The Radio Society of Great Britain (RSGB) is the UK’s national society for amateur radio enthusiasts. It is dedicated to the development of the science and practice of amateur radio. The Society works to increase awareness and understanding of amateur radio and to make the hobby accessible to everyone.
The RSGB represents the interests of the UK’s 60,000 licensed radio amateurs to the UK government through Ofcom, the UK radio spectrum regulator, and to the international organisations that govern the hobby. It also conducts the examinations that are required for enthusiasts to become licensed as radio amateurs.
We hope that the videos on our RU-vid channel explain more about amateur radio and celebrate the diversity of this great hobby.
This is first time that I got a lot of full explanation of maximum improvements for a magnetic loop antenna. Thank a lot, and, please, continue to do search and sharing with HAMers.
Interesting edition. Thank you. G4TFF. From a blind amateur’s point of view, some comments that might be helpful. Kenwood 590SG is probably still the most accessible HF base station around, both for its voice output and use of buttons and knobs to control. RAIBC produce RADCOM every month as a digital audio version, called Reading Rattle. CQ Blind Hams is a useful video channel . and for a request to manufacturers esp regarding Touch screens; need to go further than just screen reading. I need to be able to touch to hear/read the screen then tap to select or execute the operation. Eg Synnaptic software as used on mobile phones and tablets.
Nice info on Y stations. I have had to look into them from kryptos sculpture. Station X, Alexander Y station, typex, camp X, Hydra radio. Agent X, X Corp, ect.. Ghost stations, Ghost whisperers, Ghost army. A rich history. Thank you for sharing the video.
We often come across imteresting schematics in books and magazines, is there any way to "Copy and Paste" directly inmto the software? As a beginer to building from a circuit, I can see the real possibility of errors creeping in due to a lack of experience, or simple "overload" for a novice! 73 Jim M7BXT
Thanks for your question. It is because so many electronic components are based on imperial pitches even now in 2024. The lead pitches on leaded integrated circuits as well as many connectors etc have always been based on pitches of multiples of 0.1" and this continues with new devices to maintain compatability, so whilst dimensions like PC board sizes may be in metric you will often find that component lead pictures are imperial.
@@iandobson8846 Both - for example an 0603 size component which is .06 x .03 inches is also known as 1608 which represents the size in mm. It's just historical and in practice is not really difficult to work with.
If you chance the rolling inductor at my station while transmitting through the ATU. This would be the last thing you did. Allthough this video is 3 years old, I still think I should mention this. You NEVER chance a rolling coil while transmitting. The coil might produce high voltage. Instead, start with the rolling inductor and listen to the noise and tune for maximum noise. Then when you find the sweet spot, tune the capacitors while transmitting. And tune for minumum SWR. Chancing a rolling inductor while transmitting is not done and I consider this very bad advise....... (PA5MC) static.dxengineering.com/global/images/instructions/mfj-962d.pdf Page 7 of the instruction manual "WARNING: Never change the antenna or Inductor selector switch position while transmitting ! Never apply more than 800 Watts to the MFJ-962D !"

Way back in the 80's I sat my radio ham exam & passed with flying colours. But I never bothered with a licence with young family etc. My friend sat his at the same time & also passed. He got his licence & used his equipment. I recently got reinterested in the hobby & bought a 991A & various aerials etc. I applied for a licence & was granted a foundation licence. Never taking the morse code. My friend never did either. He has a full i think G6 licence & I do not, I have a M7. We both hit the same criteria. This has disgruntled me to a point that with 10W on SSB & my friend 100W. I have pretty much given up & will soon be putting all my equipment up for sale. I argued with the ofcom guys to give me a full licence & was flatly refused. Way back in the early 80's I used to spend a lot of time repairing CB radios & doing upgrades. I used to make my own notch filters & run 3-400 watts from my home with no interference to neighbours. Talking pretty much all around the world , with postcards I even joined the world wide radio club Which was WW106. Why should I have to take more exams to go from foundation when my friend has a full licence. Well why am I posting this. Pretty much because you want more members & make it so hard to be part of it. I would taske more exams but at 72 years old think I have sat more exams than soft mick. If you read this then thank you for taking the time. Steve. M7 DOZ. Out.
Also, when somebody commits to taking the tests, how about a wingman being assigned to them, to back them and if they pass put theory into practice, but also help them if they don't succeed first time in an exam .
I might be preaching to the "converted", but would it be a good idea to co-opt some teenagers as ambassadors, and also some people in their "twenties" and "thirties" as they are the live feedback of where the future of the (this marvellous) hobby is coming from.
Well done to all the RSGB team. It is a shame that the live chat appears not to have been archived for the sake of those of us who could not watch live.

