Foundations of Amateur Radio Recently I came across a series of strident posts about the injustice associated with a non-amateur service using the 70cm band. Complete with links to discussions, spectrum plots, angst and even incoherent outrage, all related to the notion that whomever "allowed" this user to transmit on this band was clearly incompetent. Except, that this is probably not the case, or the full story. So, what's going on and why are people incensed? This all started at least six years ago. Since then AST SpaceMobile has deployed seven low Earth orbit satellites and used the 70cm band to communicate with them. Although in the trial phase, there's plans for an additional 243 satellites, and there's at least one other company playing in the same space, Atmos Space Cargo. The outcry from amateurs is around the commercial use of "their" 70cm amateur band. It's an emotional statement, but what is the reality? Before I dig in, let's set some terms. Radio frequencies are globally coordinated because electromagnetism doesn't care about sovereign borders. This coordination is conducted at the United Nations by a body called the ITU, the International Telecommunications Union. Within that body, amateur radio gets a seat at the table from an organisation called the IARU, the International Amateur Radio Union. For the purposes of the ITU, the world is divided into three, Region 1, or essentially Europe, Russia and Africa, Region 2, the Americas and Greenland, and Region 3, the rest of the world. There's more to it, for example, Antarctica is split across all three, but for the moment, that really doesn't matter. Of interest is that the band plan, the agreements that outline which frequencies are set aside for what service, might be defined differently across each of those three regions. To add complexity, each country can be granted exceptions. I don't know the exact mechanics of how this is achieved, but I can guarantee that there's lots of haggling and foot stomping, diplomatically of course. If you're curious how I come to that observation, just look at the absurd list of exceptions associated with each band plan allocation. Further complexity is added by the fact that not all allocations occupy the same frequency range. For example, in Region 1, the 2m band for Amateurs exists between 144 and 146 MHz, in Region 2 and 3 it's between 144 and 148 MHz. Within an allocation there is the concept of shared and exclusive priorities. These determine who "wins" if two stations with a different service are transmitting on the same frequency. Essentially, a secondary user may not interfere with a primary user and a tertiary user may not interfere with either a secondary or a primary user and so on. A primary user can pretty much do what they want, as long as they stay within the allocation and don't interfere with other primary users. As a result, the order in which services are listed, matters. An exclusive allocation doesn't have to be shared at all. Between regions these service priorities might not be the same. For example, in Region 1 between 430 and 432 MHz is allocated to Amateurs and Radio Location, but in Region 2 and 3 it's between Radio Location and Amateurs. So an amateur using that frequency whilst in Region 1 would be a primary user, but in Region 2 or 3 they wouldn't. As an added wrinkle, for example in Australia, that slice is "primarily for the purposes of defence and national security", even though Radio Location is the primary service and Amateurs the secondary one. As a bonus, amateurs in Australia have access to 420.8 to 421.2 MHz as a secondary service, even though the ITU designates this as Fixed, then Mobile, except Aeronautical Mobile, and then Radio Location. Although amateurs are a secondary service, they come after the Department of Defence who are the primary users for those frequencies in Australia. Between 420 and 430 MHz, and from 440 to 450 MHz in several countries, Australia included, the Amateur Service is explicitly designated as a secondary service even though the band plan doesn't actually show this. If you're confused, you're in good company, since this tapestry of regulation isn't as straightforward as the "70cm band is an amateur band", in fact, I'd go so far as to say that it's not an amateur band at all, except perhaps in Region 1 between 430 and 440 MHz where Amateur is designated as the non-exclusive primary service. Back to the blow up. AST was at one time authorised to use 430 to 440 MHz for trial purposes by a regulator in Region 2, the FCC, the United States Federal Communications Commission. I suspect that at the time, the Blue Walker 1 nano satellite was experimental and the approval made sense. You can argue that whomever initially allowed this made a mistake, but, reality is whatever the regulator says it is, unless someone at the ITU objects. It appears that the FCC has since been attempting to make AST comply, instead with billions of dollars at stake, AST continues to apply for more spectrum, which they apparently originally filed with the ITU through the Papua New Guinea administration. It's unclear if the FCC has since capitulated. There is evidence that the new commercial AST satellites are transmitting outside of their authorisation, euphemistically described as "IARU Uncoordinated". Ask yourself, how is it possible, or even allowable, that a regulator permits use of radio spectrum outside its borders and what penalties and remedies exist? The ground stations using these disputed frequencies are all outside the