Foundations of Amateur Radio I've owned a Yaesu FT-857d radio since becoming an amateur and at the time I was absolutely blown away by how much radio fits inside the box. It's smaller than most of the commercial radios I'd seen when I bought it. I came across a video by Michael KB9VBR, the other day showcasing a wooden cigar box with a complete, well, almost complete POTA, or Parks On The Air, activation kit. I say almost, since Dave KZ9V, the owner of the kit, points out that the box doesn't contain an antenna. It made me wonder how small is small? According to RigPix, the lightest transmitter on an amateur band, in this case, the 5 GHz or 5cm band, is an Amateur TV transmitter. Weighing in at 3.9 grams. The Eachine TX-06 is capable of FM with about 18 MHz of bandwidth with an audio sub-carrier. Of course, that's not a transceiver, but I thought it worth mentioning in case you needed an excuse for something tiny in your shack, besides, as far as I can tell, there's never too much Amateur TV in the world. I've built a crystal radio on a breadboard which is tiny, but it doesn't transmit, so to set the stage, I think we need to limit ourselves to transceivers, that is, a device capable of both transmitting and receiving, on amateur bands. Before continuing I'd like to express my thanks to Janne SM0OFV, for the rigpix.com database that he's been maintaining, in notepad, since 2000. Without the invaluable information documented for the currently 7,512 radios, I'd be spending an awful lot of time hunting for information. Moving on, the FaradayRF board is a transceiver, capable of using 900 MHz or the 33cm band. It comes in at 30 grams, but without a computer it's a circuit board with potential. The PicoAPRS by Taner DB1NTO, is a 2m transceiver specifically for APRS, weighs in at 52 grams and similar in look and a third of the weight of an Ericsson T18 mobile phone. Speaking of mobile phones, the PicoAPRS does WiFi and Bluetooth, can pair with your phone and act as an AX.25 modem. I'll confess, I'm drooling. Moving right along, for 70cm there's a Rubicson Walk 'n' talk, weighs in at 65 grams. Mind you, the RigPix database puts this under the "License-free / PMR446" section which comes with a sage warning, check your local laws before transmitting. There's a few Alinco DJ-C models for different markets that operate on 2m or 70cm, weighing in at 75 grams. The ADALM Pluto weighs 114 grams, but you'll need a USB power supply of some sort to make it do anything. It can operate between 70 MHz and 6 GHz, but the user interface is limited to a single button and LED, so if you want to interact with it, you'll need some external technology. Moving on to HF transceivers, weighing in at 199 grams, without the bag, but all the options, is the Elecraft KH1. Transmits on 40m, 30m, 20m, 17m and 15m and receives between 6 and 22 MHz. It's CW only, but you can receive SSB. If CW isn't your thing, RTTY and PSK can be used on the 40m band with a Silent System Handy PSK 40. Presumably the Handy PSK 20 runs on 20m. Both weigh in at 250 grams. The Zettl P-20xx SSB does SSB, AM, FM and CW, transmits on 10m, 11m, 12m and 15m as well as the MARS frequencies and receives between 14 and 30 MHz, weighs 300 grams. Even comes with CTCSS. Another Elecraft model, the KX2 weighs in at 370 grams, does 80m to 10m and the WARC bands, does SSB, CW and data. Mind you, you'll also need to add the weight for the microphone and paddles, and factor in a computer if you want to do more than PSK and RTTY. The Expert Electronics SunSDR2 QRP does 160m to 10m, the WARC bands and 6m. Weighs in at 500 grams, has a network port and two independent receivers. Operates at 5 Watts. There's no user interface, unless you count the reset and power buttons, so I'm not sure if it can operate on any mode with just a microphone, but given the "Depending on software" disclaimers throughout, I'm going to guess you'll need to bring a computer to make it sing. The Risen RS-918SSB does all HF amateur bands between 160m and 10m, has a user interface and display, even a big tuning knob, has built-in FreeDV and does FM, SSB and CW. I'd hazard a guess that this is the lightest self-contained transceiver that you can take out on a POTA mission to a park. Weighs 623 grams and comes with an internal battery. The Elecraft KX3 also does 160m to 10m, and 6m, with a 2m option. Weighs in at 680 grams, but that doesn't include any options. And finally, we pass 1 kilogram and hit 1,100 grams and discover a radio that does all bands and modes, the Icom IC-705 with a battery, but no antenna. The Yaesu FT-817, FT-817dn and FT-818 weigh 70 grams more, but that weight includes both a battery and antenna. Of course there are other options. For example, there's the (tr)uSDX by Manuel DL2MAN, and Guido PE1NNZ, does 80m, 60m, 40m, 30m and 20m, CW, SSB, AM and FM. Comes in a kit, weighs 140 grams. It's not on RigPix, so I only know about it because it was mentioned by Dave KZ9V. Similarly, I bumped into, wait for it, a single transistor transceiver called the Pititico, in case you're wondering, Pitico means very small in Portuguese and Pititico means very very small. Designed by Miguel PY2OHH, it comes in various revisions, including one by Ciprian YO6DXE, also known as DX Explorer on YouTube, complete with a circuit board design, and with some modifications can do AM in addition to CW. It's also not in the RigPix database and I have no idea what it weighs. The point being that this rundown is intended as a starting point to explore how small you can really get and still activate the Park or Peak you intend to. While you're contemplating weight, remember to account for power, control, and most importantly an antenna or six. Again, big thank you to Janne SM0OFV, for the rigpix.com website. Also, thank you for the memories of the Spectravideo SV-318 and SV-328, the last time I bumped into one of those was in 1980-mumble when I was working in a computer shop on the Haarlemmerstraat in Leiden, Mr. Micro Zap, if you're curios. What lightweight adventures are you looking for next? I'm Onno VK6FLAB

