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.

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 !

Using all modes on 2.3 to 10GHz frequencies, the exchange is signal report, serial number and locator. On Wednesday, the 26th of March, the UK and Ireland Contest Club Contest runs from 2000 to 2100UTC. Using CW on the 80m band, the exchange is your six-character locator. On Thursday, the 27th of March, the 80m Club Championship Contest runs from 2000 to 2130UTC. Using SSB on the 80m band, the exchange is signal report and serial number. The CQ World Wide WPX SSB Contest starts at 0000UTC on Saturday the 29th of March and ends at 2359UTC on Sunday the 30th of March. Using SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and serial number.  Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 20th of March 2025 Last week was pretty unremarkable from an HF perspective. After the disturbed geomagnetic conditions on the 12th to the 14th when the Kp index rose to five, conditions were a little more settled. The solar flux index hit 204 on the 17th of March but then declined back to the 180s. Having said that things were settled, the Kp index did exceed four for three periods on the 19th, peaking at 4.67. This had the effect of reducing the MUF over a 3,000km path to 21-24MHz. We also had two M-class solar flares on the 17th and the 19th, with the latter causing a coronal mass ejection that may give Earth a glancing blow around the 22nd of March. As spring progresses, we may find the F2-layer MUF dropping as we move to summer ionospheric conditions, perhaps to be replaced by enhanced sporadic-E conditions on 10 metres instead. Next week, NOAA predicts that the solar flux index may drop further, perhaps hitting 150 on the 28th. Unsettled geomagnetic conditions are forecast for the 25th to the 28th, with a maximum Kp index of five. As we said last week, this is now a peak period for auroral activity, given the angle that the Earth makes with the Sun. The 'Russell-McPherron' effect is down to the alignment of the Sun and Earth around the spring and autumn equinox and means that you are twice as likely to experience the aurora in spring and autumn than in winter and summer. And now the VHF and up propagation news from G3YLA and G4BAO The recent fine weather has provided some useful Tropo. This has been mainly towards the east and into the near continent, which seemed like nice timing for the 1.3GHz UK Activity Contest last Tuesday evening. Despite this, many participants reported conditions as poor. The high is now moving away and by the time you hear this, it will be a predominantly low-pressure weather sequence from now on. This means limited Tropo in the coming week, and rain scatter comes to the fore as a mode of choice if you have a GHz band set up. The solar conditions continue to provide a trickle charge of auroral alerts, but not enough for any significant operating advantage. As usual the message is to keep on top of things by monitoring the Kp index for values over 5. Meteor scatter remains largely in the gift of random meteors, so it's an early start to catch the pre-dawn peak of random meteors if you are so persuaded. Lastly, a mention of Sporadic-E which is still in its close season. We have a while to wait until later next month when we could expect the occasional stirrings on 10m. EME path losses continue to improve until the Moon's perigee (its closest point to Earth) on the morning of the 30th of March. Moon declination has been falling, reaching a minimum yesterday, the 22nd. So again, we have short Moon windows and reduced peak Moon elevation. 144MHz sky noise started high on Friday the 21st of March but will drop back to low by the middle of next week. And that's all from the propagation team this week.

GB2RS News Sunday the 16th of March 2025 The news headlines: Final chance to get involved in British Science Week and share your activities Advance notice of how to ask the Board questions at the RSGB AGM The RSGB has launched new National Radio Centre web pages Today, Sunday the 16th of March is the last day of British Science Week 2025. If you live in the Derbyshire or Leicestershire area, pop along to the open day being held by South Derbyshire and Ashby Woulds Amateur Radio Group.

