RSGB, thank you for the consistently outstanding content and intellect. You are always raising the bar for this wonderful hobby. 73

I built a 40m qcx mini, a paddle and an EFHW in the summer. Didn't manage to get out and try it for various reasons. Watching this has given me motivation to have another go. Many thanks for an interesting presentation. 73s M7TWC

As an M7 who also has an active interest in Astronomy, this is certainly something I'd like to eventually get into... so ta for this. 🙂

Wonderful presentation! Indeed, it's quite amazing how much information you shared (along with Q&A) in a 50-minute timespan. Very well done. -Thomas (K4SWL / M0CYI)

Folly.

I've been studying these loops for awhile, built one too, but in the future I want to reduce the skin effect by using silver plated conductor, a 3 inch diameter conductor to construct the loop out of. This will increase the Q, making the antenna even more narrow to operate and tune, but by increasing the conductor diameter the loop is built out of, three inches diameter will help increase the bandwidth, six inches even better. If running U.S. QRO, the magnetic field intensity can be hazardous, better not have the loop near you. Even at 400 watts power I wouldn't want to be near it. At 14 MHz, the silver plate should be at least 2-3 µm thick.

Gotta love Dr Bruce on QRP. Gm5ddx

Excellent thank you very much for a very inspiring talk on QRP operating. Hi I'm Paul call sing HS0ZLQ, G0MIH. Yes you gest it I live in Thailand these days. The problem here is it's not as simple to operating QRP or portable for two main reasons. Firstly getting RF out from here seems to be very difficult as the propagation is very strange here it's like a black hole and it disappears somewhere never to be heard again and secondly nobody runs QRP here for that reason. Being QRP man myself it very difficult but I'm still trying with the QRP equipment I have build so I'm not giving up. Like you my age and eyesight is not favourable these days same for programming I can't do it. Anyway many thanks for your very encouraging chat. Best 73. Paul. Thailand. 😊😊😊😊

Excellent presentation! 73 from KB2GHZ.

Well done! Thank you again RSGB. 73

Not a contest fan and in 50 years of being licensed never used CW (I did have a PO class 1 ticket as a maritime RO/electronics officer in my youth); voice and digital modes, starting with RTTY on Creed 7’s (professionally) and now things like JS8call, etc. on low power are for me!

Give me a good CW contact any day. Never had any interest in digital modes.

Firmware not open I get it, quality and QRP reputation's being on the line with Open source.

Hi Ian Great talk - many thanks! Regarding use of pan/tilt (el.az) mounts, yes these can be very useful indeed for short range QSOs, Also, Airscout can output el/az data to PST rotator, so your directional antenna can track the aircraft. Have used this over highly obstructed paths up to 100-200km where there is no chance of a direct QSO. The accuracy of the positional information is good enough to be able to use a 2.4m dish on 10GHz. Had several S9+ SSB QSOs from here with OE5JFL (our local AS Mentor) over a 100km path from the bottom of our valley location. I believe a DL station has now added the ability to track the Doppler shift over a given path also, so you are not constantly keeping the CW or SSB in tune. Also, you don't have to be reliant on AIrscout if you install your own ADSB receiver. Usually a simple cheap dongle and suitable software will get you going independently. Q: are the pink coloured aircraft the one to choose? You may have mentioned that and i missed it. 73 Charlie DL3WDG

We listened for several German and Czech beacons today on 2.3Ghz. None or very faint direct path, excellent aircraft scatter paths. 73 and thanks for the talk Ian, de DL4KGC

These should be RSGB related, not a personal vlog channel!

This is what an exceptional teacher / mentor looks like. Thank you John Hislop and the nice folks at RSGB for sharing this fine presentation. 73

Good stuff!

This young lady's diction needs some work - it's difficult to understand her at times.

Wish you all the very best 👌 👍 De VU2RZA

Nice presentation 🎉

Nice- I like it- 👍📡KE2AUM-73

This was awesome and very inspirational. When out portable it often brings us in to contact with inquisative members of the public which give us our chance to promote the hobby. Portable events like POTA, BOTA and Sota bring so much fun to our hobby and this type of activity is crucial if we wish to bring new members in to Amateur Radio. April gave a great presentation here I was so glad I was there. Many thanks to the RSGB for sharing this on You Tube.

Great to see this becoming recognised as important again.

Wow! Thank you to the rsgb and to all the people involved in this video students radio amateurs wonderful. This is a good way to introduce new life into the hobby. Wonderful! I applaud I I applaud with so much. It's a wonderful world Is amateur radio best 73s G0HDA

OoooOOOooo ... It's nice to see a KZbinr you follow appearing on these lectures 🤗

I wasn't able to watch this live but wanted to add my thanks to Tim for an informative and easy to follow talk. I picked up some great ideas for mobile operating. Thanks too to the RSGB production team who put the show together. Ace G0ACE

Great presentation Tim! 👍 Thank you RSGB for making these presentations available to ALL via KZbin. 73

What is the 1-bit sample rate? Is it high enough to get THD ubder 1%? It soumds like the 2nd harmonic is supressed enough to run the output into a linear amp (unlike the uSDR) Is there a sequencer output?