Wohoo, hey ya'll, Alex here,I'm back from the desert (pic at the end) and what a great feeling it is to be back in the studio to talk about everything that happened in AI! It's been a pretty full week (or two) in AI, with Coding agent space heating up, Grok entering the ring and taking over free tokens, Codex 10xing usage and Anthropic... well, we'll get to Anthropic. Today on the show we had Roger and Bhavesh from Nous Research cover the awesome Hermes 4 release and the new PokerBots benchmark, then we had a returning favorite, Kwindla Hultman Kramer, to talk about the GA of RealTime voice from OpenAI. Plus we got some massive funding news, some drama with model quality on Claude Code, and some very exciting news right here from CoreWeave aquiring OpenPipe!

GB2RS News Sunday, the 7th of September 2025 The news headlines: WRTC, QO-100 and how to have a thriving club – be part of these discussions at the RSGB Convention Listen out for special GB2RS broadcasts from the NRC as part of GB70RS celebrations The RSGB replies to the latest Ofcom 2.3GHz consultation The World Radiosport Team Championship 2026 takes place in the United Kingdom, and Mark Haynes, M0DXR, is the Chairman of the Organising Committee. Join Mark at the RSGB Convention on Saturday, the 11th of October, to find out how the team is progressing for the event, which will host 100 operators from all around the world. If operating via QO-100 is something you would like to try, join Paulo, F5VMJ/G0MUW, as he shares his experience of the mode, including his home setup and how to go portable. In a new-style presentation for this year, representatives from four amateur radio clubs will be joining a panel at the Convention. They will each discuss different aspects of their club activities that are contributing to the club's success and growth. Join the conversation, share your thoughts and experience, and be inspired. If you'd like to get practical during the Convention weekend, there are a variety of opportunities, including three workshops. The majority of workshop tickets are now sold, so book now to avoid disappointment. With only five weeks until the Society's annual Convention, secure your place via rsgb.org/convention. The RSGB Convention takes place at Kents Hill Conference Centre in Milton Keynes between the 10th and 12th of October. This year marks the 70th anniversary of the RSGB's weekly news broadcast, GB2RS. The celebrations continue with three special broadcasts scheduled from the RSGB National Radio Centre, or NRC, on Sunday, the 28th of September. Three Newsreaders will broadcast GB2RS from the NRC on the 40m band, the 2m band and via the QO-100 satellite. These readings will be in addition to those in the weekly GB2RS broadcast schedule. Special event station GB70RS will be used for pre- and post-News nets. In addition, each Newsreader will start the broadcast with a special message from the RSGB President Bob Beebe, GU4YOX. Find out timings and frequencies via rsgb.org/gb70rs  The RSGB has responded to a further Ofcom consultation, which would see new users sharing spectrum within the 2.3GHz amateur band. The latest proposals would enable a new class of short-notice outdoor deployments in the 2320 to 2340MHz range, for up to 14 days at a time. In its response, the RSGB has taken the opportunity to highlight strong concerns regarding the amateur weak signal segment at 2320MHz. This follows earlier Ofcom proposals last year for indoor use only in this frequency range. The response and background information can be found on the RSGB Spectrum Forum web pages. Go to rsgb.org/spectrum-forum  and choose the ‘Papers and consultations' tab on the right-hand side. This month is all about amateur radio and coding for the RSGB. Two exciting activities have been developed for you to get involved with. Whether you are a complete beginner or an experienced coder, you can get stuck into both the Python Pocket Morse activity and the LoRa high-altitude balloon challenge. Don't forget to let the Society know how you get on. Share your story and photos with the RSGB Communications Team via comms@rsgb.org.uk RSGB Board Chair Dr Stewart Bryant, G3YSX, has announced that Peter Bowyer, G4MJS, is stepping down from his role as RSGB Director due to an unexpected and significant increase in his professional duties.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 3rd of September Last week's aurora may have come as a bit of a surprise! The propagation segment for GB2RS is usually written on a Thursday, but the aurora was sparked by a solar flare that took place two days later, at 2002 UTC on the 30th of August. As we don't have a crystal ball, we couldn't have predicted it! The Kp index hit 3 late on the 1st of September, with aurora visible over much of the UK. HF propagation was affected with sudden swings in the maximum usable frequency over most of the day on Tuesday, the 2nd of September. At the time of writing, a geomagnetic storm watch remains in effect with the solar wind speed above 500 kilometres per second. September is a good month for aurora due to the Russell-McPherron effect, when the Earth's axis aligns perpendicularly to the Sun-Earth line during the equinox. This creates ideal conditions for a reconnection between the solar wind and Earth's magnetic field. So, keep an eye on solarham.com for daily updates. The Sun remains active with plenty of sunspots. The solar flux index stood at 187 on Wednesday, the 3rd, down from 202 the day before. HF propagation remains good, out of the auroral periods, and as we progress into September, it should improve even more. Some of the best DX this week included VK2/SP9FIH on Lord Howe Island using the Superfox FT8 mode, and T30TTT on Western Kiribati using both CW and FT8. Other choice DX included 3C3W in Equatorial Guinea on FT8, TJ1GD in Cameroon on 20m CW, and 5H8HZ in Tanzania on 30m FT8. Next week, NOAA predicts the solar flux index will decline to 160, and then perhaps 125. Unsettled geomagnetic conditions are forecast until the 10th, with a maximum Kp index of 4 predicted. This may be due to a large elongated coronal hole on the Sun's surface, which became Earth-facing on Wednesday, the 3rd. And now the VHF and up propagation news from G3YLA and G4BAO Rain and sequences of low pressure will drive the weather agenda for much of the coming week. The only reasonable chance of Tropo appears to be Friday and Saturday with high pressure to the southeast and support for paths to the continent and across the North Sea. It is worth noting that, in general, short-lived highs like this one do not have the necessary time to generate a strong, elevated inversion before declining. So don't expect too much. Rain scatter, on the other hand, is much more likely to be worth considering for the gigahertz stations next week, with plenty of rain events coming along. The Sporadic-E season daily blogs have now finished for this year, but you may still find it worthwhile looking at the Dourbes graph at propquest.co.uk. You will notice the odd blip on the foEs trace, so keep it in mind for the 10 and 6m bands – at least for the next week. Meteor scatter is still in random territory for this period. We are between the Perseids in mid-August and the Draconids, which peak on the 8th of October. This means that the pre-dawn morning hours will be good times to try. There were some auroral signals during the 2m UK Activity Contest on Tuesday, the 2nd. We are coming into the autumn season when conditions tend to be more favourable for aurora. The message is, of course, to monitor the Kp index for values rising above 4 or 5. Remember, these three-hourly planetary readings can smooth out shorter-duration peaks, so maybe don't wait for it to get to the dizzy heights of 6 or 7 before taking an interest. Moon declination is still negative, not going positive until Monday, the 8th. So, Moon window lengths and peak elevation will continue to increase. Path losses are still falling until perigee on Wednesday, the 10th. 144MHz sky noise is low all week. And that's all from the propagation team this week.