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 13th of March 2025 We've had another week of disturbed geomagnetic conditions with the Kp index at four or five for long periods. On the evening of the 12th of March, Kp was five and, at the time of writing, has stayed there for a total of five three-hour periods. This has taken its toll on the ionosphere with MUFs over a 3,000km path down to less than 24.7MHz during daylight. Meanwhile, the solar flux index rose to 160 on Thursday the 13th after hitting a low of 147 on the 7th. The best HF propagation was last weekend, the 8th and 9th of March, just in time for the Commonwealth Contest. This saw stations around the world romping into the UK, including signals from Australia, New Zealand, the Falkland Islands, Barbados, and many others. As contacts were limited to Commonwealth countries, it meant the UK had little QRM to contend with and it was fairly easy to fill the log book on 40m to 10m. Australia was still coming in at 59 after dark, and even British Columbia on the west coast of Canada could be worked with simple wire antennas and low power. This may have been caused by a pre-auroral enhancement, as the Kp index rose late on the first day of the contest. Next week, NOAA predicts the solar flux index may rise to 195 by the 21st. It also suggests that we may be back into calmer geomagnetic conditions with a maximum Kp index of two. This will be a welcome change and, if it happens, will no doubt result in better HF conditions. And remember, March is a good month for north-south contacts, such as the UK to South Africa and the UK to South America. But with the equinox just around the corner, auroras are twice as common due to the Russell-McPherron effect. Just as when two bar magnets attract one another when they are oriented oppositely, so opposite Bz components attract. During the autumn and spring equinox, this orientation enables a 'connection' to the Sun, thereby allowing the solar wind to stream in. And now the VHF and up propagation news from G3YLA and G4BAO The recent change to colder weather brought showers and potential rain scatter to the second half of last week. But this weekend we have lost the showers and gained a large region of high pressure to bring a hint of Tropo. It's not perfect, since in cold air highs like this, conditions are usually less than ideal, so don't expect too much from this particular area of high pressure.  The high will last until midweek before it slips away into eastern Europe and, on its parting, may allow some moisture below the inversion and will improve the Tropo prospects briefly. The second half of the coming week will be dominated by low pressure and back to rain-scatter as an option on the GHz bands. The solar conditions have continued to provide a few weak auroral alerts and it's worth continuing a watching brief on the Kp index for hints of activity; anything greater than a Kp of five is worth our interest. Listen out for watery-sounding signals on the LF bands and then check out the 10m and 6m bands for auroral signals. The next important meteor shower is the April Lyrids, but there's always the chance of random meteor scatter activity, particularly in the pre-dawn hours. It's still a little early to mention Sporadic-E, but it's always worth looking at the lower frequencies first, which means 10m and 6m. Check the graphs on Propquest for signs of spikes in the foEs, which is the critical frequency of the Es-layer. EME path losses continue to rise until apogee on Monday evening. Moon declination is still falling, reaching a minimum on Saturday the 22nd. So again, we have short Moon windows and reduced peak Moon elevation. 144MHz sky noise is moderate and rising to high by Friday the 21st. And that's all from the propagation team this week.

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.

Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is signal report, serial number and time. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 6th of March 2025 We started last week with geomagnetic disturbances that saw the Kp index rise to a maximum of 5.67 on the 28th of February and then hover around the 4.5 mark for the next couple of days. As predicted, the rest of the week went quite well, with the Kp index in the range of one to four. The solar flux index fell from a maximum of 210 on the 23rd of February to a low of 140 on the 2nd of March. It then climbed back to 160 on the 4th. Over the past week, we have had no X-class and only one M-class solar flare which was on the 5th. As we head into next week, it looks like all the sunspots in the Sun's northern hemisphere have now departed. Nevertheless, the southern hemisphere is still supplying lots of spots so don't panic just yet! HF conditions have been quite good. VK6IF and VK6IA in Western Australia were booming in on 28MHz USB on the morning of Thursday the 6th, as was VK9CU on the Cocos-Keeling Islands. Nigel, VP8TXF and Ian, VP8CIW have been operating from the Falkland Islands ahead of this weekend's Commonwealth Contest and have been worked from the UK on 20m-10m. They are there until the 10th, so get in quick. Other DX to be worked this week includes VU4AX Andaman Islands, 6Y7EI Jamaica, PJ7AA Sint Maarten Island, 4S7KKG Sri Lanka, TY5C Benin, 6W7/ON4AVT Warang Senegal, RI1ANE Antarctica and H44MS Solomon Islands. Next week, NOAA predicts that the solar flux index will start off around 150 and may then climb to 185 by the 16th. A large coronal hole became Earth-facing on the 6th, which may result in unsettled geomagnetic conditions this weekend, the 8th and the 9th. It looks like we can expect unsettled geomagnetic conditions around the 10th to the 16th, with a maximum predicted Kp index of five. And now the VHF and up propagation news from G3YLA and G4BAO The weather divides into two segments; the first, from the middle of last week through to the middle of next week, is rather changeable with low pressure nearby bringing rain or showers and potential for rain scatter on the GHz bands. Eventually, the unsettled weather ends with a cold northerly on Tuesday the 11th and this leads to a new high building from Wednesday into the weekend of the 15th and 16th March.  This is good news for Tropo and could possibly be of benefit to those in the UK 70cm Activity Contest on Tuesday the 11th in the western UK, but more generally for the FT8 70cm Activity Contest on Wednesday and the 50MHz UK Activity Contest on Thursday evening. We are still between major meteor showers and therefore must rely upon random activity for now. The next shower of note is the Lyrids on the 21st and the 22nd of April, so we have a while to go yet. The solar activity has continued to produce a regular supply of auroral alerts and fluttery signals on the LF bands, but with a lot of clouds in northwestern areas and southern parts just marginally out of reach for any naked-eye auroras. A few digital camera pictures did surface on the web.  Keep an eye open just in case though. Remember Kp equalling five or greater is where we need to be. Lastly, the Sporadic-E prospects are still relatively low with only the odd minor blip up to around a Sporadic-E critical frequency of 5 to 7MHz, often around the middle of the day. This contrasts with the morning and evening windows in the main season. It is enough to promote interest in the 10 or 6m bands, but almost certainly a fleeting moment. EME path losses rise all this coming week and moon declination falls with associated shortening Moon windows and reducing peak Moon elevation. The best results will therefore be early in the week. 144MHz sky noise is moderate this weekend, falling to low in the week commencing the 10th. And that's all from the propagation team this week.

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.

The Commonwealth Contest is a treasure hunt with amateurs in distant locations looking to make a QSO with you, so if you are not a regular contest participant or you have a simple HF setup, you might use the Contest as an opportunity to make DX QSOs. UK amateurs are travelling to the Caribbean, the Falklands and New Zealand, so your scope for QSOs is expanded, and many VK, ZL, VU and VE amateurs will be joining in too. This year the Contest takes place on the 8th of March, and you can find out more on page 38 of the March issue of RadCom and on the RSGB website via tinyurl.com/commonwealth-contest On Saturday the 29th of March, the RSGB National Radio Centre Coordinator, Martyn Baker, G0GMB, together with Andy Webster, G7UHN from the Radio Communications Foundation, will be delivering a talk in the Fellowship Auditorium at Bletchley Park. It will introduce people to the radio spectrum and how to get to grips with the fundamentals of radio transmission. The RSGB is delighted that its members can benefit from a 10% discount, reducing the price to £14.40. To find out more, go to the ‘What's on' section on the Bletchley Park website via bletchleypark.org.uk  If you'd like to visit the wider Bletchley Park site after the talk, RSGB members can gain free entry by downloading a voucher from rsgb.org/bpvoucher Amateur Radio Clubs On The Air is getting ready for a second weekend of operating on the 22nd and 23rd of March.

