Foundations of Amateur Radio Since becoming a licensed amateur in 2010, I have spent a good amount of time putting together my thoughts on a weekly basis about the hobby and the community surrounding amateur radio. As you might know, my interest is eclectic, some might say random, but by enlarge, I go where the unicorns appear. Over a year ago I mentioned in passing a community called HamSCI. The label on the box is "Ham Radio Science Citizen Investigation", which gives you a sense of what this is all about. It was started by amateur radio scientists who study upper atmospheric and space physics. More formally, the HamSCI mission is the "Continuation and extension of the amateur's proven ability to contribute to the advancement of the radio art." If you visit the hamsci.org website, and you should, you'll discover dozens of universities and around 1,300 people, many of whom are licensed radio amateurs, who are asking questions and discovering answers that matter to more than just our amateur community. For the eighth time the HamSCI community held an annual "workshop", really, an opportunity to get together and share ideas, in person and across the internet, a conference by any other name. Under the banner theme of "HamSCI's Big Year", over two days, 56 people representing 27 different organisations across 61 sessions, tutorials, discussions, tours, posters and demonstrations, explored topics all over our hobby, from the Personal Space Weather Network, capable of making ground based measurements of the space environment, to the Whistler Catcher Pi, a project to record the VLF spectrum to 48 kHz using a Raspberry Pi. You'll find research into HF antennas for the DASI or Distributed Array of Small Instruments project and associated NSF grants, exploring measurements of HF and VLF, combined with GPS and magnetometer across 20 to 30 stations. There's discussions on how to explore Geospace Data, such as information coming from the Personal Space Weather Station network, or PSWS, using the OpenSpace project and dealing with the challenges of visualising across a wide scale, all the way up to the entire known universe. Did I mention that there's work underway to add PSWS compatible receivers to Antarctica? There reports on observations and modelling of the ionospheric effects of the April 2024 solar eclipse QSO party, including Doppler radio, HF time differences, and Medium Wave signal enhancements, not to mention planning and promoting future meteor scatter QSO parties. There's, post-sunset sporadic-F propagation, large scale travelling ionospheric disturbances, GPS disciplined beacons, the physical nature of sporadic-E propagation and plenty more. As you might have heard me say at one time or another, the difference between fiddling and science is writing it down. It means that you'll find every session has accompanying documentation, charts, graphics and scientific papers. Remember, there's eight years of reading to catch up with, or learn from, or play with. The publications and presentations section on the hamsci.org website currently has 526 different entries. You might not be interested in the impact of radio wave and GPS scintillation, or rapid fluctuation in strength, caused during the G5 geomagnetic storm that occurred on the 10th of May 2024, or a statistical study of ion temperature anistropy using AMISR, or Advanced Modular Incoherent Scatter Radar data .. or you might. In case you're curious, "anistropy" is the property of being directionally dependent, in other words, it matters in which direction you measure, which might have some relevance to you if you consider that we think of the ionosphere and radio paths being reciprocal. If it reminds you of isotropy, that's because they're opposites. The point being, that amateur radio is a great many things to different people. If you're a scientist, budding, graduate or tenured, there's a home for you within this amazing hobby. I'm Onno VK6FLAB

GB2RS News Sunday the 24th of November   The news headlines: The past and the future – the RSGB releases more Convention presentations RSGB Tonight@8 on HF antennas – join the last live event of 2024 Encourage youngsters on the air during YOTA Month   The RSGB continues to share some great presentations from its recent annual Convention. The two this week look back to the important history of amateur radio and contrast that with how amateur radio might be influenced by modern technology. Don Beattie, G3BJ discussed the very different amateur radio environment of 1924, and the history and events of October that year when the first two-way trans-global radio communication between the UK and New Zealand took place. This centenary celebration is just one of a range of activities that have included RadCom articles and a re-enactment of the contact at Mill Hill School. In his presentation on using AI to write simple amateur radio applications, RSGB Board Chair Dr Stewart Bryant, G3YSX considers how using AI software can improve productivity and bring the ability to write effective software within the reach of more people. This presentation is being released separately as part of the RSGB's focus on encouraging coding and programming activities amongst the amateur radio community. You can find a range of coding resources on the RSGB website at rsgb.org/coding  To watch both presentations, go to the RSGB YouTube channel and choose the ‘RSGB 2024 Convention' playlist. The final RSGB Tonight@8 webinar of 2024 is on Monday the 2nd of December. The presentation by Tim Hier, G5TM will focus on the various HF antennas available for portable operating. He will also look at how to use very basic modelling software to ascertain the choices you have at your disposal. Tim's ethos when working portable is simple, “Five minutes from arrival to operating and no more”. Tim is also the editor of RadCom Basics and will refer to content in that RSGB publication that will help radio amateurs who want to try portable operating. Watch the webinar live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat. To find out more go to the RSGB website at rsgb.org/webinars Youngsters on the Air Month begins one week today. Callsign GB24YOTA will be active for the month, hosted by a range of groups, clubs and individuals. Marlborough Scout Group will be the first team of youngsters to operate. They will be on the air before midday on Sunday the 1st of December, and then again after 6 pm on the same day. Also operating the special callsign next Sunday will be the Cambridge University Wireless Society. They will be hosting the callsign between 12 pm and 6 pm. Remember to listen out and have a QSO with a young radio amateur on the air. If you'd like to get involved, you've still got time. Go to QRZ.com  and search for GB24YOTA to check availability and then email Jamie, M0SDV at yota.month@rsgb.org.uk to register your interest.  The RSGB VHF Contest Committee is currently planning the rules for the 2025 VHF contests. Following some discussion at the RSGB Convention, the committee members have some questions on which they would appreciate feedback from contestants, with particular topics focused on VHF Field Day and the Back Packers events. You can find the survey online at tinyurl.com/VHFCC2025 and it will close on Friday the 6th of December. Members of Wokingham u3a Amateur Radio Group have secured a new club call sign, G5UTA. The group operated the callsign for the first time during the national u3a week in September. G5UTA can be used by any u3a member with a Full licence, in support of a u3a event or demonstration. You can read more about the new callsign, including how to apply for authorisation to use it, in the January 2025 edition of RadCom. To find out more about amateur radio as a subject area within u3a, you can contact its new subject adviser Paul, G0NDN via the u3a website at tinyurl.com/u3asubjects The historic VLF transmitter at Grimeton Radio Station in Sweden is celebrating one hundred years since it was put into commercial operation. The unique Alexanderson alternator operates using callsign SAQ. To mark the centenary a special transmission will take place at 1000UTC on Sunday the 1st of December using CW on 17.2kHz. The event will be livestreamed on the organisation's YouTube Channel using the handle @AlexanderSAQ.