USA. One of the five ground stations is in my own city, Perth in Western Australia. I haven't noticed any discussion on this topic within my local community, even though this has been brewing for years. It does raise a bigger question. How is the band plan enforced? I mean, the 40m band is pretty much unusable in VK6 between sunset and midnight thanks to the fishing fleet of our northern neighbours, it's been like that for as long as I've been an amateur and I expect no change during my lifetime. How is this satellite fleet operating on the 70cm band any different? That said, I cannot help but wonder, will the originally authorised 50 kHz signal every eight seconds, not for phone calls to space, and only for 24 hours after launch or in the unlikely event of an emergency, for Telemetry, Tracking and Command, actually cause issues, or will it be an opportunity for radio amateurs to learn how to deal with interference? Speaking of interference and considering the allocated services, who is interfering with whom here and what priorities and remedies exist? Recently I talked about promotion, and the lack thereof, across our community. This is an example of promotion, and despite the uproar this week, a very poor example at that. Searching for "AST SpaceMobile", the oldest post I could find was on the German AMSAT, or Amateur Satellite forums back in September 2022 by Peter DB2OS who has been very active on this matter. His original post was in English, but went on to discuss the issue in German. I only found it after specifically looking for the names of the organisation involved. Peter's posts supplied links to many of the documents I consulted. Despite having links to specific pages, I found no search results for "AST SpaceMobile" on the websites for the regulators in the US, UK, Germany or Australia, and none on the ARRL, RSGB or DARC. The WIA produced two glowing news reports around the beginning of 2023 about this wonderful new mobile phone service. No mention of the 70cm band. The only active discussions appear to be the German and UK AMSAT forums, that and all the glowing investor posts. In other words. This is the equivalent of publishing the information at your local planning department in Alpha Centauri, 50 years before the event and hoping for a good outcome. As a potential path forward, in January 2023 the German regulator forced AST to shut off 70cm operations whilst it was within radio visibility of Germany. I don't know if that's still in effect, or how and if it's being enforced. It appears that AST has been lobbying for the use of this spectrum for a long time, not just the 340 page submission made last month. For example, NASA made its first response to this satellite constellation in October 2020. It appears that the WIA responded four years later, but I have yet to see it, and this week the Bulgarian Federation of Radio Amateurs, the ARRL, and RSGB added theirs. The IARU issued a statement this week too. The fact that we're still arguing about it over half a decade later is a good indication that how we're responding as a global community is clearly ineffectual. Perhaps that is what we should be arguing stridently about. So, where do you stand on this? Should something be done about this, and if-so, what, and more importantly, how? I'm Onno VK6FLAB

Foundations of Amateur Radio Around the world are thousands of associations, groups of people, clubs if you like, that represent radio amateurs. Some of those associations are anointed with a special status, that of "member society" or "peak body", which allows them to represent their country with their own governments and on the international stage to the ITU, the International Telecommunications Union, through a global organisation, the IARU, the International Amateur Radio Union. Some of these are known across our whole community, the ARRL in the USA, the RSGB in the UK, and the WIA in Australia. Some much less so, the CRAC, the Chinese Radio Amateurs Club, or the ARSI, the Amateur Radio Society of India, for example. In an attempt to get a deeper understanding of what distinguishes these organisations, I visited a dozen member society websites. Cultural sensibilities and aesthetics aside, the variety and sense of priority is both pleasing and astounding. Starting close to home, the WIA, the Wireless Institute of Australia, shows news as the most important and the top story is a radio contact between the International Space Station and a school, held about two weeks ago. The ERAU, the Estonian Radio Amateurs Association, features an article about the 2025 General Meeting outlining who was there, what was discussed and thanking the participants for their contributions. When I visited, the ARRL, the American Radio Relay League, top news item, was the renewed defence of the 902-928 MHz Amateur Radio Band, from a few days ago. The most important issue for the ARRL is that you read the latest edition of QST magazine, but only if you're a member. The RSGB, the Radio Society of Great Britain, has an odd landing page that links to the main site, which features much of the same content. The latest news is "Mental Health Awareness Week" and encourages us to celebrate kindness in our community. The DARC, the German Amateur Radio Club, has a page full of announcements and the top one was an article about current solar activity including a coronal hole and various solar flares. The ERASD, the Egyptian Radio Amateurs Society for Development, uses qsl.net as its main website. It features many images with text, presumably