Radio works great for being 87 years old. More amazing is the tuning coil controlled by strings with a built-in capacitance hat. I have never seen that anywhere before, that was very innovative for 1935 technology.
After reading a lot about WW2 field telephones and wire laying I got interested in the topic of field radios. Seems like I stumbled into the right channel, this place is radio heaven.
During my military service (1958) as radio-operator at S1SK in Sweden we use this radio one time, but the WX was very bad, in the rainy earth hi only one time we use it. Good work by you Helge 73/ from Sweden
Thank you for sharing all the information about this beautiful device. This is a very early version of a smartphone :-) I'm very curious to see how this very short antenna compares to a dipole at a reasonable height. By the way, Telefunken was a scam company that stole all of Marconi's knowledge. Morconi was forced by the authorities to demonstrate his skills to the enemies. He wasn't amused. And do you know the very first walkie-talkie? It was the Motorola SCR-536. The frequency ranged from 3.5 to 6.0 MHz. And the antenna length was even more ridiculous: about only 1 meter!
How did the Germans ensure that all stations were on frequency please? Did they have the equivalent of the UK Type D wavemeter or the US BC221? Or is the "length" of the tuning scale accurate enought to set it to a spot frequency? The ATU in the aerial is very interesting to see.
Thanks for the comment. The transmitters have frequency stops that are programmed before going on a mission. The receivers are set for best reception. The frequency scales on the German radios are exactly correct and accurate.
This was the first time I used this radio and this antenna. Therefore, I wanted to be sure that the communication would work. So I called a radio amateur nearby. Only 2 km away. The signals were almost too strong, so the distance could have been much longer.
@@LA6NCA Very good radio, 80m, 1Watt, 2m antenna, 2 km distance! I tried to find some further information about this radio, but the Torn. Fu. b seems different, and has separated rx and tx. Thank you Helge!
I use a 12 volt lead battery here. Then I have a DC-DC converter that delivers 4 volts and 135 volts. There are always better radio signals near the sea.
Ja, det var første gang jeg prøvde både radio og antenne. Var bare ca. 2 km avstand. Ble litt sterke signaler. Hadde vært artig å prøve lang avstand mot deg en gang.
@@LA6NCA Hvis du tåler en CW-QSO med en gammel rusten radioamatør (meg) som ikke leser morse raskere enn 15 WPM, hadde det vært morsom å teste 80m en gang. Jeg sender fra Verdal i Trøndelag. 73 de LA6GHA 🙂

I was surprised that all the tubes worked fine.
The antenna tuner was very interesting.
I will try to make my own.
Facinating, I do love that string operated antenna tuner! Thanks Helge... 73

Wonderful! Thank you for the video and demonstration of this portable HF set.
It wins the pounds/watt prize.
Thank you Helge. Lovely radio. I hope your thumb heals fast.
tks Helge for your time to display this video...excellent....the amazing point is the antenna radio.....73
Very nice piece of equipment and interesting "pre-screwdriver" era tuner.
73's, Patrick OT5Q
Thanks Helge for the education. I learn a lot from your videos.
Great radio! Adjust antenna is amazing!
Beautiful field radio! Excellent work! 73

Another great video Helge. That tuner from 1937 amazing.
Be safe. VE3WPZ
very beautiful and unique this 80 year old antenna design, MNY TNX Helge ES CUL, 73 SP2LNY
This is one awesome bit of kit!

Gracias Helge , muy interesante video 73s desde Chile. CA 5 FGI
L'apparato si sente molto bene, ha un audio molto corposo, bello.
Thanks for another great video
Das ist fantastisk!!
The tuner gives a good inspiration. Many thanks for the nice video. D m 1 k w
Wow what an antenna!
Great! Thanks.

that is an impressive piece of kit.. thank you for this.. 73
Hello Helge
Could you make a Video about the Lo40k39 sometime?
Thanks for that suggestion.
Then I put it on the list of future videos.
Vy nice! 73 from LZ2CH!
thx for nice video....
what have you done with your hand? get well soon!
Congratulation, Helge! 73 DE HA0NBZ frm Hungary! How long was the distance? (Leni Riefenstahl?)

It’s just fantastisk! The CrankIR must have been inspired by this ATU :) ! 73! Linas LY2H
What kind of batteries does it use ? Also, do you operate them on purpose close to water bodies ? Thx.

Fin video Helge og interessant radio og antenneløsning. Men høres ut som avstanden mellom deg og LA5UF er ganske kort :-). 73 de LA5MT.

thank you helge very nice vıdeo...73.. ta3ııd..
Muy bueno👍. 73.
Can it communicate by voice?
Yes, I want to make a video about it.
Majstersztyk Niemieckiej mysli technicznej.
What was the maximum range of this?
It operates on shortwave.
The range is large parts of Europe.
@@LA6NCA So, hypothetically, in 1936, a German radio operator with a "long" antenna could reach hundreds of miles?
You looked with great pleasure.
TKS 73!
LA6NCA de R1CBD 73 👍👍👍👍👍
it`s delicious