QSL via F5GSJ, Logbook of the World or ClubLog OQRS. Now the contest news The CQ World Wide DX CW Contest started at 0000UTC on Saturday the 23rd of November and ends at 2359UTC today, Sunday the 24th of November. Using CW on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ Zone. The UK is in Zone 14. On Tuesday, the 26th of November, the RSGB SHF UK Activity Contest runs from 1930 to 2230UTC. Using all modes on the 13cm, 9cm, 6cm and 3cm bands, the exchange is signal report, serial number and locator. On Wednesday, the 27th of November, the UK and Ireland Contest Club 80m Contest runs from 2000 to 2100UTC. Using CW on the 80m band, the exchange is your six-character locator. On Thursday, the 28th of November, the RSGB 80m Autumn Series CW Contest runs from 2000 to 2130UTC. Using CW on the 80m band only, the exchange is signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 21st of November. We've had yet another week of relatively calm geomagnetic conditions. The solar flux index has been in the 160s and despite having 14 M-class solar flares over seven days, we haven't had any coronal mass ejections to contend with. As a result, the daytime maximum usable frequency, or MUF, over a 3,000km path has been high, reaching more than 35MHz at times. The MUF declines after sunset, as expected, settling at about 12-13MHz, meaning the only HF band open to DX has been the 10MHz or 30-metre band. DX this week has included 3D2Y in Rotuma. This Pacific DXpedition has been spotted in Europe, on 20m, 15m and 17m CW, so plenty of choice as to which band you try. E51SGC in Rarotonga on the Cook Islands has also been spotted across many of the HF bands, but they will be leaving on the 24th of November. The good news is that the team of Stan LZ1GC and Ted LZ5QZ are moving on to Tonga as A35GC from the 25th of November until the 7th of December 2024. Gerben (PG5M) is active on the Falkland Islands as VP8G and has been spotted on 20m, 15m and 10m CW. He is there until the 25th of November so get in quickly! Next week, NOAA predicts that the SFI may rise to the mid-250s again. Geomagnetic conditions are largely predicted to be good, although do keep an eye on solarham.com for updates. And don't forget the CQ Worldwide CW contest this weekend which should bring a lot of DX to the HF bands. And now the VHF and up propagation news from G3YLA and G4BAO. The weather is now in an unsettled phase with areas of low pressure bringing alternating spells of mild wet and windy weather interspersed with colder brighter and breezy showery weather.  This raises a couple of radio-related points; one is that we will see some very strong and potentially damaging winds in some areas, so check daily forecasts and make sure your mast guys are secure; and secondly an absence of any marked high-pressure Tropo weather.  Rain and snow scatter may be worth checking on the GHz bands in such unsettled weather. Meanwhile, meteor scatter is worthy of greater attention as next week's list of showers includes the small Alpha Monocerotids shower and the tail end of the big Leonids shower.   This introduces another potential nugget of interest in that it is widely accepted that meteors form the source material for Sporadic-E. Despite being out of season in the traditional sense, the prevalence of stronger jet streams in unsettled weather makes the next week a possible ‘watch period' for Es. If you are curious about what these might look like, check out the propquest.co.uk  website and look for the near vertical incidence skywave or NVIS tab for Wednesday the 20th of November 2024. During the two events in the middle of the day and evening, the critical frequency of the Es layer reached values of nearly 10MHz, which could equate to four-metre propagation on a good day. You will see the Es blog tab upper air charts also show a jet stream of greater than 100 knots.  For EME operators, the Moon has passed peak declination so Moon availability and peak elevation will be falling. Path losses are high and rising towards apogee on Tuesday the 26th. 144MHz sky noise is low all week. And that's all from the propagation team this week.

Making Waves Day 2 The Conference for Creative Use of the Radio Spectrum in Open Systems, that brings users of the radio spectrum together. For over a century, technology has made it possible to transfer more data, faster, further. Today, wireless technology is everywhere and commonplace. However, it remains a playground and a ground for innovation for many communities. The spectrum24 conference provides an opportunity to publicize projects and to allow the different communities that use the spectrum to meet in person over a weekend. M17 Let's start the day off with a talk with Morgan Dieport ON4MOD from the M17 Protocol. M17 is a community of open source developers and radio enthusiasts. We're building understandable systems in support of the hackers and experimenters' history of ham radio. OpenRTX Silvano Seva IU2KWO OpenRTX is "Free and Open Source Firmware for Digital Ham Radios. Top-down designed with modularity, flexibility and performance in mind." The code is available on github. RF Swift We next caught up with Sebastien Dudek who had just presented a talk about the project Introducing our Go and shell script-based toolbox, designed to streamline the deployment of Docker containers for your preferred RF tools. This evolving toolkit promises even more features in the near future, making it an essential asset for RF enthusiasts. VLF receivers design The say that in Space no one can hear you scream, but here at spectrum24 I'm not so sure. The talk from Thierry Alves F4EOB, CT2JTZ spoke of listening to cosmic wind. So how low can you go ? Head over to http://www.vlf.it to find out. trx-control What do you do when you're not organizing conferences ? Hacking a project to contrail radios, and a lot more besides, using Linux. trx-control is a modern and extensible software system for Linux to control transceivers and other devices over the network. It can as well be used to integrate third-party applications or databases.

Foundations of Amateur Radio If you've heard the phrase "shortwave listeners", you might have wondered what on earth that was all about. It relates to the length of a radio wave used to transmit information. The length of a radio wave is tied to its frequency. The longer the wave, the lower the frequency. When radio amateurs talk about bands, like for example the 40m band, we're talking about a range of frequencies where the wavelength is around 40m. From a frequency perspective, this is around 7 MHz. The 160m band, at about 1.8 MHz, or 1,800 kHz is considered the beginning of the short wave bands. This implies that there are longer waves as well. If you've ever seen or owned a mid 1980's transistor radio, you'll have seen the notation MW, which stands for Medium Wave, today it's called the AM band. Older radios might have the notation LW, or Long Wave. The medium wave band is a broadcast radio band that runs between about 500 and 1,700 kHz. The wave length is between 600 m and 170 m. When radio was still in its infancy, there was also a popular long wave band, with wavelengths between 800 m and 2,000 m, or 150 to 375 kHz. Today much of that has gone by the wayside. With the advent of digital radio, in Australia it's called DAB+, Digital Audio Broadcasting, the whole idea of "wave" has pretty much vanished. Some countries like Japan and the United States are in the process of discussing the phasing out of the AM broadcast band. Much of that appears to be driven by car manufacturers who claim that the AM band is no longer useful or used, but forget to tell anyone that they really want to stop having to put AM radios in their cars because it's difficult to isolate the electrical noise from their modern contraptions in order to make it possible to actually listen to that band. If you ask me, it's a good incentive to make electronics RF quiet, something which is increasingly important in our wirelessly connected world. This might lead you to believe that all activity on air is moving to higher and higher frequencies, but that's not the case. The properties that made long wave and medium wave radio possible in the early 1900's are still valid today. For example, there are WSPR or Weak Signal Propagation Reporter beacons on the 2200m band, or at 136 kHz. Whilst your RTL-SDR dongle might not quite get down that low, most of them start at 500 kHz, you don't need to spend big to start playing. My Yeasu FT-857d is capable of tuning to 100 kHz, plenty of space to start listening to the 2200m band, even if I cannot physically, or legally, transmit there. If you want to build your own receiver, you can check out the weaksignals.com website by Alberto I2PHD where you'll find a project to build a receiver capable of 8 kHz to 900 kHz using a $50 circuit board. If that's not enough, there's radio experimentation happening at even lower frequencies. Dedicated to listening to anything below 22 kHz, including natural RF, with a wavelength greater than 13 km, Renato IK1QFK runs the website vlf.it where you'll find receivers and antennas to build. Given that most sound cards operate up to around 192 kHz, you can start by connecting an antenna to the microphone port of your sound card and use it to receive VLF or Very Low Frequencies. On your Linux computer you can use "Quisk" to tune. There are VLF transmitters on air. For example, SAQ, the Grimeton Radio Station in Sweden opened on the 1st of December 1924. Capable of 200 kW, today it uses about 80 kW and transmits twice a year on 17.2 kHz. While we search for higher and higher frequencies, there is still plenty of fun to be had at the other end of the radio spectrum. Consider for example that VLF or Very Low Frequency radio waves, between 3 and 30 kHz can penetrate seawater. I'll leave you to explore. I'm Onno VK6FLAB

Atha Energy CEO Troy Boisjoli joined Steve Darling from Proactive to announce announced the completion of equipment and supply mobilization to the Angilak project in Nunavut, Canada. The mobilization effort included the delivery of two state-of-the-art X10 Diamond Drills, aimed at enhancing daily meterage production compared to previous drilling campaigns. Scheduled to commence in early June 2024, Atha Energy has finalized a service agreement with Base Diamond Drilling, a renowned operator with extensive experience in Canada's northern regions and uranium-rich Athabasca Basin, to conduct a Phase I diamond drilling program. Angilak, wholly owned by Atha Energy, hosts the Lac 50 uranium deposit, one of the largest high-grade deposits outside of the Athabasca Basin, boasting a historical mineral resource estimate of 43.3 million pounds at an average grade of 0.69% U3O8. The 2024 exploration program at Angilak aims to advance geological understanding and delineate additional mineral resources, building upon the groundwork laid by Latitude Uranium, acquired by Atha Energy in late 2023. Phase I of the program will feature a nearly 10,000-meter diamond drilling campaign targeting the expansion of the Lac 50 Deposit, which remains open in all directions. Phase II will encompass geophysical surveys, including electromagnetic, magnetic, and VLF surveys, alongside ground geochemistry sampling and mapping, further enhancing the project's exploration efforts. #proactiveinvestors #athaenergycorp #cse #sask #otcqb #saskf #minung #uranium #UraniumMining, #Nunavut, #DiamondDrilling, #PhaseOne, #AngeliqueProject, #LatitudeUranium, #92Energy, #UraniumExploration, #MiningNews, #Geology, #EnergyResources, #NaturalResources, #EnvironmentalImpact, #SustainableMining, #ResourceManagement, #EconomicDevelopment, #InvestmentOpportunity, #CorporateStrategy, #IndustryLeaders #invest #investing #investment #investor #stockmarket #stocks #stock #stockmarketnews