in Arabic, that unfortunately I was not able to translate. Curiously the landing page features some English text that welcomes all interested to join. I confess that I love the juxtaposition between a Yaesu FT-2000 transceiver and the images of Tutankhamun and the pyramids. The RAC, the Radio Amateurs of Canada, use their homepage to promote its purpose, and features many pictures of their bi-monthly magazine, which you can only read if you're a member, which is where many of the homepage links seem to go. The RCA, the Radio Club of Argentina, is promoting the 2024-2025 Railway Marathon, including links to descriptions of what constitutes a Railway Activation, how to reserve your station, and upcoming and past activations. There's also a reminder to renew your license. The ARSI, the Amateur Radio Society of India, has a very sparse landing page showing their mission and not much else. Clicking around gives you lots of information about the history, activities, awards and the like. Unfortunately, I wasn't able to find out how to become licensed in India. There's hardly any images. In contrast, the URA, the Union of Radio Amateurs of Andorra, lands you on a page with contact details and not much else. Clicking through the site gives you lots of pictures of happy people and maps, lots of maps. The KARL, the Korean Amateur Radio League, features an announcement with a link to the 24th Amateur Radio Direction Finding, from a week ago, but it requires a login to actually read it. The JARL, the Japan Amateur Radio League, features an announcement to a form you can complete to join the "List of stations from which you do not wish to receive QSL cards." The NZART, the New Zealand Association of Radio Transmitters, features a big button to latest news and clicking on it shows the "Jock White Field Day", which was held several months ago. I wasn't able to see the CRAC, the Chinese Radio Amateurs Club, since the page didn't load for me. The "Wayback machine", also known as archive.org, from a capture a few days ago, showed a news item announcing the intent to organise the 1st Class C Amateur Radio Technical "something", I say "something" because I cannot actually load the article and see what it has to say. The event was scheduled for a month ago, the announcement was from several months ago. Content aside, finding sites was interesting too, mind you, there's plenty of member associations that don't have any web presence at all. Is that by choice, or necessity? The IARU list of member societies conflicts with the list of national organisations shown on Wikipedia. The IARU has about 160 entries, I say about, since the list isn't really formatted as much as it's congealed. Let's just say, perhaps a table for tabular data might be a novel approach. Wikipedia is slightly better formatted, it lists 93 national organisations. As it happens, both include a link to the national organisation for China, which is either the Chinese Radio Sports Association, with apparently two different acronyms, either CRSAOA, or CRSA, or if you believe the IARU as a source, it's the one I mentioned earlier, the CRAC. I don't know which one is right, but at least we can assume that the IARU page was updated formally, rather than edited by someone on the internet. Regardless of which one is the "real" Chinese national amateur radio organisation, none of the websites loaded for me. Let's move on. It's interesting that several non-English sites like Korea, Japan and Germany feature a button that allows their site to be translated into English. What's even more interesting is that the English version of the site is not in any way the same content. In many cases it appears to be information relevant to English visitors rather than a translation. One notable exception is Estonia, which allows a visitor to read their site in Estonian or English right out of the box. Unsurprisingly, the ARRL website has no buttons for Spanish, even though that represents about 13 percent of the USA population, let alone any other language. I'd encourage you to visit a few and see what you can learn about the other members of our community around the world. My visits leave me with questions. What do these organisations stand for? What do they do? Are they there for amateurs, for aspirant members, the general public, for regulators, for their members, for fund raising and advertising, or international visitors and tourism? It seems to me that looking at just a few of these organisations reveals a great many things about how they understand their own role and how they deliver service and just how much money they have to play with to make that happen. I'll leave you to ponder how effective they might be and what your role is in that endeavour. I'm Onno VK6FLAB