Tickets are selling fast, so to view the full programme and book, go to rsgb.org/convention  The RSGB has announced an exciting new volunteer role, which will be tasked with attracting older people to amateur radio. The Honorary Mature Members' Officer will also be responsible for retaining and engaging with our existing senior members. The individual will research organisations or groups with memberships that include older people who may be interested in amateur radio as a hobby. They will also help to identify ways the RSGB can support lifelong enjoyment of amateur radio, including accessibility, training and social engagement. If you are an RSGB member and interested in this role, go to rsgb.org/volunteers  to read the full description. If you'd like to apply or have a chat about the role, email the Nominations Committee Chair, Will Richardson, 2E0WYA via nominations.chair@rsgb.org.uk The RSGB will have a large presence at the National Hamfest at Newark Showground on Friday, the 5th and Saturday, the 6th of September. In addition to an extensive book stall and membership stand, the Society will be running a range of exciting practical activities and demonstrations. These include a semi-interactive display of the CubeSat and a web-based dashboard from a Tiny Ground Station running remotely. There will be the opportunity to play ‘MORSE', a minimalist, wave-based strategy game operated with just two controls. You can also have your CW skills tested at a range of speeds. On Saturday, there will be an opportunity to get hands-on, building a Kanga FM receiver kit. The activities are all free of charge, and there is no need to book in advance. Members of the RSGB Board, staff and representatives from specialist committees and teams will also be in attendance and are looking forward to meeting you, answering your questions and offering support. If you know an up-and-coming HF DXer who has made rapid progress in the last year and has some real achievements to show, you have until Friday, the 12th of September, to nominate them for the RSGB's G5RP Trophy. The award is not limited to youngsters or the newly licensed but is open to anyone who has recently discovered and made significant progress in HF DXing.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 28th of August 2025 This week saw a change in HF propagation with a perceptible move towards more autumnal conditions. The 10 and 12m bands have started opening up to the USA, at least on FT8. As we move into September, this will improve further. Also, as we head towards the Autumnal Equinox, we can expect better conditions on north-south paths, such as the UK to South Africa. The week saw the solar flux index climb to 226 on Thursday, the 28th, thanks to a host of sunspots, mainly in the Sun's southern hemisphere. Over the last seven days, the Sun also provided us with 12 M-class solar flares. Any associated coronal mass ejections, or CMEs, were not Earth-directed, so these had little effect, and the Kp index stayed firmly at 3 or below. The latest updates suggest that there is only a ten per cent chance of a strong X-class solar flare. FT8 continues to be the preferred HF mode, or so it seems, with stations in China, Japan, Indonesia and Cameroon making their way into UK logs on the 12m band. The 10m band has also been humming with South America rolling in during late afternoon and early evening. This can only get better as we move into September and October. NOAA predicts that the coming week will start with a solar flux index of 155 tomorrow, the 1st. This may be a little pessimistic, but we'll see. It also predicts that the solar flux index will drop off as the week progresses, ending the week at 125. Geomagnetic conditions are forecast to be good for the first half of the week, but then decline from the 4th of September. Batten down the hatches as a Kp index of 6 is forecast for the 5th, with unsettled conditions lasting until the 10th of September. Check for auroral HF signals on the 5th, or even the possibility of visible aurora from the UK. We recommend you get your HF DXing in early next week! And now the VHF and up propagation news from G3YLA and G4BAO Last week saw some lovely late-season Sporadic-E on the 6 and 4m bands, including Spain, Italy, and east into Ukraine. There was an opening to Brazil on the 24th that reached as far as East Anglia, but, as usual, stations on the south coast and west of the country had the best of the transatlantic QSOs.   This is the last bulletin in the nominal 2025 Sporadic-E season, which lasts from May to August. However, last week was a good reminder not to give up too soon, as there were several CW and SSB paths showing up, particularly on the 10 and 6m bands. There were also a few reports on the 4m band. The daily Sporadic-E blogs on propquest.co.uk  come to an end today, the 31st, but the site will continue to provide the maps as usual. To help you, notes on how to interpret the maps are available on the website. Thanks to all the Sporadic-E operators who have submitted logs to the various clusters this year. The change over to unsettled weather is now complete, and we will see rain and thunderstorms in most areas from time to time. It's a good period to check out rain scatter propagation if you are set up for the gigahertz bands. The heavier rain is well-captured by the many online rain radar displays to help you track the most active scattering volumes, which move with the stronger winds quite high up in the atmosphere. Speeds of 30 to 60 miles per hour are common. There is one note of contrast with the model evolution after midweek. One branch sticks with low pressure to the following weekend, while another outcome tries to bring in a ridge of high pressure and a chance of Tropo propagation. If the latter turns out to be the actual evolution, it may prove useful for the 144MHz Trophy and Backpackers Contest next weekend. However, it may not have arrived in time for the 144MHz UK Activity Contest on Tuesday. The solar conditions are still providing some interest for auroral propagation, but with a Kp index less than 3, nothing of use radio-wise. Look for a Kp index increase beyond 7 for that. Meteor activity is currently between major showers, so expect random activity, which suggests early mornings for checking out meteor scatter prospects. Moon declination is negative, reaching a minimum on Monda,y the 1st. So, it's a week to check out your equipment rather than to operate. With the Sun still high in the sky, it's easy to check system performance with Sun noise. Path losses started to fall after apogee on Friday the 29th. 144MHz sky noise is close to 3,000 Kelvin on Monday, dropping back to moderate on Wednesday. And that's all from the propagation team this week.

