oldest known dated printed book. Discovered in 1900 in China's Mogao Caves, this 16-foot-long scroll predates the Gutenberg Bible by nearly six centuries. Created using woodblock printing, the Diamond Sutra represents a pivotal moment in the history of information dissemination, showcasing the advanced state of printing technology in 9th century China. Its colophon, which precisely dates its production, provides crucial evidence for understanding the timeline of printing technology development.From Perplexity's Discover Feed: https://www.perplexity.ai/page/telescope-shows-black-holes-in-Rw6Pn5JnQnOznJxuapBCLwhttps://www.perplexity.ai/page/the-world-s-oldest-printed-boo-rIR81on4RhKLPnFLoG1YTwPerplexity is the fastest and most powerful way to search the web.

Dr. Paul Heroux discusses the dangers of Electromagnetic Radiation (EMR) and cell phones with Robert F. Kennedy Jr in this episode. You do not want to miss this episode for the health of you and your family, especially the Q&A at the end. Cell phones emit radiation in the radiofrequency region of the electromagnetic spectrum. Second-, third-, and fourth-generation cell phones (2G, 3G, 4G) emit radiofrequency in the frequency range of 0.7–2.7 GHz. Fifth-generation (5G) cell phones are anticipated to use the frequency spectrum up to 80 GHz.  Dr. Paul Héroux is one of the world's leading experts on EMR. He is a scientist with experience in physics (BSc, MSc and PhD), engineering, and the health sciences. He started his research career at Institut de Recherche d'Hydro-Québec in Varennes, Québec, an internationally reputed electro-technical laboratory. After rounding out his formation with courses in Biology and Medicine, he became interested in public health, and was appointed Associate Professor at McGill University's Faculty of Medicine, where he is the current Occupational Health program Director, and also Medical Scientist in the Department of Surgery of the McGill University Health Center.