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 1st of May 2025 After the previous week's geomagnetic disturbances, as described in last week's GB2RS, the last seven days have been relatively quiet. The Kp index has mostly been in the ones and twos, however the rise to a Kp value of four on Thursday the 1st of May could herald a return to unsettled conditions. The solar flux index peaked at 170 on the 24th of April, before declining to 148 at the end of the month. HF conditions have been acceptable rather than outstanding and many stations struggled to work DX at times during International Marconi Day on the 26th of April. Nevertheless, there is DX about including ZS8W Marion Island, TX9A Austral Islands and HD8G Galapagos Islands. A look at the Proppy propagation prediction tool will help you work out the best times for making a contact with each station and on each band. You can find it by going to rsgb.org/propagation-tools Looking ahead, a large sunspot has rotated into view. Now designated 4079, this region has returned and was previously sunspot region 4055. It has already emitted an M-class solar flare, and we may expect greater activity as it becomes more Earth-centric over the next week. NOAA predicts that the solar flux index will climb again in the coming week, perhaps rising to between 160 and 165. Geomagnetic disturbances are also due to rise, with the Kp index forecast to reach five on the 5th and 6th of May. If this becomes a reality, expect lowered MUFs and poorer HF paths, especially over the poles as the Kp index rises. And finally, this week traditionally marks the start of the Sporadic-E season so keep an eye on 10m and 12m for short- and medium-range openings to Europe. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of high-pressure Tropo weather weakened a little as last week ended and we'll see the return of unsettled conditions with showery rain, perhaps even the odd thunderstorm. This is unlikely to lead to a total removal of high pressure and Tropo will still be worth looking for, especially over the western side of the UK. Some models place a new high just west of Britain during the coming week. This means that the rain prospects are not great, although probably just enough for a hint of rain scatter in any isolated heavier showers. The HF bands sounded a bit ‘watery' at times last week, which is a classic sign of potential aurora to explore on the higher bands. Look out for aurora in the coming week if the Kp index climbs above five. Meteor scatter is worth thinking about and, after last week's Lyrids, we now have the Eta Aquariids shower peaking in the early hours of the 6th of May. Remember that Sporadic-E ionisation is largely composed of long-lived meteor ions, so be on watch for Es openings. From now onwards through to mid-September, Sporadic-E will dominate the lower VHF bands, so check the clusters for signs of activity. Remember that Es starts on 10m and moves HF as an opening develops, even reaching 2m in the peak summer. Unlike Tropo, Es events are often fleeting, so the best you can do is monitor conditions as the Es intensifies and be ready when it reaches the band you want. Don't forget to check the daily Es blogs on www.propquest.co.uk which discuss the potential links between location of jet streams and Es formation. EME path losses are increasing, but apogee is still a week away. Moon declination passed maximum last Thursday so Moon windows are shortening along with reducing peak elevation. 144MHz sky noise is low all week. And that's all from the propagation team this week.

Por mais clichê que pareça, o ensinamento que cada um tem a própria trajetória é muito verdadeiro, não existe regra para o jogo da vida e a estudante Darc Andréa de Souza Silva é exemplo disso. Aos 61 anos de idade ela começou a estudar Jornalismo na faculdade Estácio, em Belo Horizonte, e hoje aos 65, no oitavo período, faz estágio na Rádio Itatiaia.Mas para conseguir realizar esse sonho, ela precisou guardá-lo por um tempo. Quando tinha apenas 14 anos, Darc perdeu a mãe e teve que assumir a enorme responsabilidade de cuidar dos irmãos mais novos. Além disso, depois de mais velhos, Darc também cuidou do pai e do avô.Atualmente, ela trabalha como taxista, profissão que exerce há 45 anos e entre passageiros e quilômetros rodados, ela construiu não só um caminho profissional, mas uma história de força, superação e amor pela comunicação.

The Duffy antigen, also known as the Duffy antigen receptor for chemokines (DARC), plays a critical role in immune system regulation and disease processes. It is a protein found on the surface of red blood cells and endothelial cells, known primarily for its function as a receptor for chemokines and its role in malaria resistance. However, emerging research has highlighted a fascinating link between the Duffy antigen and systemic lupus erythematosus (SLE), an autoimmune condition. In individuals with lupus, the immune system becomes overactive, targeting the body's own tissues and causing widespread inflammation. The Duffy antigen has been implicated in this process because of its role in modulating immune responses. Specifically, DARC binds to and regulates the levels of chemokines, proteins that guide immune cells to sites of inflammation. Dysregulation of this pathway may contribute to the heightened immune activity observed in lupus. Additionally, certain genetic variations in the Duffy antigen, such as the Fy(a-b-) phenotype, which is common in individuals of African descent, have been associated with altered susceptibility to autoimmune diseases, including lupus. These variations may influence the way the immune system interacts with chemokines and other inflammatory signals. Understanding the relationship between the Duffy antigen and lupus opens new doors for research, offering insights into the genetic and molecular underpinnings of the disease. This connection also holds promise for developing targeted therapies aimed at modulating immune responses in lupus patients, potentially improving outcomes and quality of life. By exploring the link between the Duffy antigen and lupus, scientists are unraveling the complex interplay between genetics, immune regulation, and autoimmunity, providing hope for better treatments and a deeper understanding of this challenging condition.