Hello and welcome to episode 75 of The DX Mentor, all about signal propagation. I'm Bill, AJ8B. Between the DX Mentor Facebook page, the weekly DX column in the Ohio Section Journal, the DX section of This Week in Amateur Radio podcast, and the This Week in DX weekly YouTube episodes, I have received quite a few emails over the past months about a couple of topics. One of those topics is HF propagation.I assume this is due to the discussions about the current solar cycle.If this is the first time you are joining us, Welcome! We have a back catalog covering many aspects of DX in both podcast and YouTube format. Please check us out. If you like what you find, please subscribe, like, and share to always be notified about upcoming events!    Another way to keep in touch and to see what we are up to is via the DX Mentor Facebook page. I will be posting aboutupcoming podcasts, YouTube drops,  as well as other DX events so please follow us.   You can check the show notes for any of the information that we discussed today. Before we get started, I would like to mention an accomplishment. Several weeks ago, I received the ARRL DX Trident award, 200 level. I was very honored to receive this and I thank the ARRL for continuing to find goals forus to strive for.In this episode we will have a detailed discussion of HFpropagation.  My guests are Bernie, W3UR, Frank, W3LPL and Joe, W8GEX. Bernie's call, W3UR, is probably familiar to you as he is theeditor of the How's DX column in QST and the publisher of the Daily DX and the Weekly DX.Frank's call is likely familiar to you as well as he publishes aweekly propagation report, is an avid DXer and has one of the most impressive antenna farms on the east coast. Check out his layout via qrz.com.Both Bernie and Frank are members of the 3000+ DXCC Challenge club, in the rare air of 3100+! This episode is definitely aided by the use of slides, but you can learn a lot as you listen to the guests discuss the various concepts. The YouTube version will drop in two weeks and you can round out what you missed the first time around.Now, let's tune in to our gurus and find out what they arediscussing…

Now the contest news Today, the 24th, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800UTC. Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator. On Tuesday the 26th, the RSGB SHF UK Activity Contest runs from 1830 to 2130UTC. Using all modes on 2.3 to 10GHz frequencies, the exchange is signal report, serial number and locator. The World Wide Digi DX Contest starts at 1200UTC on Saturday the 30th and ends at 1200UTC on Sunday the 31st of August. Using FT4 and FT8 on the 160 to 10m bands, where contests are permitted, the exchange is your four-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 21st of August Last week was relatively good from an HF propagation standpoint, with only a few periods with an elevated Kp index thanks to a high-speed solar wind stream from a coronal hole. The Kp index hit 4.67 on the 19th of August and 4 again on the 20th due to the solar wind hitting earth at more than 600 kilometres per second. Luckily, the interplanetary magnetic field remained mostly neutral, or north-facing, and the density was low, saving us from more disruption. Meanwhile, the solar flux index declined to 120 by Thursday the 21st. This is still high enough to affect the ionosphere, but well down on recent highs in the 140s and 150s. The daytime critical frequency has mostly remained above 7.5MHz, meaning the 40m band has managed to remain good for inter-UK contacts. This has also meant that maximum usable frequencies, or MUFs, over a 3,000km path hit 21MHz and even 24.9MHz at times. Nighttime critical frequencies have been around 5MHz, giving an MUF over 3,000km of below 14MHz and sometimes even as low as 10MHz. It may be another month or so before we see daytime F2-layer openings starting again on 28MHz. In the meantime, focus your efforts during daylight on 21MHz and below. T30TTT in Western Kiribati remains one of the DX stations to chase, mostly on 18 and 21MHz. The operators are alternating between using CW, SSB and FT8. Other choice DX worked included Jim, E51JD on South Cook Islands who has been active on the 17m band using SSB. TY5AD in Benin, Africa has been worked on the 10m band using FT8. And 3G1P, an IOTA DXpedition in Chile, was logged on the 15m band using SSB. Closer to home, today, the 24th, is the last chance to work OG0C on the Aland Islands. Next week, NOAA predicts that the solar flux index will remain in the 120s, until the end of the month when it could rise to 130 and even 150. Unsettled geomagnetic conditions are forecast for the 28th of August when the Kp index could hit 4. Otherwise, make the most of the relatively settled conditions over the first half of next week to work some choice DX! And now the VHF and up propagation news from G3YLA and G4BAO After this weekend, the weather changes from a Tropo high pressure pattern to an unsettled story with areas of low pressure and fronts together with wind and rain. This will remove any Tropo options and replace them with a possibility of rain scatter on the GHz bands. The auroral conditions have recently produced minor enhancements, although nothing too exciting so far radio-wise. It's worth noting that the autumn, along with spring, are times of the year when auroras are more likely. So, it's a good time of the year to keep abreast of the Kp index, especially if the Kp index goes above 5. We are at the tail end of the broader period of the Perseid meteor shower, ending today, the 24th. This leaves random meteor activity as the only option for a while. As those of you who are active in the mode already know, it tends to favour the early pre-dawn period for better chances of catching meteor scatter. Sporadic-E is hanging on for the last week or two of the 2025 season, but opportunities become much rarer. You'll need to keep a close watch on band reports to capture these increasingly fleeting events. In the main Sporadic-E season, there are usually two well-defined peaks of activity in the morning and late afternoon. However, in the tail of the Sporadic-E season you are just as likely to find it around the middle of the day as at any other time. The daily Sporadic-E blogs at propquest.co.uk  finish at the end of August, but in some years the last events have extended into the first week of September.  Moon declination is still positive, but falling, going negative on Monday. So, Moon window lengths and peak elevation will follow suit. Path losses are rising again as we approach apogee on Friday the 29th. 144MHz sky noise was low until lunchtime on Friday the 22nd, when the Sun and the Moon were very close in the sky. This continued throughout the Moon window on yesterday, the 23rd, and will revert to moderate-to-low next week.  And that's all from the propagation team this week.

