I have made a website about this radio. www.la6nca.net/homebrew/matchbox/index.htm Uffda, Oscillator bias resistors is missing in schematic in video. It is right on this page. R and T on xtal have also been swapped.
@LA6NCA if you could publish the dimensions on the various coils used on your homebrew projects would be fantastic for those of us without 3D printers. I have a No.48 set I would to get up going it is only a case of getting my self organized. Always enjoy your content I am also learning CW so your sending I can copy a little bit. I like how you write down what you are going to send must help with your sending. What speed do you send at.?
Awesome as usual. In Australia we have a person who also does homebrewing, and often with second hand parts. He is Peter Parker VK3YE and also on RUclips. Both you and Peter are very inspiring, especially in terms of showing that great communications can be done on the cheap. Thank you again for showing.
Hi Helge Your videos are fantastic and we love your Norwegian accent...your English is excellent !!! Please continue to do your own voiceovers ...it is your individuality that makes your videos so special!! 73 Steve W8SAW aka G4DFN
Very fun video! It's amazing that you can do so much with so little. It's also neat to see how excited you were to see it work. I hope I continue to have that kind of enthusiasm of my whole life! Your English at the start of the video was good enough that I don't think you would have needed to use the voiceover.
This would no doubt win the homebrew contest at the AMQRP 'five days in May" gathering of the AMQRP society the weekend of Hamvention in Fairborn Ohio. Bravo Helge and73.
Are you all fond of AI text to speech used for the commentary (with a strong American accent)? I would have liked to hear the guy's voice: at least he is real and authentic.
Thanks for the comment. It was easier for me to do it that way. It is not so easy to speak without a strong Norwegian accent. Many from Norway have this (Jens Stoltenberg in NATO) I get to practice a little. Some have liked it and say that they can better understand the video.
@LA6NCA This is very astonishing, with 0,3 W, and antenna only 1m high. For your AI translator, it's OK, but your Norske aksenter is not difficult to understand. Even when you speak Norsk, it's so close to German, I get 50% without translator. 73 from F1VEL ex DB3YZ
Fantastic!!! I thought that you were only dealing with military boat anchors but no, you are an amazing integral han radio operator. Thanks for the inspiration. My smallest one has been on a Altoids tin Can and also on a tuna tin can. None of those my own design. Congratulations!!! The antenna is very cool and simple too. NVIS at its maximum expression even the band choice is optimum for NVIS. A hug from San Salvador. 73, Rob, YS1RS
I love the small, compact rig. The only issue I would have is using the small key. Not having a sidetone is not a problem for such fairly basic circuits and 0.3 watts is plenty enough as I have been strictly QRP for years while using only dipoles and end fed wires. Take care and 73 de wa4jat
Amazing. Envy level through the roof. Please, next time bring a comfortable chair, small desk with a lamp and a bottle of The Good Stuff or that cheap cherry wine they make up there that us teens prized back in the 70s. And Ann Margret.😊
Your English is wonderful. Your diction is excellent. Both better than many of my countrymen, probably including me! Regards from Peter, Sheffield, UK. PS. I was very disappointed when the AI voice kicked in, but your content is very interesting.
Thank you for liking my English. But it is not so easy to get everything I want to say said in English. Alternatives are Norwegian with subtitles. After I started with AI voice, the number of viewers has increased considerably. I get to practice a bit in English then too.
Hi Helge I really get inspired by your work, and insight also about old ww2 radios. I got my license now. I hope I one day can achieve something like this. But for now I should probably buy a radio first and get on the air and build later.
Amazing. Thank you so much for sharing this. I may have to break out my soldering iron to replicate this beauty. All you'd need to add is a fishing pole and a small tackle box with lures, a candle and some tinned meat for lunch and this beauty would be exceptionally covert. I wonder just how much smaller this could be made with SMT components. Thank you. You gave me the first smile of the day. Be blessed.
Thanks for the great comment. Check out my website if you want to build one. I will try to build one with SMT components, so we'll see. www.la6nca.net/homebrew/matchbox/index.htm
Hi thank you very very much for this video I am non-sighted so I have no vision I loved the audio description!!!! it meant I could follow the video perfectly thank you very much Joe
Nice spy radio. Very interesting antenna used by Finnish special forces operating behind enemy lines during WW2. Very brave men and women. I think there was some amateur radio operators at the time helped with the development of radios/antennas used. Great video to learn from. Best Wishes.
Thanks for the info. I have made a video about the KYYNEL that was used in the Finnish winter war. Out in the video you can see the antenna (from 5:30). It is such an antenna that I use in this video. ruclips.net/video/zzj-VWrDq1I/видео.html 73
Good to hear, you should build a normal sized one first. Check out my website for more information. I had forgotten two resistors in the drawing in the video. 73
Fantastic! I cannot believe how well that worked. Your "micro circuits" are really impressive. Especially the little coils next to the op-amp. How long did it take to design and build it?
Oh it's that why i never got my shortwave radio to work? It has a giant antenna on a spool but i didn't know you had to have the whole length out like that,or however long it needs to be. Maybe the antenna was only 12 feet
Fantastic material. Congratulations! I'm adding this video to my favorites. In my free time, I might try to build such a mini radio station. I was interested in the information about agents using such antennas during the Winter War. Can you devote one of the next episodes to this little-known historic topic? This would also be very interesting. Greetings from Poland.
Thanks for the great post. I have previously demonstrated this KYYNEL radio. ruclips.net/video/zzj-VWrDq1I/видео.html At 5:30 in the video, I show the antenna. It is the same one that I use in this video. 73
Thanks you for your comment. The mixer is the ADE-1ASK or ADE-2ASK from Mini Circuits Many other mixers from Mini Circuits will work. Just look at the data sheet that they are designed for frequencies as low as 80 meters. Remember that I have left out two resistors in the drawing in the video. Look at my website. 73
Man, You Are The REAAL MACGYVER! HANDS DOWN! Is It Possible That You Can make Such 80 meter Bugg Or 40 Or 20 meter Tranceiver? Not That Small, I mean, Whatever Size.. :) ;D
Thanks for posting. Yes, it is possible with this design to build for all radio amateur bands. This mixer goes up to 500 MHz. The transistor in the transmitter is also a GHz transistor which will take all HF bands.. One can also replace the oscillator with an SI5351 circuit. 73
The transceiver is quite similar (although smaller) to those Chinese Pixie kits that are sold very cheap on e-Bay and Ali Express . They operate on 40m though, at about 500mW, and can work distances of several hundred kilometres. I wonder about the Morse key. Did you make it yourself? I'm glad that I could read LA5MT's Morse, as mine is rather rusty. ;-) Best 72 es 73 de GØOIW
Thanks for the video, some great skills on display. The antenna is very interesting. I will subscribe in the hope you put up the details. I would like to try some nvis 73 Will, VK5WB
Great video and definitely a cool transceiver that you made. Can that style antenna be used for 11 meters Sideband if it is cut to length ? Also, I really enjoy the video in English 👍🏼
He is using NVIS (Vertical Incidence) coms in the low HF bands, however there is little NVIS at 11m. The antenna would still work for ground wave, but is too low in height to be much use on 11m.
I first write subtitles, then I export the texts as subtitle files. I transfer these files to AI generated audio on the internet. Then I cut up this audio and place it under the texts in the video.
I have made a website about this radio.