Using all modes on the 6m band, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of April 2024 Looking at the Sun on Wednesday the 3rd of April, you might be forgiven for thinking we are near sunspot minimum! With a near-total lack of sunspots and a solar flux index of 112, the solar disk was looking pretty bare. Compare that with just two weeks ago when the solar flux index was sitting at 209 on the 23rd of March. But never fear, there seems to be some activity coming up. Two active regions, AR3627 and AR3628, have just rotated into view, but in the meantime make the most of the geomagnetically-quiet conditions. 10m propagation is still holding up, although you may find that the band opens a little later in the morning and shuts earlier in the afternoon. The 4X6TU and VK6RBP IBP beacons were both audible at 0945UTC on Thursday the 4th, while China, Japan, Mongolia and Thailand were copiable on 10m FT8, even with a lowish solar flux index. Higher HF band propagation from the UK has moved from favouring North America to north-south paths, notably to South Africa and South America. Next week, NOAA predicts that the solar flux index will rise a little, perhaps starting at around 135 and finishing at around 150. Geomagnetic conditions should be reasonably quiet with a maximum Kp index of 3, unless we get a coronal mass ejection that could send it soaring. As always, keep an eye on solarham.net  for current conditions. And now the VHF and up propagation news from G3YLA and G4BAO There have been reports of trans-equatorial QSOs on 144MHz from Southern Africa to the Southern Mediterranean, but here in the UK we can only dream due to our northerly location. The next period of weather is unfortunately shaping up to be the same as most of the recent ones, dominated by low-pressure systems driving active weather fronts across the British Isles. It means that Tropo conditions seem unlikely to feature much through to the end of the coming week. Rain scatter for the GHz bands remains the mode of choice with help from some heavy April showers. Meteor scatter options are still best with random meteors before dawn, but we are getting closer to the April Lyrids shower later this month, so not long to wait now. The solar conditions have subsided a little recently, but we remain in scope for further activity, especially since April can be one of the more active months for Aurora. Watch out for fluttery signals on HF or VHF bands, use the various clusters, or save the frequency of one of the northern beacons in your rig's memory. This is a good time to suggest updating your list of favourite beacons on the 10, 6, 4 and 2m bands since they'll be useful for the upcoming sporadic-E season too. It's a good time to take an early look at the sporadic-E prospects before it gets properly busy.  Some background rules which may help are to use propquest.co.uk to see where the jet streams are since Sporadic-E propagation is often associated with turbulence in regions of jet stream activity. Then look for a relatively low Kp index. The other main rules are related to timing. Usually, there are two windows of opportunity, one in the morning and a second in the late afternoon or early evening. However, at the beginning of the season, these are approximate.  Sporadic-E starts on the lower bands like 10m and, if strong enough, will gradually extend to the higher bands. The 10 and 6m bands are probably the ones to check this month. For EME operators, Moon declination goes positive again on Sunday, which is also Moon perigee, its closest point to Earth, so we'll see lengthening Moon windows, increasing elevation and low path losses. 144MHz sky noise is low until Monday's total solar eclipse, then moderate for the rest of the week. And that's all from the propagation team this week.

Atha Energy CEO Troy Boisjoli joined Steve Darling from Proactive to unveil the ambitious plans for the company's 2024 Exploration Program, particularly focusing on the Angilak Project in Nunavut and its projects in the Athabasca Basin. At the Angilak Project, Atha Energy is gearing up for an intensive diamond drilling campaign as part of its phase one program, scheduled to kick off in June 2024. The primary objective of this phase is to expand the Lac 50 Deposit, a promising asset that exhibits openness in all directions. With 10,000 meters of diamond drilling earmarked for this phase, the company aims to not only enhance the existing deposit but also unearth potential new discoveries within the vicinity. Furthermore, exploration drilling will be directed towards high-priority targets on parallel structures to Lac 50, previously identified as prime candidates for hosting uranium mineralization. Looking ahead to Phase II, Atha Energy will embark on a comprehensive airborne geophysics program encompassing electromagnetic, Mag, and VLF survey types. This phase will be complemented by targeted ground geochemistry sampling and mapping activities. The overarching goal of Phase II is to pinpoint and de-risk a pipeline of additional high-priority targets, setting the stage for future exploration endeavors. Meanwhile, in the renowned Athabasca Basin, Atha Energy is set to advance nine of its 100%-owned projects through a combination of ground and airborne geophysical surveys. By leveraging these techniques, the company aims to deepen its geological understanding across each project, thereby increasing the likelihood of making significant discoveries while optimizing capital expenditure for future drilling campaigns. Notably, Atha Energy's exploration efforts in the Athabasca Basin will be further augmented by the incorporation of projects such as Gemini, pending the completion of the proposed scheme of arrangement with 92 Energy Limited. Gemini, which boasts the recently discovered high-grade GMZ showing, holds immense promise and will be seamlessly integrated into the company's broader exploration program. Atha Energy intends to provide a comprehensive update, including detailed drilling plans for the Gemini project, following the successful conclusion of the transaction. #proactiveinvestors #athaenergycorp #cse #sask #otcqb #saskf #minung #uranium #UraniumExploration, #AngleACC, #NunavutMining, #DiamondDrilling, #GeophysicalSurveys, #ResourceExpansion, #HighGradeUranium, #MiningInCanada, #EnergySector, #NuclearEnergy, #SustainableMining, #ExplorationTechnology, #MineralExploration, #UraniumMarketTrends, #AthabascaBasin, #92EnergyDeal, #GeminiProjectExploration, #DMZZoneUranium, #InvestingInUranium, #CleanEnergy, #NuclearFuel, #EnvironmentalMining, #InnovativeExploration, #ResourceSector #invest #investing #investment #investor #stockmarket #stocks #stock #stockmarketnews

East Coast Host Gary K4AAQ had volunteered to do radio at a local Christmas parade. As he was lacing up his sneakers, about to leave home, wife Cyndi KD4ACW called to dispatch him to the hospital where mom had been taken with chest pains. Gary had planned to do some video and interviews at the event for today's show. Instead Gary and West Coast Host David W0DHG talk about how to weigh conflicting obligations to family and community (and Podcasting). (Mom didn't have a heart issue, but it was still something serious. She's OK now)David also had comments on how his favorite event, the Baker to Vegas charity run, has decided to replace ham radio with communications from Verizon (while still urging them to volunteer for other jobs). There's more to that story, and it's not isolated to that event. The MS Society is using ham radio less for smaller, more urban walks. And in the Emcomm arena, Auxcom leaders have been saying that hams should be cross-trained for communication on other systems. That's something to dig into on a future show.Meanwhile, we noted that the new FCC rule dropping the data-rate restriction of ‘300 baud' on the HF bands, replacing it with a 2.8 kHz bandwidth limit, has finally been published in the Federal Register, and will take effect on January 8, 2024. So not quite the Christmas present we expected, but Happy New Year! And a FNPRM (Further Notice of Proposed Rulemaking) clock is ticking for comments on how to handle data rate/bandwidth of the VLF, VHF and UHF bands. That spectrum is not covered by the new HF data bandwidth rule. Finally, no news on the Netflix Watch.