Hey everyone, Alex here

Transcatheter devices are new to the heart failure (HF) community and treatment armamentarium for severe MR. This discussion focuses on the impact of transcatheter devices on HF patients and current barriers faced by referring specialists.

Get 10 free meals plus free shipping on your first box from HelloFresh with my code HF-0131 https://www.filify.co/SH8Cj In this episode, I'm getting real about the weird, messy, and sometimes lonely parts of your 20s that no one really prepares you for. I talk about what it's like to outgrow friendships, realize you need to be more selective with who you give your time to, and how social media makes it way too easy to feel like you're “behind” when you're actually right on track.I share my own experiences trying to balance having a social life with actually working on myself, and why learning to sit with discomfort has been crucial for my growth. We get into how to figure out your ideal vision for life, the small steps you can start taking to get there, and why it's normal to feel overwhelmed and unsure along the way.Nobody has it all figured out, we're all just adjusting as we go.

Hey yall! In this episode, I'm getting real about the pressures we face as women to hit certain milestones by a certain age, getting married, having kids, “settling down”, and how exhausting it is to feel like you're running against a clock. I talk about why life doesn't magically end at 25, why being single can actually be the most empowering time of your life, and why rushing into relationships or marriage just to “keep up” will never make you happy.I also get into the way social media fuels comparison, how people project their own insecurities onto you, and why it's so important to block out the noise so you can actually enjoy where you're at right now. We touch on the realities of parenthood (and why it's not something to take lightly), breaking free from outdated timelines, and fully embracing your individuality.Bottom line: stop letting society convince you you're behind, you're not!!