Superb lecture. Thank you RSGB. I hope ARRL is watching and taking notes. 73

Thanks 🙏👍 for inspiring tale of the dawn of global radio❤ communications❤ gb2nz❤

You did an outstanding presentation. The only suggestion is to make sure you pronounce ChatGPT, not gtp. Sorry for the correction. It just distracted me too much. 73 and all the best. Luis, HB9HJU

aRSeGB doesn't care about Amateur Radio, only their book selling business bank account.

Where are the Wherthers ?

Why not just stop selling books and trying to encourage Children in to a hobby where they can sit on the old ages pensioners knees, and start actually looking after the RADIO HOBBY you represent. the aRSeGB do NOTHING for UK Amateur Radio but only for their own bank account, when will people wake up and see this is a LIMITED COMPANY who's main business is SELLING BOOKS..!! 56:20 wants more women....he needs to get a woman..and a diet. are there not enough women in this MANS hobby...bear in mind most of them used to be men anyway.

Thanks 🙏👍 for great presentation.😊❤

RSGB does not seem to realise that marketing is done differently these days. For example, younger people tend to follow social-media ‘influencers’, of whom PROMOTE by associating themselves with a certain product/hobby/skill/opinion/trend online, via social-media (usually instagram). Fashion marketing is mostly done like that nowadays. To promote the service of ‘amateur’ radio, which is more than a hobby, as proven during WWII, it only takes a celebrity or two to demonstrate how ‘cool’ it is, expressing (their) enthusiasm for wireless radio. I very much doubt that the RSGB team know how to make wireless radio cool. Collaborations between two forces is a very common mode of promotion now too. Promotion via remote events full of overweight, gatekeeping, patronising old ducks? I generally don’t think young people are attracted by that. Why does the RSGB team mostly consist of people (men) over 50? Amateur radio is becoming like train-spotting. How many of the RSGB did apprentices to train for their careers? Apprentices seldom exist now, young people are generally hated by British old folk, ignored and left to struggle by themselves. Thanks a bunch, pull your socks up, baby-boomers are the most privileged (and happiest) generation on record. I am a non-member of RSGB because it is far too expensive for me. It seems that RSGB membership is priced towards pension collectors, which may reveal the face of the whole problem. The average working person simply can not afford the RSGB subscription fee. I wonder if I will ever want to join such a clique, do change your attitudes …

A 120-63 ferrite doesn’t seem to exist. (At least not on any of the many specialist ferrite and general electronic suppliers I’ve looked at. Firstly, the closest types available are 61 and 67 - no 63s in sight. Similarly, sizes seem to be based around quarters (or possibly eights) of an inch so there are 100 and 125 but no 120. Have I missed something or is that number incorrect. Also, is a 125-61 likely to have suitable characteristics or will it be radically different?

This was a wonderful presentation. Very enaging. I took notes of all the books and ordered a couple to get reading asap. Can we buy Mike's book in Ireland? DE 73 EI6JHB

Fascinating presentation. Amazing work by Mike unearthing the great work of his father and colleagues.

Nice inspiring video. Let me hope that schools in my region also will 'grow' YOTA! I had the opportunity to start a club and club station at my college while I was a postgraduate student, nearly four decades back. Couple of the then YOTA are currently in UK, but 'off the air'. 73 de Jon, VU2JO

So much to love about Hans' designs. QMX+ seems to be a repository of all of them!

Generally its stupid capitalistic Propaganda which have nothing to do with reality. There is very few young ops on the bands today. Contrary to this I remember times when we had in Communist Poland 600 club radiostations and 3.7 MHz subband was full of voices of 16 yrs ops...

Thank you to the RSGB and everyone involved for their help and for sharing this video!

Really great to see so many young people coming into the hobby...well done all

Thx for posting

Thankyou very much for this excellent video! just passed foundation .. loving it so far

There's more need for RAYNET than ever.

Excellent presentation and Talk and I agree with most of the suggestions except a single test, due to the levels allow progression through the various levels of difficulty. I did my morse, but for some getting the B licence was enough and many didn't go for the morse due to finding it difficult yet it did not stop them from using radio, though they were limited to 6, 2 and 70. One test could produce a lot of failures and disappoint many people who want to get on the ladder. But I must agree, change or more options should be offered, including Morse as a bridge to Full Licence including others. Different pathways would be better for all, differentiation is the key here I think. People's learning styles are varied, and we should enable them to take a route preferable. Tommy M0BOC