The Kp index hit 6.67 on the 19th of September, spawning reports of visible aurora from around the UK once again. This was the result of a coronal mass ejection passing Earth, which caused a period of strong G3 storming very early that morning. The ionosphere was badly affected with MUFs over a 3,000km path down below 18MHz for most of the day. By Wednesday the 20th, things began to improve and MUFs were back to 21MHz, and sometimes even 24MHz, by late morning. By Thursday the 21st, the Kp index was down to 2.67. Meanwhile, we had numerous C- and M-class solar flares to contend with as well – a total of 39 from the 18th to the 20th. So, last week was not exactly a good time for HF operations! This week, commencing today the 24th, NOAA predicts that the solar flux index will be in the range of 135 to 145 although, if the past month is anything to go by, it could easily be higher. The Kp index is forecast to be 2, apart from on the 28th and 29th when it could rise to 4. In reality, with so many sunspots, we could have a solar flare and associated coronal mass ejection at any time, so take these predictions with a pinch of salt! The good news is that we are now past the autumnal equinox, so the ionosphere is improving. Expect better worldwide HF conditions as we head towards October and November. And now the VHF and up propagation news The recent unsettled weather seems to have set a trend for us with a likely repeat process through the coming week, although there may be a few drier interludes. The next low in the sequence will soon be arriving to keep the rather unsettled theme in play. This means that rain scatter is a good choice for operators during the period. There is usually some uncertainty in such a complex pattern, and recent model runs have been alternating between a return of high pressure during the next week, with a chance of Tropo, and the continuation of lows with fronts bringing rain and showers. We are, however, in a ‘keep the lows coming' mindset at the moment, so don't build your hopes of Tropo too high. Such uncertainties in long lead-time forecasts are quite typical at this time of the year when ex-hurricanes can get involved in the Atlantic flow pattern and disrupt the forecasts very easily. The other modes to monitor are aurora, which has been seen recently from southern Britain, so definitely one to keep in mind, and meteor scatter, which can be productive. We are approaching the ‘busy season' for meteors with several good showers between early October and December. However, the last week in September does not hold much promise. There are always random meteors to keep interest alive, but this week might be better used getting equipment ready for the next few months of activity. Having reached its lowest declination of the lunar month, the Moon is now beginning its slow climb back up. With the Moon out of Sagittarius, sky noise will decrease and is at its lowest mid-week. Path loss, or degradation, will be lowest on the 27th with the Moon at perigee, its closest point to Earth. The full Moon is on the 29th. Altogether, it looks like a good week for EME operations, especially if you can elevate your antenna or dish reflector. And that's all from the propagation team this week.

Foundations of Amateur Radio Our community is full of TLAs, or three letter acronyms. Some of them more useful than others. For example, I can tell you thank you for the QSO, I'm going QRT, QSY to my QTH. Or, thanks for the chat, I'll just shut up and take my bat and ball and go home. Acronyms arise every day and it came as no surprise to spot a new one in the wild the other day, SHF. It was in a serious forum, discussing antennas if I recall, so I didn't blink and looked it up. Super High Frequency. Okay, so, where's that? I'm familiar with VHF and UHF and as radio amateurs we're often found somewhere on HF, that's Very High Frequency, Ultra High Frequency and High Frequency if you're curious. Turns out that the ITU, the International Telecommunications Union has an official list, of course it does. The current ITU "Radio Regulations" is the 2020 edition. It's great bedtime reading. Volume one of four, Chapter one of ten, Article two of three, Section one of three, Provision 2.1 starts off with these words: "The radio spectrum shall be subdivided into nine frequency bands, which shall be designated by progressive whole numbers in accordance with the following table." When you look at this table you'll discover it starts with band number four and ends with band number twelve, between them covering 3 kHz to 3000 GHz. In position ten you'll see the designation "SHF", covering 3 to 30 GHz, centrimetric waves. A couple of things to note. The list starts at band four. There are of course frequencies below 3 kHz. The list ends at twelve, but there are frequencies above 3000 GHz. You'll also note that I'm not saying 3 Terahertz, since the ITU regulations specify that you shall express frequencies up to 3000 GHz using "gigahertz". Interestingly the same document has a provision for reporting interference where you can report using Terahertz frequencies, so I'm not sure how the ITU deals with such reports. Another thing to note is that this table doesn't actually define what SHF means. It's nowhere in the radio regulations either, I looked. I'm not sure where the words Super High Frequency came from. There is an ITU online database for looking up acronyms and terms. That leads to a document called "Nomenclature of the frequency and wavelength bands used in telecommunications", which also doesn't use "Super High Frequency" anywhere. That said, using the ITU band four, where its definition starts, the VLF band, or Very Low Frequency, followed by LF, Low Frequency, MF, Medium Frequency, the familiar HF or High Frequency, VHF, UHF, then SHF and beyond that, EHF, Extremely High Frequency and THF or Tremendously High Frequency, yes, Tremendously High. There's a report called the "Technical and operational characteristics and applications of the point-to-point fixed service applications operating in the frequency band 275-450 GHz". It introduces the term "THF which stands for tremendously high frequency" but adds the disclaimer that "this terminology is used only within this Report." Seems that there are plenty of documents on the ITU website using that same definition, so I'm guessing that the cat is out of the bag. THF by the way is defined as being for 300 to 3000 GHz frequencies. By the way, the ITU TLA finder exposes that THF stands for Topology Hiding Function. Where's a good acronym when you need it? Speaking of definitions, I came across the definition of a "taboo channel" which according to the ITU is "A channel which coincides with the frequency of the local oscillator in the single super heterodyne receiver which is tuned to an analogue channel." Anyway, we still have a way to go. Below band four, less than 3 kHz, we have ULF or Ultra Low Frequency, SLF, Super Low Frequency and ELF, Extremely Low Frequency, which is defined as band one, between 3 and 30 Hz. Below that, some have suggested TLF, or Tremendously Low Frequency which apparently goes between 1 and 3 Hz with a wavelength between 300,000 down to 100,000 km. Others have suggested that this is an internet meme, but so far it seems to me that it has just as much legitimacy as any of the other wordings, since it appears that the ITU explicitly excludes such definitions, even if internal documents introduce terms from time to time. It did make me wonder, what comes after Tremendously High Frequencies, Red? Turns out, yes, well, infra-red pretty much follows on from Tremendously High Frequencies. If you think that's the end of it, think again. The IEEE, the Institute of Electrical and Electronics Engineers has its own definitions, of course it does. Unfortunately they decided that you need to pay for their standard. It was first issued in 1976 "to remove the confusion". There's an xkcd comic called "Standards", number 927 if you're looking. It goes like this: Situation: There are 14 competing standards. 14?! Ridiculous! We need to develop one universal standard that covers everyone's use cases. Yeah! Soon: Situation: There are 15 competing standards. Anyway, the IEEE designates that after UHF comes L or Long wave, followed by S, or Short wave, then comes C, the compromise between Short wave and X or cross or Exotic. Then there's Ku, Kurtz Under, K, Kurtz, and Ka or Kurtz above, Kurtz being the German word for Short. There's the V band and the W band which follows the V band. Had enough yet? NATO, the EU and the US define these using letters of the alphabet. And broadcasters use Band Numbers which link up to nothing in particular. I wonder if the measure of a society is just how many different ways can be used to describe the same thing. Perhaps we should have stopped at Hertz or Hz, which was established in 1930 by the International Electrotechnical Commission, as an expression of the number of times that a repeated event occurs per second, in honour of Heinrich Hertz. One more three letter acronym, the International Electrotechnical Commission is better known as the IEC. I wonder if the ITU is taking suggestions, ginormous, utterly, inordinately, awfully and humongously seem like perfect opportunities for future expansion. I'm Onno VK6FLAB.