Foundations of Amateur Radio One of the many challenges associated with being a radio amateur is actually being able to listen to weak signals. If you're like me and more than half the planet, you live in an urban area, which comes with the benefits and pitfalls of having neighbours. From a radio perspective, there's plenty of noise that drowns out weak signals, so more and more amateurs are finding new and interesting ways to deal with this. Over the years I've talked plenty about so-called web-sdr, or internet accessible software defined radios. Essentially a radio receiver, preferably in a radio quiet area, hooked up to some software that allows you to listen in using a web browser. There's thousands of internet based services across the globe, the most popular of those are websdr.org and kiwisdr.com. As a new amateur you might have visited one or more of these and tuned around to listen to various radio stations and QSOs or contacts between amateurs, on bands that you can't access because you don't have the gear, or frequencies that are drowned out locally by your neighbour's pool pump, air conditioner, LED lighting, solar power inverter, television, motor home, cycle, or whatever else they seem to have an endless supply of behind closed doors. As a crusty amateur, and after about 15 years, I'm probably one of those, you might have started experimenting with building your own, or you might be blissfully unaware of these internet marvels. Either way, one restriction you run into is the ability to do anything other than listen. You might get the option to pick between Upper and Lower Side Band, or AM, sometimes even FM, but generally that's your lot. This means that trying to use such a tool to decode WSPR, or FT8, or RTTY, CW, PSK31, or whatever else takes your fancy becomes a challenge. It occurred to me that if you're able to capture the raw signal from a web browser, you could feed that into your decoder of choice. It would also mean that you wouldn't need any local hardware to start playing. Before you get all hot and bothered like I did. This is a non-trivial process that several others have attempted to wade through with varying levels of success. Much of the documentation I've discovered revolves around virtual audio cables and loop back software, and even the idea that you physically plug your computer's speaker output into your line input, or even hold a microphone up to your speakers. Aside from the lack of elegance associated with such contraptions, they require that you install all manner of weird software, and in many cases deal with permissions, since microphones are generally locked for good privacy reasons. Prompted by the webserial tool by Phil VK7JJ, it occurred to me that if we can talk to actual physical hardware within a web browser, then we can probably use a web browser as an audio source for local decoding software. Before you start hunting for the source code, there is none. I've spent the past few days playing around and although I made a waterfall display inside GNU Radio that used the audio from websdr.org, the results were not amazing, and I created a proof of concept by using a tool called BlackHole on the Macintosh I was using at the time. It's essentially doing shenanigans with audio mapping, not something which I really want to do, but it gives me a pretty picture, or not, as the case may be. More interesting is the progress being made over in the KiwiSDR community, where there is already an I/Q button, in other words, the raw data needed for processing further down the line. I came across projects that link the KiwiSDR to other tools, but it's unclear if that's the hardware, or the web client, I suspect it's the hardware, but I might be mistaken. If you're not sure what this might mean, think about listening to the same frequency at the same time across the globe using multiple web browser tabs, and comparing the signals in real time, or decoding them, or using them for comparing signal strengths, or propagation, or any number of things that are currently only possible with a vast network of radios under your own control. If you need to nerd out on the technicalities, the idea is that if you can access an SDR via a web browser, it would be cool if we could decode the stream coming back without needing to install software on the computer. There appear to be tools that do this kind of thing to get the audio into "ffmpeg". If that's gobbledegook to you, ffmpeg is a tool that allows you to do all kinds of cool stuff with audio and video. Using something called WASM, or webassembly, it's possible to link web browser audio to ffmpeg. I suspect it's possible to use the same mechanism to send audio to GNU Radio, or any other decoder, for processing. There also appears to be a thing called a Web Audio API AudioBuffer where the raw audio gets sent to, so perhaps that's accessible in some way. The point being, that I think this is doable, so much so, that I suspect that someone already did this. If you know of anything that fits the bill, let me know. In case you're wondering, this is tangentially linked to the Bald Yak project I've been working on, mainly because I need incoming RF into my shack and my HF antenna situation at present is really not up to the task, urbanite and all.

While expanding his education and eventually working at a number or companies as an HF engineer, Dan's first love was always spiritual exploration. In 2011, after a number of years of trial and error refining the process of self inquiry into deep self investigation, there came an undeniable recognition that he was not a separate self. Simply no one at all. There was only the selfless THIS, "aware existence". This became his permanent condition. Soon after, (from a certain perspective), Dan left a successful corporate position and his old life, following an intuited impulse to be in a more free, natural and creative circumstance. He now lives with his wife Victoria in the beautiful mountains of North Carolina, loving nature, exploring various forms of artistic expression and guiding others to awakening.

Hello and welcome to episode 73 of The DX Mentor - details about the upcoming VP2V DXPedition to the British Virgin Islands by our guests. I'm Bill, AJ8BHere is our guests story as presented by Bernie, W3UR: August 8-11: VP2V, British Virgin Islands - Brothers KK4LWR, Andy Milluzzi, and KD8RTT, Tony Milluzzi, are going on their first DXpedition August 9-11 in Tortola, British Virgin Islands, as VP2V/KK4lWR and VP2V/KD8RTT. Andy says that they are both big travelers and wanted to try a weekend on the air somewhere exotic, but also not get in over their heads. They decided to consider someplace they had been before, easy to get to and with “infrastructure.” Their gear will be a pair of transceivers, a DX Commander and another vertical on HF, a three-element Yagi for 6M, and wire antennas for other bands, 80-6M all told. They plan to focus on 30, 17, 12, and 6M SSB and try CW, with some digital [modes] “when we need a break.” They will capitalize on summer openings by being on 6M as much as possible. On August 11, they will take part in the HamSCI Meteor Scatter QSO Party on 10 and 6M. They will have a joint QSL card, and also upload to LoTW post-trip. QSL direct to KD8RTT.