The Kp index rose to a high of five with visible aurora over the UK at times. Two large coronal holes are now both facing Earth. A solar wind stream flowing from these zones is expected to flow past Earth, possibly on Friday the 28th of February or Saturday the 1st of March. Active geomagnetic conditions with a Kp index of four are currently forecast for this weekend. There has also been more solar flare activity over the past seven days with an X2-class flare on the 23rd and ten M-class flares. The X-class flare occurred at 19:27UTC so had little effect in Europe as the Sun had set. Luckily, an associated coronal mass ejection was not Earth-directed. Another fast-moving CME on the 24th was also not Earth-directed. As we enter March it looks as though the Sun is still very active. The solar flux index stood at 180 on Thursday the 27th, after hitting 210 on the 23rd. Maximum usable frequencies over 3,000km are still reaching 34-35MHz around midday, while night-time MUFs are generally around 10-11MHz, with occasional openings on 20 metres. This week Bob, VP8LP on the Falkland Islands has been active on 10 metres SSB and has been worked from the UK. As we enter March this is a good time for North-South paths on HF, such as UK to South Africa and UK to South America. The spring equinox is also a good time for auroral conditions. NOAA predicts the Sun will start next week with an SFI of 190, perhaps falling to 170-180 as the week progresses. We hesitate to say this, but geomagnetic conditions are predicted to be good once we get past the disturbances on the 28th and the 1st, but only time will tell! And now the VHF and up propagation news from G3YLA and G4BAO There is likely to be a welcome return of high pressure for much of the period from this weekend until the middle of the coming week on the 5th of March. Models show a return of unsettled Atlantic weather, meaning lows, fronts, showers and rain scatter for the GHz bands. Until then, it will be typical high-pressure Tropo conditions with an extensive temperature inversion aloft caused by the descending warming air in the high-pressure region. This should provide ducting conditions over a large part of the country. As often, the far north of the UK will probably just miss out and retain too much breeze for the inversion to be effective. The lull in meteor shower activity continues, so once again your best chances will be in the morning hours around, or just before, dawn. The Sun has kept aurora seekers busy and shows how frequently it can just tip into the right disturbed conditions at this stage of the solar cycle. As we said earlier, there have been reports of visible aurora in the past week. The signs for this are the Kp index rising to five or greater and flutter on LF band signals or trans-polar paths on the HF bands. The new Sporadic-E season is almost upon us, but we are not there yet. Check the graphs on Propquest for signs of enhanced foEs values and check the HF bands first; 10m is particularly good for strong European Es signals. EME conditions will be predictable as usual, with Moon declination rising all week and path losses at their minimum at perigee late on Saturday the 1st of March. 144MHz sky noise is low from this coming weekend, rising to moderate by Friday the 7th. And that's all from the propagation team this week.

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

On this episode, special counsel Mike Dover and senior associate Jenny Wainwright discuss some of the key points from two items released by the FCC on August 29. The first is the FCC's latest action in the 5G Fund proceeding. The second is related to new rules to enable drone operations in the 5 GHz band.