Grimeton Radio Live, off-air, recording of a morse code (CW or continuous wave) transmission in English from station SAQ, Grimeton Radio, Sweden, on 16 November 2022 beginning at 16:00 UTC on a very low frequency (VLF) of 17.2 kHz. The signal originates from the historic Alexanderson alternator transmitter at Grimeton near Varberg on the southwest coast of Sweden, running at about 80 kW. The antenna is essentially omnidirectional.The transmitter was tuned up before the broadcast with many sequences of VVV VVV VVV DE SAQ SAQ SAQ being sent. The message, titled UNESCO 50th Anniversary Telegram, began at 16:00 UTC, lasted about 9 minutes and 30 seconds, and is as follows:CQ CQ CQ DE SAQ SAQ SAQQ THIS IS GRIMETON RADIO STATION SAQ IN A TRANSMISSION USING THE ALEXANDERSON 200 KW ALTERNATOR ON 17.2 KHZ.

K2 Gold Corp CEO Anthony Margarit joined Steve Darling from Proactive to share news the company has announced its plans for exploration at two key projets, the Si2 and Wels. Margarit telling Proactive the Si2 Project in Nevada will see 60 line-kilometers of ground magnetic surveys aimed to identify geologic structures. The company is also using a drone based orthophotogrammetry survey to generate a Digital Elevation Model. The Wels Project in the Yukon will also see a lot of work, Margarit says exploration plans for 2022 will focus on a ground magnetic-VLF survey over the Saddle, Chai, and Pekoe targets. They will also survey to the west to test a significant portion of the low-lying covered area.

Charlotte King is best known for her accurate prediction of the major eruption of Washington's Mt. St. Helens, May 18, 1980. She was a mere 12 minutes off. This prediction threw her into the limelight and attracted the attention of scientists and journalists alike, names like Human Seismograph and Incredible Ears soon found their way into print and soon she was seen on network and independent television shows. Doctors as well as the military were perplexed by her unusual ability to hear sounds in the ULF, VLF, and ELF ranges. She began hearing these sounds in mid-May 1976. Charlotte was tested in four states by the scientific and medical communities, and the tests revealed that she could hear in the under 10hz range. Further tests revealed specifically below 2-7hz. Thus was born what the doctors and the scientists who tested her coined "The Charlotte King Effect."

On Long Island, A Tribal Nation Faces Growing Pressures The Hamptons on Long Island are known as a mansion-lined escape for wealthy New Yorkers. But the area is also home to the Native residents of the Shinnecock Tribal Nation. An estimated 1,500 Shinnecock members are left in the U.S., and about half live on the Nation's territory on Long Island. As with the rest of the island, Shinnecock Nation is extremely vulnerable to climate change. Receding shorelines threaten to eat up three-quarters of its territory by 2050, adding to the existing threat of development from the Hamptons. This issue of climate change and its impacts around Long Island is the subject of the new podcast, “Higher Ground,” from WSHU Public Radio in Fairfield, Connecticut. One of the stories told in the podcast is that of Tela Troge, Shinnecock tribal sovereignty attorney and kelp farmer, who lives on Shinnecock territory in Long Island.  Tela talks to Ira about seeing climate change and development affect Shinnecock land with her own eyes, and her venture into kelp farming as a tool for nitrogen sequestration.      The World According To Sound: Listening To Lightning There is more than one way to listen to a bolt of lightning. While you can pick up the boom and rumble of thunder with your ears, if you tune in with a radio receiver, you can hear an entirely different sound: an earth whistler. When lightning strikes, it releases electromagnetic radiation in the VLF or Very Low Frequency band, which runs from 3 Hz to 30 kHz. This falls within the human range of hearing, which spans from 20 Hz to 20 kHz. However, we can not hear whistlers with our own ears because the radiation is electromagnetic, not physical vibrations in the air. We can, though, capture the electromagnetic radiation with a radio receiver. Radio operators have been picking up the strange twanging of lightning ever since they started trying to tune into man-made signals. They dubbed the eerie electro-magnetic disturbances in their headphones “earth whistlers.” People first heard earth whistlers back in the 19th century. The electromagnetic radiation from lightning interfered with telephone lines and crept into phone conversations. You'd be talking with someone and hear these bursts of energy, like little phone ghosts.  Today, we know earth whistlers are made by the interaction of lightning with the planet's magnetic field. There are over a million lightning strikes in the atmosphere, which means there is a nearly constant chorus around earth.  The whistlers in this piece were provided courtesy of NASA and The University of Iowa.  The World According to Sound is a live audio show, online listening series, and miniature podcast that focuses on sound, not story. Producers Chris Hoff and Sam Harnett create intentional, communal listening experiences as a way to “reclaim autonomy in a visually dominated world that is increasingly fracturing our attention.”  This recording is part of their next listening series, an immersive listening party where audiences from all over the globe will be invited to experience a world of sound together, beginning in January 2022. You can get a ticket to the series here.      Save The Wetlands, Save The World In Rising, the Science Friday Book Club pick for this fall, author Elizabeth Rush writes frequently of marshes. Rush explores the disappearing wetlands of Louisiana's hurricane-battered coast, the San Francisco Bay Estuary, Staten Island's newly abandoned flood zones, and other marshes around the country. But why, scientifically speaking, are wetlands such a feature of the conversation around coastal resilience to climate change and rising seas.  In a recording with a ‘live' Zoom audience, SciFri producer Christie Taylor speaks with wetland ecologists Marcelo Ardón and Letitia Grenier about the resilience and adaptability of marshland, how climate change and sea level rise threatens them, and why protecting and restoring tidelands is good for everyone.      Widening The Lens On A More Inclusive Science In 2012, the Obama administration projected that the United States would need to add an additional 1 million college graduates in STEM fields per year for the next ten years to keep up with projected growth in the need for science and technology expertise. At the same time, though, native Americans and other Indigenous groups are underrepresented in the sciences, making up only 0.2% of the STEM workforce in 2014, despite being 2% of the total population of the United States. Why are Indigenous people still underrepresented in science?   In this re-broadcast of the 2019 conversation, Ira speaks with astrophysicist Annette Lee and anthropologist Kim TallBear about the historical role of science and observation in Indigenous communities, and how Western scientific culture can leave out other voices. They also discuss the solutions: What does an inclusive scientific enterprise look like, and how could we get there?      This Weekend, Take Time For The Moon This Saturday marks International Observe the Moon Night, a worldwide astronomy education event encouraging people to take time to look at the moon—through a telescope, if possible. Around the world, astronomers will be setting up public telescopes and encouraging passers-by to take a look.  Dean Regas, astronomer at the Cincinnati Observatory, joins Ira to explain how to get in on the lunar-observation action. They also talk about other astronomical events, including the ongoing Orionid meteor shower and an upcoming partial lunar eclipse on November 19.

Perda de Massa Magra em Dieta Cetogênica Massa Magra X Massa Muscular Como mede a Composição corporal Comparativo entre Dieta Cetogênica(VLC) X Dieta Low Fat (VLF) X Dieta Insaturada (HUF) - https://pubmed.ncbi.nlm.nih.gov/16403234/ e https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1373635/ Perda de Massa Magra semelhante entre VLC e VLF. Menor em HUF. De onde vem a noção de que uma Dieta Low Carb favorece perda de peso? Perda de Glicogênio muscular e diminuição de volume (https://www.instagram.com/p/B92XU_NFjop/?utm_source=ig_web_copy_link) Estudo Turkey Adaptações Metabólicas a uma Dieta Cetogênica: Substrato primário para Gliconeogênese são os aminoácidos. Mas a mobilização de gordura é acelerada, produzindo cetonas. Essas cetonas causam economia de glicose pelos tecidos que dependem desse açúcar. Então esses órgãos derivam sua energia indiretamente da gordura. Células glicolíticas (hemácias e medula renal) ainda precisaram de glicose. Mas produzirão ácido láctico que será reestabelecido em glicose no fígado (Ciclo de Cori). O fígado por sua vez utilizará energia das gorduras para refazer essa glicose. Portanto, até mesmo essas células usam indiretamente a gordura como fonte de energia. Diversos estudos corroboram a manutenção de massa magra em uma dieta Cetogênica devido a adaptações metabólicas (https://www.instagram.com/p/B2U7KloF2sf/?utm_source=ig_web_copy_link) Dieta Cetogênica ajuda na manutenção de Massa Magra em idosos (https://www.instagram.com/p/CEY4TJChTq5/?utm_source=ig_web_copy_link) Dieta Cetogênica melhora a composição corporal em atletas (https://www.instagram.com/p/B5AHeE6l-XP/?utm_source=ig_web_copy_link) Mecanismos de manutenção de Massa Magra Aumento da Adrenalina: Adrenalina inibe proteólise. Os corpos cetônicos exercem uma influência restritiva na degradação da proteína muscular. GH é um hormônio anabólico protéico e estimula a síntese protéica muscular. Como o baixo nível de açúcar no sangue aumenta as secreções de GH, pode-se especular que um VLCARB aumenta os níveis de GH. Além disso, observa-se um aumento da secreção de IGF-1 pelos músculos o que pode aumentar a incorporação de proteínas Um VLCARB é quase sempre relativamente rico em proteínas Se houver treino de resistência, a Dieta Cetogênica pode aumentar a liberação de testosterona, o que, por sua vez, pode manter ou aumentar massa muscular. (https://www.instagram.com/p/CCGKeq9lVMu/?utm_source=ig_web_copy_link) Conclusão: Uma dieta VLCARB protege contra a perda de massa magra desde que tenha o aporte necessário de proteínas. Aqui vale a pena diferenciar Dieta Cetogênica Terapêutica (Epilepsia) de Dieta Cetogênica Nutricional (Baixo Carbo, Média Gordura, Alta Proteína).