Chad writes "Back in 1992, I was stationed at Ft. Lewis in the 3rd Battalion, 1st Special Forces Group (Airborne). We were running a force-on-force training operation. I don't recall the exact location—maybe an hour's drive from Lewis. Our task was to defend a simulated Surface-to-Air Missile (SAM) site consisting of a trailer and container meant to resemble a rocket launcher. We had two Special Forces Operational Detachment Alphas (ODAs) involved, roughly 20 guys total, plus a few support personnel. The site was backed up against the “no play zone,” so any attacking team could only approach from the west. It was fortified: two M-60 machine gun nests, a perimeter of seasoned operators, M-16s for each of us, a couple of HF radios—basic gear for a simulated “enemy” approach. No high-speed tech, no grenade simulators that I can recall. The terrain was layered: a track in front of the site, then woods, then a clean trail parallel to a ridge 150 meters to the west. Beyond that, a large field of tall grass. Ferns covered the ridge slope—dense and knee-to-hip high. Our mission was to intercept and resist any attempt to assault the SAM site, likely between dusk and sunrise. We ran rotating two-man patrols along the trail, each covering a three-hour shift. The night of the encounter, I was paired with a Sergeant First Class—an 18D medic whom I'll call “Guy.” He'd been in group for years. I was 22 at the time, on of the youngest on site. Moonlight was strong—brilliant enough to allow stealth movement. We paced slowly, stopping every few meters to kneel and scan. After an hour, we paused under a shadowed area. Guy lit a cigarette with quiet precision—no glow exposed. I asked how he did that. He smirked and said, “Sniper check.” Then it happened. A deafening scream rang out from the ridge. At first, I thought it was an animal. But then came a bizarre shift: halfway through, it took on a human tone. Eight to ten seconds of sustained vocalization that morphed into a frantic, incoherent babble… and finally, a coyote-like cackle or laughing sound. The volume never dropped. We scanned the ridge. I spotted a silhouette—a massive figure, turning swaying side to side near a tree at the top of the ridge. It looked human. I thought, “Who in group is that size?” We went guns up. The figure turned north and walked away. We pursued him, assuming a diversion tactic to draw us away from the site. But despite jogging, we couldn't close the gap. He moved quickly—strangely so. This went on for nearly a kilometer and a half. The forest thickened. The ridge narrowed – bottle necked. And then the figure veered east—straight toward us—charging downhill like a bipedal rhino through underbrush. Not sticks snapping… limbs breaking. I think at this moment, I realized It wasn't human and started to categorize it. We veered northwest off the trail to intercept. It turned north, the woods were dark – perfect place for a kill zone, an ambush, I could still track its movement. Then… silence. It stopped moving. Total quiet. We crept forward—as noted this was textbook ambush territory. But nothing came. The smell did. It hit in layers. First: wet dog tangled with decay. Then: putrid infection, feces, rot. It overwhelmed me. As the stench peaked, dread set in. Danger. Immediate and primal. I glanced at Guy. He nodded: time to back out. We backed out—me facing rear, unwilling to turn my back. I feared a charge. Surprisingly, Guy was only 15 feet behind. I suspect he walked backward too. Eventually we hit the trail again, dazed. We stood in silence. Not tactical—just stunned. I have no concept of how long we stood there. I remember being totally surprised by how far we went, and how far off the trail we went. Almost like an unexplainable time warp. We never spoke of it again. The only time I had heard what Guy had experienced was later that morning as he debriefed the CO and some of the others. There is much more to this encounter that I would like to discuss with you.”

Foundations of Amateur Radio Recently I was given some radio data captured on the 40m band. Using a piece of software called "Universal Radio Hacker", I attempted to decode it. At the time I thought that this might be Morse code, since then I've been told by someone who has been using Morse longer than I've been alive, that it isn't. I shared the data on my VK6FLAB GitHub repository where you can download it and see what you learn, and perhaps repeat what I did, or better still, improve on it. Over the years I've talked a little about how Software Defined Radio or SDR works, essentially it's a glorified Analogue to Digital converter, much like the sound card in your computer, which does the same, albeit at a much lower frequency. As it happens, you can represent the signal that comes into your radio antenna as a series of values. Essentially, the stronger the signal, the bigger the number, the weaker the signal, the lower the number. Let's talk about the characteristics of this signal. It consists of two parallel signals, in opposition to each other. The first signal jumps intermittently between 7 kHz and 40 kHz, where the second jumps between -7 kHz and -40 kHz. The recording is marked 7.06 MHz, so if we think of that as the central frequency, the whole signal sits between 7.02 and 7.1 MHz. This 80 kHz wide signal is not something you'd typically be able to hear using a standard amateur radio receiver which tops out at about 3 kHz bandwidth. It's so wide that you couldn't even hear more than one of the four tones at the same time. Randall VK6WR, who supplied the recording, spotted it on a waterfall display showing a chunk of radio spectrum, in fact, a $25 RTL-SDR dongle could receive this signal. Aside from the fact that this is a really wide signal, well at least in traditional amateur radio terms, it was interesting in that it was heard on the 40m band. As it happens, just after I shared my initial exploration, I was told by several other amateurs that they had heard the signal. I even saw it on a WebSDR in India and attempted to record it, but failed. As it happens, a few weeks ago, I was playing with something called "CAN Bus", or Controller Area Network, a technology that was designed in 1983 and is used all over cars for things like sensors for speed, engine temperature, oxygen level, detonation timing and anything else that's happening inside a car. You might know the end-user view of this called OBD2 or On Board Diagnostics, second generation. I was looking into it because my car has been acting up and I've been trying to track down the root cause. Anyway, I learned that CAN Bus is implemented using something neat, "differential signalling", where two wires each carry the same, but opposite signal, so they can be combined to ensure that in an electrically noisy environment like a car, the information still gets where it needs to go. Seeing the radio signal Randall shared, reminded me of this. Noise immunity is a useful attribute in digital HF communication, so I can understand why it was done like this, but it also means that either signal was sufficient to start to decode the information. We can use Universal Radio Hacker to show us only half the signal using a band pass filter. I then decided that the 40 kHz frequency was "on" and represented by a "one" and the 7 kHz frequency was "off", represented by a "zero". Of course that's entirely arbitrary, there's no reason that it cannot be the other way around, but for our purposes it doesn't matter at this time. That said, we don't yet have enough to decode the actual signal. We need to figure out how long each switch, or bit, lasts, because two zero's side-by-side or two ones side-by-side would look like a long "off" or a long "on". Using that logic, you could also say that the shortest possible duration for a 40 kHz or a 7 kHz tone would represent a single "one" or a single "zero". Of course, this is a simplified view of the world. For example, the data file contains more than thirteen and a half million bytes. Half of those are for the I in I/Q, the other for the Q. I'm purposefully glossing over a bunch of stuff here, specifically the notion of so-called I/Q signals, that's for another time. In computing a single byte can represent 256 different values. It means that if the signal is represented by a single byte, a voltage from the antenna at maximum amplitude can be represented as 255 and the minimum amplitude as 0. As it happens, voltages go up and down around zero, so, now we're only using half a byte, 127 for maximum, -128 for minimum. If we use two bytes, we get significantly more resolution, -32,768 as the minimum and 32,767 as the max. A little trial and error using another tool, "inspectrum", told me that the data was organised as two bytes per sample. Which brings the next point. How many samples per signal? Said differently, we're measuring the antenna voltage several times per second, let's say twice per second. If a tone of 7 kHz lasts a second, then we get two samples showing 7 kHz. If it lasts half a second, we only get one. As it happens, we're measuring over 22,000 times per second and using the cursor feature on Universal Radio Hacker, we can determine that each signal lasts 2,500 samples. It's roughly a rate of 100 bits per second. The "inspectrum" tool puts it at 91.81 Baud. It's not a standard Baud rate, sitting between 75 and 110 Baud. Using Universal Radio Hacker, I was able to decode 1,416 bits. You'll find them on my GitHub page next to the signal. Now for the fun. What does it mean? I started with looking for structure, by looking for zeroes. In short order I discovered several sequences of zero, then I noticed that there appeared to be a repeating pattern. After some trial and error, using the "grep" and "fold" commands on my Linux terminal, I discovered that the pattern repeats, more or less, every 255 bits. I say more or less, because there are a few bits that are not the same. I suspect that this is a decoding error which could potentially have been eliminated by using the noise immunity features associated with the differential signalling, but I don't yet know how to do that. Here's what I think I'm looking at. It appears to be a signal that's a unique identifier, specifically so that it can be used to synchronise two things together. In this case, I suspect that it's an over the horizon radar and the sequence is used to synchronise the transmitter and the receiver. I think that the signal strength variations are what allows reflections to be measured and I suspect that the actual transmitter and receiver are using more than two bytes to represent each sample, but I'm speculating. If you have an alternative explanation, I'm all ears. I'm Onno VK6FLAB