Foundations of Amateur Radio To get into the hobby of amateur radio is easy, but that doesn't mean it's simple. I was introduced to the hobby three times. The first time I was a Sea Scout in the Netherlands. It was JOTA, the annual Jamboree On The Air and radio amateurs across the planet were set up at various Scouting locations with their stations showing off how to make contact with far away places. My memory of it is brief. I recall a green heavy army tent with radios on a table. There was noise everywhere. I was told that I was hearing a station in Brazil, which seemed incongruous, given that I was standing on an island surrounded by other Sea Scouts, a place where I had been camping and sailing for several years. We trooped out of the tent and ten minutes later I broke a finger playing a game where you sat on a mast trying to upend the other person using a canvas bag with a jib in it. I was unceremoniously upended and landed poorly and broke the middle finger on my right hand. Being a teenager that was of course a source of immediate ridicule and innuendo and getting a dink, that's Aussie slang for getting a ride on the back of the pushbike of my boatswain to the local hospital, after rowing from the island to the mainland caused me to completely forget that amateur radio experience. The second time I came across the hobby was through my then manager, Ian, whom I now know as VK6KIH, but at the time he was a quiet spoken man thrust into the role of manager. The introduction came in the form of a Daihatsu Charade with a massive, what I suspect, was a 40m HF whip. The amateur radio aspect made little or no impression. The antenna, clearly much too large for such a tiny vehicle, did. I don't recall ever talking about amateur radio or even seeing his setup. Come to think of it, I'm not sure if I ever have. The third time I came across the hobby was at a dinner table surrounded by fellow "dogcow" geeks. One of them, Meg, then with the callsign VK6LUX showed us her brand new shiny purchase, a drone, that could be controlled remotely via WiFi on 2.4 GHz. She went on to tell us that the range was pretty limited because it was WiFi, but because she was a radio amateur, she was going to experiment with an amplifier. This was permitted because as I learnt, the 2.4 GHz WiFi frequencies are shared with amateur radio. You might know it as the 13cm band. I asked about this thing called amateur radio. I wanted to know what was involved, how would you become one, what would it cost, you know, all the things everyone always asks. I was told that there'd be a course in two weeks with an exam the weekend after. I asked if we needed a group booking and was told to "just rock up". So I did. I got my license in 2010 and my world changed forever. I will add, just to make sure that if you're planning to do this, that during my course I discovered that my license wouldn't permit my use of the 13cm band, so I'd have to upgrade. I promptly purchased the requisite course material and started reading. In the mean time I got distracted by the activities at a local club, then I bought a radio, then I was told I wasn't a real amateur because I only had a beginners' license, so to prove a point, I started having fun with my license. I haven't stopped since. Now, some, or maybe all of this, I've shared before. Here's something new. I'm a so-called A.F.O.L, or an Adult Fan Of Lego. It's not a guilty pleasure, I'm happy to admit it. I have too much Lego around me. My oldest set is from 1964, House with Garage, number 324-2. It's not complete any longer, the car is long gone, the garage door weights are broken off, but it has pride of place in my living room. History does not reveal how I came into possession of it. Best I can reconstruct is that in the deep dark corners of Australia it takes a little while for kits to arrive, since I was born after the kit came into existence. I do know that I had it before 1976. The other day I was watching a documentary about Lego and one thing stood out to me. I'll share the entire quote by Kjeld Kirk Kristiansen the then President and CEO of The Lego Group: "During the 1990s, we kept thinking that much more should be done for the adult "hobbyist builders," as we called them at the time. Most people on the management team thought we should concentrate on children instead, but I felt that a person could have an inner child at any age." Why this is important is because of my activities as a radio amateur. We as a community keep saying that we should grow, that we're losing too many people, that we need to engage with S.T.E.M., or Science, Technology, Engineering and Mathematics. Whilst that may be true and whilst JOTA and Scouting might give us exposure to fresh new people, there's a massive community of adults who already know about our hobby. They just don't yet know how it might interact with them, personally, or how they might find it interesting, or engaging, rewarding, and all the other things that you as an amateur already know about. So, if there's Adult Fans Of Lego, why not Adult Fans Of Amateur Radio? While thinking about that, how would you talk to them, how would you go about finding them, relating their interests to our hobby, finding common ground and discovering even more things that we can add to the thousands of amateur activities we already know about?

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.

Have you heard of the Schumann Resonance? Want to know how we can combat the effects of EMF through sound and frequency? Ready to get your mind blown on how humans are electrical beings? Tune in to this jam packed episode all about EMF, how we are human antenna connected to a magnetic grid, and how sound and resetting with the earth's frequency can heal.    In this episode, we will discuss the fact that humans are electrical beings. We transmit and receive electromagnetic energy from natural sources; plants, animals, people, and the earth, but many of us are robbed of this connection. We will discuss how smart devices, EMF, Wifi, and wearables are hijacking our frequency and what we can do to tap back in.    Also in this episode:  Episode 364 All About EMF with guest Theadora Scarato of Environmental Health Trust The Body Electric - Robert Becker What is EMF and Why is it Concerning?