GB2RS NEWS Sunday the 17th of January 2021 The news headlines: RSGB publishes EMF Calculator New AllStar Gateway in North Lancashire Enter Construction Competitions! As agreed with Ofcom last month, the RSGB’s EMC Committee has published its EMF calculator, which incorporates the Ofcom calculator but adds a front end specifically for radio amateurs. It is currently an evaluation version, so the EMCC welcomes feedback to help it move towards a final one. You can download the calculator from the EMF page at www.rsgb.org/emf. Recently, the MB7IMB repeater came on the air in North Lancashire. It is a simplex AllStar gateway on 145.2375MHz narrow FM, with a CTCSS access tone of 110.9Hz. The North West AllStar Group has been formed, linking AllStar nodes and repeaters throughout north-west England. The group is encouraging the use of the repeater. All that’s needed is a standard 2m FM transceiver with CTCSS capabilities. If you have a node or gateway they welcome links to the system. The group has a Facebook page where you can find out more. Have you entered the RSGB’s ‘Get on the air to care’ construction competition? The deadline is the 1st of February. Your project can be hardware, software or a system and may be based on a kit. If you made something during the autumn lockdowns, over the holiday season, or are in the middle of something during the current restrictions, you could win £100 if you enter the competition. Send a short description of your project to gm.dept@rsgb.org.uk and include a few photographs, a video if possible and any related circuit diagrams. Whether you’ve just got your licence or you’ve been a radio amateur for years, you’re encouraged to take part. If you enter this competition you can also resubmit the same project to the 2021 RSGB Annual Construction Competition. Very low frequency enthusiast Joe, VO1NA reports that Stefan, DK7FC copied his 50-character EbNaut message transmitted from Newfoundland on 8.271kHz, with a radiated power of 10mW. We believe this is a new record for amateur transatlantic VLF. Joe’s tower supports a VLF rotated L, which is 10 metre average height and 100 metres long. The RSGB is delighted that 4,000 people have taken amateur radio exams via remote invigilation. This number covers exams at all three licence levels. We know that all radio amateurs will be encouraging as people progress and enjoy the diversity of amateur radio. Could you be the RSGB’s next President? Do you have the time and skills to serve on the Society’s Board of Directors? We’re into the final weeks of the nominations process for the RSGB elections, which will end at 2359UTC on the 31st of January. In addition to these two roles, there are three Regional Representative vacancies in Regions 2, 6 and 12. Each post-holder has indicated their willingness to stand for election but applications are also welcome from all RSGB Members living in these particular Regions. For more information visit www.rsgb.org/election. The results will be announced at the RSGB’s online AGM on Saturday the 24th of April. The Dayton Hamvention will not take place for a second year. Sponsored by the Dayton Amateur Radio Association, it was set to take place between the 21st and 23rd of May in Ohio. The committee said the show would return in 2022 and hinted at a QSO party for Hamvention weekend. The 80m RSGB National Radio Centre net continues to run each weekday at 10.30 am on 3.727MHz. The NRC volunteers have run 260 of these nets since March 2020 to support radio amateurs. They are keen for people to call in during the current lockdown. Get on the air and have a chat – they’d love to hear from you!   South Dublin Radio Club hosted Michael O’Connell from the I87 Astroshot Observatory to the club’s first online live lecture of 2021, via Zoom. The lecture is titled Amateur Observations of Meteors and is now available to view on the club’s YouTube channel. Michael’s presentation covers Meteors, Meteor related radio phenomena and how radio techniques are used by amateurs to detect and track meteors. Now the special event news Hull and District Amateur Radio Society is celebrating 100 years of amateur radio clubs in the Hull area with a year-long special event station, callsign GB1OOH. The station will operate most days throughout 2021 on bands ranging from 160m to 70cm and using different modes. Further details about the station and QSL options can be found on QRZ.com. During 2021, the British Railways ARS will be celebrating its 55th anniversary. They will be running the special event call GB0LMR, operated by BRARS member Mark, G1PIE from Preston in Lancashire. Bands of operation will be 40 to 10 metres using PSK-31, PSK-63 and SSB, plus VHF/UHF. Further information is on QRZ.com and www.brars.info. Now the DX news 4L1PJ is the callsign issued to Peter, 4L/G4ENL. He expects to operate SSB on various HF bands for the next few years while on work assignment in Svaneti, Georgia. QSL via N4GNR. Bo, OZ1DJJ will be active in his spare time as OX3LX from Tasiilaq Island, IOTA reference NA-151, until the 30th of January. QSL via Logbook of The World, Club Log’s OQRS or direct to OZ0J. Garry, 2M1DHG is active as ZC4GR from the UK Sovereign Base Area of Dhekelia for the next two and a half years. He operates SSB and digital modes on the 40, 20 and 10m bands, typically between 1700 and 1900UTC a few nights a week. QSL via EB7DX. Now the contest news Please remember to check before the contest for any new rules due to lockdown and social distancing, which may differ around the world. The RSGB strongly advises obeying your national and local government’s advice. On Tuesday the 1.3GHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes, the exchange is signal report, serial number and locator. On Thursday it’s the all-mode 70MHz UK Activity Contest. Running between 2000 and 2230UTC, the exchange is signal report, serial number and locator. Next weekend the BARTG RTTY Sprint runs from 1200UTC on the 23rd to 1200UTC on the 24th. Using the 3.5 to 28MHz contest bands, the exchange is simply the serial number. The UK EI Contest Club DX CW contest starts at 1200UTC on the 23rd and runs for 24 hours. Using the 3.5 to 28MHz contest bands, the exchange is signal report and District Code. Don’t forget, the UK Six Metre Group Winter Marathon runs until the end of this month. Just exchange a signal report and locator. Now the radio propagation report, compiled by G0KYA, G3YLA & G4BAO on Thursday the 14th of January. Well, no one predicted last week’s geomagnetic disturbance. In case you missed it, the Kp index rose to four on Monday the 11th January. This was caused by the arrival of an interplanetary shock wave from a coronal mass ejection on the Sun, which occurred on Thursday the 7th. NOAA had been predicting a settled Sun, which shows just how unpredictable our nearest star can be. The CME’s effects on the ionosphere were quite startling. The Chilton Digisonde data, as plotted at propquest.co.uk, shows that the predicted MUF over a 3,000km path dropped to below 14MHz by 1530UTC, although it did recover to more than 18MHz within an hour. That night there were widespread reports of visible aurora, but the ionosphere had recovered by Tuesday afternoon with the Kp index back to one by 1500UTC. Other than that element of ionospheric excitement there has been little to report, with the solar flux index down as low as 72 by Thursday the 14th with zero sunspots. The only other noteworthy event has been widespread winter Sporadic-E, which saw 12, 10 and six metres become wide open to Europe this the week. Next week, NOAA predicts that the solar flux index will remain in the mid to high 70s. The STEREO spacecraft show a coronal hole is about to rotate into view around the Sun’s eastern limb. The high-speed solar wind from this, and other polar coronal holes, may cause the Kp index to rise to four by Sunday the 17th and we may not see a recovery back down to two until the 21st. So it looks like the latter half of the week may be best for HF DX. And now the VHF and up propagation news. The current unsettled spell of weather should have taken a brief pause on Friday but may have returned this weekend, with an active front crossing the country, followed by a transient ridge in the second half of the weekend. These ridges are rarely good for widespread Tropo and the unsettled regime returns for the bulk of the coming week. Strangely enough, you can find temporary enhancements of Tropo conditions parallel to, and just ahead of, approaching weather fronts. It’s marginal but can make a difference to scores in the VHF/UHF UK Activity Contests. But GHz band rain scatter is probably a more reliable mode for the next week. The unsettled story also implies some strong jet stream activity, so it’s still worth a look at the usual Sporadic-E bands of 10m and 6m for one more week, although this is probably our last chance before the mode returns in force in April. Moon declination turns positive again on Tuesday, so we’ll have increasing Moon windows and peak Moon elevations this week. With apogee on Thursday though, path losses will be high. This trend of high declination and path loss only starts to reverse from May 2022, so get used to it! 144MHz sky noise is low. There are no significant meteor showers this week so continue to check pre-dawn for the best random meteor contacts. And that’s all from the propagation team this week.