Bonus 10 - What happens when a former Army Ranger and Special Forces veteran finally reveals classified missions conducted during some of history's most volatile conflicts? Chris Brewer's military journey spans 24 remarkable years, from the reactivation of the 1st Ranger Battalion in 1974 to covert operations in Colombia during the Pablo Escobar era.In this gripping conversation, Chris takes us behind enemy lines into a world few civilians ever glimpse. Operating in civilian clothes with minimal support, his six-person team would check in just once weekly via HF radio to confirm they were still alive. While bombs exploded nightly in Bogota streets and gunfire erupted regularly, Chris and his team navigated this dangerous terrain while establishing a medical corpsman school as their cover mission. The real objective? A classified operation straight out of a Tom Clancy novel.Behind the tactical stories lies a deeply human journey. Chris opens up about raising his son as a single father while serving in Special Forces, depending on military friends to care for his child during deployments. His candid discussion of surviving rocket attacks and processing trauma offers rare insight into the psychological resilience required in elite military units. "You wake up and the first thing through your mind is I can't breathe," Chris explains, describing the aftermath of explosions that left him sleeping in rooms riddled with shrapnel.What makes Special Forces different from other military units? As Chris explains, "When there's only six of you, or 12 of you out there, all by yourself, a long way from home, you're probably not going to win very many gunfights." The key to survival isn't superior firepower but building relationships with local populations and understanding their needs—a philosophy that guided his entire career.Check out Chris's books "In the Shadows Between the Wars" and "Old Scroll Ranger" on Amazon to dive deeper into these declassified stories that shaped global security while remaining hidden from public view for decades. These firsthand accounts provide an unfiltered look at military service that will change how you understand modern warfare.Visit LandPirate.com to get your gear that has you, the adventurer, in mind.

I'm sharing my take on why it's not about whether he likes you — it's about whether you even like him. If you've ever found yourself questioning your worth in dating, this is your reminder to trust yourself, protect your peace, and stop settling for crumbs. Let's talk boundaries, safety, and becoming the version of you that refuses to shrink!

Following the resounding success of previous IOTA activations, such as Sacrifice Rock, Kanika Island, Sagar Island, and Nachugunta IOTA, the foundation is gearing up for more exciting adventures. DX India Foundation's primary objective is to activate rare IOTAs, organize DXpeditions, and foster a vibrant DXing culture in the region. To achieve this goal, thefoundation is seeking support from manufacturers, individuals, and organizations to acquire essential equipment, including: – HF radios and amplifiers. – Band-pass filters and power supplies. – Tents and generators. – Coax cables and all necessary accessories. The foundation plans to establish a self-sufficient setup, comprising three stations, which can be easily transported in a container to various locations. This will enable DX India Foundation to activate rare IOTAs and provide DXers and IOTA chasers with exciting opportunities to log new entities. By promoting DXing activities and providing support to IOTA enthusiasts, DX India Foundation hopes to elevate the region's profile in the global amateur radio community. Join us in celebrating World DX Day and stay tuned for updates on DX India Foundation's initiatives and activities! for more details: sara@vu2rs.com 73, Sarath,VU2RS - DX India Foundation” Here is some information about our guest:Sarath was born and raised in Hyderabad, India.

Use code HF-0131 and my link https://www.filify.co/SH8CjIn this episode, I'm getting real about that awkward, lonely in-between phase of healing and growth — especially in your mid-to-late 20s when you're outgrowing old habits, friendships, even whole versions of yourself. I talk about what it's actually like to let go of things that don't serve you anymore (even when it sucks), and how choosing *you* can sometimes feel isolating AF. I share some personal stories, reflect on the power of solitude, and why quality is over quantity when it comes to connections. If you're in that weird limbo between who you were and who you're becoming, this one's for you. Your journey is valid — and you really *can* build the life you want.enjoy & dont forget to tweet/ig story me a screenshot of you listening!MY NEW WEBSITE!!