DF9IC/DR9A here: 13:45 we "cross the streams" intentionally - but this works only under special conditions and with full phase control between the various groups. You are 100% correct for the usual setups. 23:58 we used a single 14 MHz crystal filter for our run frequency since 2006, and also built one for our next neighbour soon after. BTW they used to produce up to -13 dBm at our antenna before they changed their QTH a bit. The filters on both sides help to stay happier 😀 - Since about 2016 each OP has his own box with switchable 14 MHz filters from S53WW. 27:27 cannot agree enough. We have a PERSEUS SDR with home made downconverter which allows to measure down to -150 dBc/Hz on site connected to PA monitor outputs because sometimes shit happens, and we want to know. - Reliability is the key if you have tuned your station otherwise - in 2022 we lost to SN7L by 0.8% because we had a 45 min 230 V power outage on Sunday morning. 32:27 during peak hours we have a 3rd OP in the background to arrange skeds on KST for the two active OPs. I like your presentation very much, it reflects our own thoughts.
Okay, I get the relevance of the head echo’s Doppler being used to determine velocity and by triangulation path, but could not the tail echo be used to extrapolate tail length and also path? Found this to be an extremely informative and professionally delivered presentation about an aspect of amateur radio I had never previously given much consideration to. Bravo Brian and credit to RSGB for supporting a project that could bring heightened respect to the radio amateur community in the UK.
So, I'm 38 and passed my Foundation exam in Jan this year (M7WKZ). Always had an interest in radio and broadcast technology but never got around to taking my test. My mother brought me an electronics kit when I was 12 or so and I went through building various projects thru the summer holidays, leading up to building a MW/LW receiver. I loved it. If I had a mentor who was into ham radio, I can guarantee I would have been hooked then! The two things that finally got me to go for my licence? The ability to do the test online (not at a club) and finding out about Meshtastic, which is a LoRa licence free 868MHz ISM band mesh based text system. I honestly think Meshtastic is an ideal vehicle to introduce people into amateur radio, the "gateway drug" as it were. I purchased 4 nodes and started doing range tests. That lead onto learning more about different antennas, what worked and what didn't and how 868MHz propagates. The more I found out, the more I wanted to learn. Each node is fairly affordable and given every kid is used to sending text messages, it's not alien to them. If you hand out a bunch of Meshtastic nodes to a load of semi interested school children, show them how it works and let them play, it'll inspire some of them. When they're discovering what a short range mesh radio network can do, then show them amateur radio and what it can do. Not just SSB voice, but digital modes, SSTV etc and if you can organise it, a contact with the ISS etc. It will hopefully inspire the next generation! Finally, I love what was mentioned about multiple subject teachers coordinating their lesson plans around a common theme. If you can have the maths teacher talking about codes, the history teacher integrating radio comms in WWII into a lesson, the science teacher talking about the electromagnetic spectrum and the IT teacher talking about how data can be sent via different means, you put a whole narrative around the subject to paint a full picture. I would also think that getting more kids into Bletchley Park and the NRC would inspire many too.
Thanks for taking the time to put this together, it means I can take my time and take in all that the video presents. A very interesting and well put together video.
Thank you Professor Watts, a great lecture- it was amazing of the skills of engineers at that time with the limited test equipment they had and the dedication to their art to make the whole systems work !!!
We weren't given the presentation to share Graham. There are links to further information on our website: rsgb.org/main/blog/tonight-at-eight-archive/2024/02/06/5-february-propagation-at-hf-what-can-we-learn-using-digital-modes-wspr-and-fst4w-by-gwyn-griffiths-g3zil/
Hi. If you email comms@rsgb.org.uk with a few details about your school (age range, whether you would like to start a school club or an after-school club) we'll put you in touch with someone who could give you some advice
Excellent video, our local radio club showed it to a group of Venturers tonight and it was very well received. By the way, isn't it sad the number of whingeing miserable hams who make idiotic whining comments, and as a result demean the hobby instead of supporting it.
I've had 8 years of not being able to use 160m to 20m and another 2 years before that when 30m was wiped out. Now we've gone to fibre on 9th January. On the 13th the 41m band sounded quiet so I checked 40m, and the other bands, all quiet. Hooray, I've got my hobby back. G4GHB.
I'd made a mental note to listen out for this expedition and then forgot. Anyway well done. Seaweed is slippery around rock pools never mind climbing upwards through it. G4GHB.
Fantastic video! there is so much to be said about grounding and RFI that would make a newbie's head spin but GM3SEK has explained it so well, it's crystal clear!
We're glad you found the video helpful. If you haven't already done so you can subscribe to our channel and get updates as soon as we release new content 🙂
Great lecture, thank you. All of this was new to me, from the development of PE coax, Sterba arrays, the Squegging oscillator... really fascinating. I'll be off now to my research rabbit hole for some time! 73 de M0MZF