In this episode of the Voices from DARPA podcast, John Waterston, a program manager since 2017 in the agency’s Strategic Technology Office, lets listeners in on his oceanic immersions both as a naval officer and a technology developer. Now a commander in the U.S. Naval Reserve, John offers snapshots of living, working, and serving on our nation’s nuclear submarines before describing his current work at DARPA to develop technologies to better understand, monitor, and navigate the planet’s most prevalent environment—the oceans. In one of his ambitious programs, John seeks to deliver what has been a coveted but elusive capability—the equivalent of GPS that operates even in the deep ocean. In a related program, John explains how very low-frequency (VLF) electromagnetic signals from lightning that occurs relentlessly around the world can become a key to a back-up positioning, navigation, and timing (PNT) system in case our must-have GPS goes down. And in perhaps his most audacious program, the Ocean of Things, he is assembling what amounts to an ocean-scale nervous systems comprising tens of thousands of floating sensors, opening pathways to an unprecedentedly fine-grained understanding of what is happening in vast ocean environments. Says John about the ocean, “it’s so immense, covering 70% of the Earth’s surface, yet even with all of the ships, all of the aircraft, all of the satellites, and all of the existing sensors, we are severely undersampling this environment.” He has made it his mission to fill in that data shortfall, which he says could significantly improve weather forecasting for the benefit of both military and civilian sectors.

Charlotte King is best known for her accurate prediction of the major eruption of Washington's Mt. St. Helens, May 18, 1980. She was a mere 12 minutes off. This prediction threw her into the limelight and attracted the attention of scientists and journalists alike, names like Human Seismograph and Incredible Ears soon found their way into print and soon she was seen on network and independent television shows.Doctors as well as the military were perplexed by her unusual ability to hear sounds in the ULF, VLF, and ELF ranges. She began hearing these sounds in mid-May 1976. Charlotte was tested in four states by the scientific and medical communities, and the tests revealed that she could hear in the under 10hz range. Further tests revealed specifically below 2-7hz. Thus was born what the doctors and the scientists who tested her coined "The Charlotte King Effect."Visit : www.thecharlottekingeffect.comEmail: charking@viser.netTelephone: 503-999-5745

C., Piispala, J., Kallio, M., Vayrynen, T., Huotari, N., Raitamaa, L., Kananen, J., Jarvela, M., Raatikainen, V., Borchardt, V., Kinnunen, H., Nedergaard, M., Kiviniemi, V. Abstract: Sleep is known to increase the convection of interstitial brain metabolites along with cerebrospinal fluid (CSF). We used ultrafast magnetic resonance encephalography (MREGBOLD) to quantify the effect of sleep on physiological (vasomotor, respiratory and cardiac) brain pulsations driving the CSF convection in humans. Transition to electroencephalography verified sleep occurred in conjunction with power increase and reduced spectral entropy (SE) of physiological brain pulsations. During sleep, the greatest increase in spectral power was in very-low frequency (VLF < 0.1 Hz) waves, followed by respiratory and cardiac brain pulsations. SE reduction coincided with decreased vigilance in awake state and could robustly (ROC 0.88, p < 0.001) differentiate between sleep vs. awake states, indicating the sensitivity of SE of the MREGBOLD signal as a marker for sleep level. In conclusion, the three physiological brain pulsation contribute to the sleep-associated increase in glymphatic CSF convective flow in an inverse frequency order.