In episode 314 UNP founder and curator Grant Scott is in his shed reflecting on the need for change, and explains how the podcast will be evolving now it is coming from a garage and not a shed! He aslo reads a short extract from his latest book Inside Vogue House: One Building. Seven magazines. Sixty years of stories... Plus this week, photographer Holly Revell takes on the challenge of supplying Grant with an audio file no longer than 5 minutes in length for the last ever answer to the question ‘What Does Photography Mean to You?' Holly Revell describes herself as an artist photographer who makes collaborative portraits with fellow queer folk exploring transforming identities. They have been working on their current project ‘People Like Us' since 2017, recording trans, gender non-conforming and non-binary identities and experience, which will be published as a book this year. Other projects include 'DARKROOM'; a series of photo-booth installations at art & club events (2010-14), ‘Transformations', photographs made with performers reflecting the transition from drag to self in one long-exposure (2016), a book titled ‘David Hoyle: Parallel Universe' (2017) and DARC which stands for documentation action research collective 2016-19). Holly has made a significant contribution to the documentation of queer performance and its icons in London, creating a record of a specific movement and the community surrounding it, which is archived at the Bishopsgate Institute. www.hollyrevell.co.uk Dr.Grant Scott After fifteen years art directing photography books and magazines such as Elle and Tatler, Scott began to work as a photographer for a number of advertising and editorial clients in 2000.

The history of training can be depicted like a spiral. While back and forth it looks like a flat circle with what was popular 30 years ago once again in vogue. Pull back a little, however, and that circle is going somewhere. Tim Selbrede returns to the REDACTED Culture Cast to talk about lessons learned from Night Vision instructor courses and DARC to go beyond the memes about how CQB is a good way to die. Beyond developing skills, as we have had opportunities to consider and analyze not only what we train, but how we do it, we better equip future generations to excel where we struggle.

Show Notes:  https://wetflyswing.com/512 Presented By: Angler's Coffee, Smitty's Fly Box, Waters West, Jackson Hole Fly Company Today we go fly fishing for carp with none other than Bill Marts. We explore Bill's invaluable tips on targeting carp in Banks Lake and discover the story behind the Schmoots Clooper Invitational. Plus, don't miss the stories behind Bill's iconic fly patterns and the tattoos that commemorate them. Grab your earphones because this one is packed with carp wisdom and captivating stories. Fly Fishing for Carp Show Notes with Bill Marts 03:00 - Bill's fishing roots trace back to his younger years in Oklahoma, armed with nothing more than a cane pole, bobber, worms, and a minnow. Despite the absence of any fly fishing enthusiasts in his family, Bill's interest was piqued through books and television shows. 06:43 - Bill tells us how he started his own fly shop, Blue Dun, in Wenatchee. He worked at REI for a long time and always dreamed of having his own fly shop. 08:30 - Bill and his brother have put together an award-winning movie in 1976 called Angler's Autumn. 10:00 - In 2005, he decided to give up his fly shop as he was offered a position in the travel department at The Fly Shop. Schmoots Clooper 17:30 - Bill got into carp fly fishing during the early '90s after a float trip down the Winchester Wasteway with his wife. It was during this time that his friend, Darc Knobel, who once worked with him in Wenatchee, also became intrigued by the idea. Darc now runs his own fly shop, Desert Fly Angler, in Ephrata, Washington. Together, they eventually unlocked the secret to successfully catching carp. 21:00 - In the late '90s, they kicked off the Schmoots Clooper invitational. The name was inspired by a paragraph in John Gierach's book. 30:00 - Bill gives valuable tips for successfully targeting carp in Banks Lake and similar waters. 34:00 - Bill's go-to fly for carp fly fishing is the Bugeye Carp Wooly, a pattern he's so fond of that he even had it tattooed on his thumb. 49:49 - We discussed the difference between using a cane pole compared to a two-handed spey rod and a single-handed rod for carp fishing. 1:03:00 - Bill tells us about the first steelhead he caught on the fly. 1:06:00 - Bill's favorite steelhead fly, known as Bill's Bead Butt Burlap, is also tattooed on his arm.