Thanks for the great comment.
It's fun to read the comments.
Congrats for this QRPP achievement Helge, amazing results. Best 73 from Germany.
Congratulations on the QSO and thanks for sharing the video. Your work is an inspiration to us radio constructors!

This coil is 3-D printed. I can later post the files on my website.
It is easy to build when you have such a coil form.

*Hail!* Perhaps next life i will understand more, until then, this was Great! *Cheers!*
This is a perfect example of why amateur radio operators should still learn and practice using Morse code.
Yes, CW is very effective.
On the day I made the QSO, conditions on the band were very weak. The signals still went through.
This is brilliant for SHTF 👍🏼👍🏼👍🏼
What is SHTF?
@@LA6NCAacronym for when the Sh*t Hits The Fan, in other words when things go bad.

Yes it is very exciting I was so excited I paused the video to write this and then moved on to a different video
That is amazing, would love to be able to build one.
Great,
Look at my website.
Forgot two resistors in the drawing in the video.

I first write subtitles, then I export the texts as subtitle files. I transfer these files to AI generated audio on the internet. Then I cut up this audio and place it under the texts in the video.
Thats awesome!
I'm sure I read in an article the OSS during WW2 told operatives to use fence wires for dipole aerials, they could be miles in length,
Amazing! QRP!