GB2RS NEWS Sunday the 28th of June 2020 The news headlines: Online remote invigilation expanding Tonight @ 8: Antennas for small gardens New Propagation Studies video released The online remote invigilation of the UK Foundation amateur radio exam continues to be extremely popular, with over 800 successful candidates so far, and more than 650 already booked for future Foundation exams. The RSGB is now contacting candidates and Exam Secretaries who had previously booked for Intermediate exams before social distancing caused their postponement. Candidates will be offered online remote invigilation exam slots. It is hoped that bookings can also be opened to new Intermediate candidates in the near future, once existing bookings are cleared. Full exams will follow on in a similar manner in due course. The FAQ’s on the RSGB website, under the Training tab, will be updated shortly. The next RSGB Tonight @ 8 webinar is on the 29th of June and is a presentation on Antennas for small gardens by Steve Nichols, G0KYA. You can watch the live stream and ask questions on either the RSGB YouTube channel or the special Tonight @ 8 channel on the BATC website, https://batc.org.uk/live/RSGB. You can find out more about all the webinars at www.rsgb.org/webinars and you can also watch previous talks in the series at the same site. The RSGB has released a new VHF propagation video, created by the Society’s Propagation Studies Committee. You can watch this interesting presentation on the Society’s YouTube channel, www.youtube.com/theRSGB. The annual transmission by the 17.2kHz VLF Alexanderson Alternator will take place, as usual, this year on Alexanderson Day, Sunday the 5th of July. As usual, it will use the callsign SAQ. Startup and tuning begins at 0830 and 1130UTC, with the transmission of a message at 0900 and 1200UTC. You can watch both events live on their YouTube channel and, of course, listen out if you have VLF capability. Due to unforeseen circumstances, no RSGB awards information will be published between now and 22 July. If you have submitted your data for an award and have not yet received a reply, you will be contacted after that date. The Society would encourage you to keep working towards awards in the meantime – it is a great way to gain experience, especially if you’re new to amateur radio. You can find more details of the RSGB awards on the Society’s website, www.rsgb.org/awards. We understand that Bletchley Park plans to re-open on 4 July and have further details on their website, bletchleypark.org.uk. The RSGB National Radio Centre at Bletchley Park will remain closed, for the time being, but this will continue to be regularly reviewed. Due to uncertainty about large gatherings being allowed, and in recognition that many radio amateurs may not want to attend physical meetings for some time, the G-QRP Club took the unwelcome decision to cancel their Conventions for 2020. However, following a very successful survey of members, a meeting of the Standing Committee this week confirmed definitely that the G-QRP Convention for 2020 will take place as a virtual event, over the weekend of the 5th and 6th of September. There will be a series of webinars and possibly a virtual Buildathon. A small working group are now developing the detail and a number of key speakers have already volunteered. Full details will be shared as soon as they are known. Apologies to Tony, VK5ZAI for the error in his callsign last week. Tony received the Order of Australia in the Queen’s birthday honours list for significant service to amateur radio, particularly to satellite and space communication. The RSGB/NHS ‘Get on the air to care’ campaign continues to feature in the media across the world. Recently there were articles in the ARRL’s QST magazine and in the Emergency Services Times publication. You can see both on the Society’s media campaign web pages, www.rsgb.org/gota2c-media. The latest Something for the Weekend video goes out today on YouTube. ML&S looks back at the 1970s and the beginning of Amateur Radio Exchange with Bernie, G4AOG. Fund raising for Alzheimer’s Disease is part of the video. Go to https://youtu.be/fICqJM_BIfw. Now the special event news Since the change of regulations applying to special event stations in the UK, many activations are now able to go ahead. UK amateurs would like to thank Ofcom for their help in making this happen. Today, the 28th, is the Centenary of the Royal Corps of Signals. The Royal Signals Museum has a permanent special event callsign, GB100RSM, but due to the Covid-19 restrictions, they cannot run the station from the museum. The station will instead run from the home QTH of G3WZP in IO90BR. Activity will be until the end of June on the 40, 20 and 17m bands, using SSB and CW. Skeds are welcome. Another Royal Corps of Signals centenary station is GB100RS Royal Signals, operating from Bishop Auckland. It will start operating today, the 28th. Full details of the centenary stations and their operations can be found at https://rsars.org.uk/rsars-corps-celebrations-2020/. To commemorate their 3rd anniversary, special event stations will be on air during the FT8DMC Activity Days from the 1st to the 31st of July. All stations will bear the FTDMC or FTDM suffix, referring to the third anniversary of the FT8 Digital Mode Club. An FTDMC Anniversary Award can be earned by working the FTDMC and FTDM stations and collecting points applicable for various award classes. See www.ft8dmc.eu. Durham and District Amateur Radio Society is participating as one of the bonus stations in the 13 Colonies Special Event. GB13COL will run from 1300UTC on 1 July to 0400UTC on 8 July. The primary focus of the event will be the HF bands using SSB, CW, FM and various digital modes, but VHF and UHF will also be in use. This year’s QSL cards for GB13COL has been kindly sponsored by Martin Lynch at ML&S. Now the contest news Please remember to check before the events for new rules due to lockdown and social distancing, which may differ around the world. RSGB strongly advises obeying your own government’s advice first and foremost. The UK Microwave Group’s 5.7 and 10GHz bands contest runs from 0600 to 1800 today, the 28th. Using all modes, the exchange is signal report and serial number. Also today, the 28th, the 50MHz CW contest runs from 0900 to 1200UTC. It’s CW only and the exchange is signal report, serial number and locator. The 7MHz Cumulative contest runs from 1400 to 1600UTC today, the 28th. Using all modes, the exchange is signal report, serial number and locator. The 3rd 144MHz Backpackers contest is cancelled and there is a different format contest to replace VHF NFD, for 2020 only, called ‘lockdown VHF NFD’. Only single operator fixed stations may enter this contest. The rules are available at www.rsgbcc.org/vhf/rules/2020/VHFNFD.shtml. The rules are loosely based around the UKAC and VHF AFS rules and include a team element. The UK Six Metre Group’s Summer Marathon runs until the 2nd of August. Using all modes on the 50MHz band, the exchange is your 4-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Friday the 26th of June. After the recent excitement of a new Solar Cycle 25 sunspot, it seems the Sun has decided to go back to sleep. We have had zero sunspots since the 16th of June and the STEREO spacecraft Ahead view shows just one small bright area on the Sun, which might result in a spot in due course. Luckily, geomagnetic conditions remained quiet throughout the week, with a maximum Kp index of two. The bands were a little lacklustre, other than the continued Sporadic-E openings, which have brought almost daily fun on 28MHz. There were F-layer openings to be found on 14MHz, but these were mainly enjoyed by well-equipped stations. Ed, WA6QDQ/KH6 in Hawaii was audible at 0652TUTC on Tuesday the 23rd at G3UML’s Hendon QTH. As was William, AL7KC in North Pole, Alaska, who had a big pile up on 14.224MHz. Early morning does seem to be the best time to get on 14MHz, with Jim, E51JD on the South Cook Islands being reported again as well. But as the day goes on D-layer absorption grows and 14MHz doesn’t sound very lively at all. Fifteen metres was open to Brazil and Paraguay on Thursday afternoon, although this was mostly FT8. Otherwise, it was 10 metres and Sporadic-E contacts that continued to provide excitement, with one or two North American, South American and Caribbean openings occurring. Next week NOAA predicts more of the same, with a solar flux index hovering around 68-70 and a maximum Kp index of two. A weak solar wind stream flowing from a narrow coronal hole could reach Earth beginning on the 27th of June. A minor geomagnetic disturbance at higher latitudes may be expected. And now the VHF and up propagation news. The heatwave of midweek should be over by today, so any enhanced sea path Tropo will have weakened too. Coasts can be productive for ducts across the North Sea or the English Channel and Biscay in any quieter settled window during the week. Overall, Tropo is probably not a mode to rely upon this week, since much of the time we will have low pressure either over the UK or very close by. This will bring periods of rain or showers, many of which could have a chance of thunder and hail. This implies large convective clouds and potentially good GHz bands rain scatter. That leaves Sporadic-E, and we are still within the main part of the season, so keep up the usual procedure of checking mid-morning and late afternoon/early evening. Sporadic-E is a mode ideally suited for weak signals and digital modes can give good clues as to which directions may open later for CW and SSB as the opening develops. Make use of the good map-based clusters to see if you are close enough to where the paths cross. Ideally, the hot spot should be between about 600km and 1400km away from your station. Moon declination goes negative today but as perigee is on Monday, path losses will be at their lowest of the lunar month. 144MHz sky temperatures are low today but increasing to a peak of 2700K around midnight next Saturday. Compare this to the usual 300K cold sky temperature at 144MHz, do the maths and, you’ll see that your low noise preamps are not going to help you at this sky temperature! The June Bootids meteor shower peaked yesterday but continue looking for the best meteor scatter conditions around local dawn. And that’s all from the propagation team this week.

Hackaday Editors Mike Szczys and Elliot Williams discuss the highlights of the great hacks from the past week. On this episode we discuss wireless charging from scratch, Etch-A-Sketch selfies, the robot arm you really should build yourself, bicycle tires and steel nuts for anti-slip footwear, and bending the piezo-electric effect to act as a VLF antenna. Plus we delve into articles you can't miss about 5G and robot firefighting. https://hackaday.com/?p=355057

Sputnik and an uncle inspired George Allison, K1IG, to become a radio amateur. George had a long and successful US Navy career where radio was always the center of his activity including MARS stations, a visit to the South Pole, and the operation of very high powered VLF and ELF stations around the World. George promotes the Wordsworth method of raising CW speed above 40 words per minute.  K1IG is my QSO Today.

More natural radio;  Transduction and sonicism;  the  meditative stillness as a precursor to death.   With a side of Alvin Lucier and John Cage?  Delicious episode.  

More natural radio;  Transduction and sonicism;  the  meditative stillness as a precursor to death.   With a side of Alvin Lucier and John Cage?  Delicious episode.  

In this episode of the Dudes n Beer podcast host Christopher Jordan begins with a live call with David Koster, Alaskan resident to discuss the recent massive 7.0 earthquake that hit the state as well as the aftershocks and subsequent quake that have followed.

Various ways are used to predict a volcanic eruption that can help move people out of harms way in time: gas and heat output, earthquakes, ground deformation, electrical resistivity, VLF emission, and historical analysis, and even strange animal behavior, all come in to play.

This week has it all. Wondered about the VLF bubble around the earth? What about stories of those who died but weren't truly dead? We also have a light-hearted look at some Star Trek gadgets that exist now, way before the original story writers ever thought it possible! Have you heard of the term 'Attributional Bias'? It's not a commonly used phrase these days but the chances are, you exhibit this trait more times than you're aware of.. find out how to minimise it and be more aware of it - especially in small groups and collectives within the alternative community.Lastly, a check-in on healer development notes with dream experiences and dimensional travelling.. Our featured Musical artist, Indii Moon of Wildsilences, outro track "The Black Of Night' from the recently released album, "Beyond".
