:0 i am absolutely shocked , so nice to hear sound come from this again , i see you also have a 100Ws ww2 german radio video , im dying in my computer chair right now , thank you for making these , so excited to see more old stuff !
Thanks for making these detailed videos showing how the radios work in the field. I've seen this radio being worn on the backs of German soldiers on the front lines. So it's really very interesting to see and hear how they work.
I had such headphones when I was small (70’s), they had magnets, coil and a thin metal membrane. When we connected two headphones with just a wire (no amp, no battery), we could speak into one and hear the voice in the other with the electricity that the sound produced vibrating the membrane onto the magnet core coil..
Oh I love the 2 and 3-tube Feldfu's! Worked a lot with builds similar like them on CB (only crystal-stabilized during transmit) and UHF with a free-running oscillator and super-regenerative receiver on receive. Both jobs done by the same battery triode. Although not made to work at 440 MHz, with a max frequency of 350 MHz, the couple dozen milliwatts I got from these sets was more then enough to cross several miles of open terrain. And since it did not want to super-regenerate by grid-blocking, I had to wind a pair of 75 kHz coils to generate the quench-frequency, and than I did get stable super-regeneration up to 450 MHz. Also the back-radiation of the Super-Regenerative circuit was a LOT less when using seperate quenching coiis that generate a sine-wave instead of a sawooth/square-wave "self-quencher" (as they are called). This however ring a bit of a personal "tick" since my father was a Panzergrenadier during WW2. It's via him I "caught the bug" and now I'm still learning about radio every day 🙂 My interest in old German WW2 equipment was born out of the fact they're often quite unique designs, very strongly build yet sober circuitry. German Radar equipment is equally fascinating, and unique. Aboug gthe Feldfu: you could, if you wanted, "stabilize" the transmitter on a single fixed frequency by means of a crystal in series with the grid-capacitor during TX. This makes the signal stable enough for 10m or 11m AM-work. But ofcourse that takes away part of the originality, even though it's not that difficult I suspect. But these Feldfu's are a bit more ruggedly build than most Amateur or DIY "transceiver" circuits with 2 to 3 tubes. There's a few questions regarding the design I'd like to ask, I'll take the schematic from under the dust, and take a good look before I ask the question. Regards; Thomas ON4SPK
My father was veteran of korean war and thru him met some of the ww2 soldiers an families who were around those days.I been told on usa east coast sometimes you could pick up those panzer signals here as skip or skywave propogation wasnt fully understood let explained well yet.73s merry xmas kd5kkh
Thank you very much for a wide range of super interesting videos. The quality of the German radios is incredible. I got back into the hobby when I bought a SEM35 from eBay. Such amazing quality and construction.
Wow! This was very interesting. I have seen this radio in photos from World War II showing German soldiers using it in the field or carrying it on their back. It was really fascinating to see how this radio is operated and to also here the sound through the speaker. Thanks for sharing your hobby and knowledge for these radios.
A good idea for a short story, where the radio enthusiast speaks into the old panzer radio. Distant in the static an etherial voice answers '"Heavy fighting. Surrounded by enemy. We are low on ammunition, captain Hortl is dead." As though the combat patrol from 1944 are lost forever, trapped in the void, wandering through the black smoke of the eternal combat zone.
I expected that the Scandinavian countries are covered with snow at this time, and the cold weather will continue until the beginning of spring . Thanks
@@LA6NCA I love your channel please we need more info for Norwegian ham radios because you guys make top notch electronics . Again it would be very fantastic to snow especially in Christmas and the end of the year. Thanks 🙏
That was pretty neat. .....and it even has RIT. I don't think I'll be selling my KX2 to get one. Hi Hi Thanks for posting. I really enjoyed seeing how the radio worked. Barry, KU3X
This radio proably only had a few hundred milliwatts at best. The Antenna design on the radio was excellent. For a portable Low Band VHF radio it was first class. In ways beats he PRC9
det er flott! Tysk utstyr til enhver tid er preget av høy kvalitet og dyp innredning. Jeg liker dynamo for lading av batteriet. Lykke til og god helse til deg! Hei Fra Russland.
Yes, how do you come across these radios? History coming alive. If only the radio could talk - no pun intended! Inspiring for me to keep working towards my General License.
Fascinating radio and charging system ! Question : were the Germans the first to use a " tape measure " antenna on their backpack radios ? I did not see them on allied equipment until the 1950's ?
Even to this day, modern militaries can not make any field radio more advanced than this 1930's German Radio! Just to give everyone an idea on how technologically advanced Germany was, some historians even say Alien Technology is the reason for Germany's incredible technological advancements, true story!
H Loved the video Do you think you could tell me what connector do the headphones use I have some high empidence headphones (which I would like to use with a crystal radio I will built) with exacly the same socket The plug looks like electrical plug, and I would realy like to find the matching socket for it
Thanks for choosing such an interesting place to get on the air. A question. Years ago I talked with someone who had fought with the Allies in North Africa. He said that during sandstorms the Allies had an advantage over the Germans. Their low-VHF radios were FM and were unaffected by the static created by the storm, while the German radios, which were AM, were rendered useless. Is there any truth to that? I noticed that your German radio was AM.
Helge is Norwegian, not German. And I doubt the radio is for sale, it is part of his collection - even if it was for sale though it would cost a lot to ship such heavy gear over to Indonesia.
Yes, they could listen, but the signal does not go that many km. The signal was not encrypted. Signal intelligence could certainly get interesting information by listening to the frequency.
RIT. Receiver Incremental Tuning. It’s the receiver fine tuning control. Allows the RTO to tune the radio + or - 10 kHz to compensate for an off frequency
What is the rf power out & approx range? Can a long wire antenna be connected in place of the whip? We used to do that with the old PRC-25’s & 77’s in the mid -70’s US Army. I talked 50 km to another unit that way while we were on an FTX in the desert…

Thank you 🙂
Exciting! Thank you for the demonstration of this old equipment.
Как же здорово когда такие аппараты всё таки иногда включают, а не просто хранят в музеях )))

Great, simply great. Thank you for this video. It is realy amazing for me that these old systems are still working.
Excelente,nunca imaginé un radio de 27 - 29 MHz en un tanque alemán, algo así como la CB de la época, 73´s colega muchas gracias por su vídeo.
Helge yeah! Always enjoy your videos...73

Old school radio technology is so neat!!!!
Cool - proud of local hams. Great job Helge and Jørgen 73`s LA6YEA
Love your videos Helge...!
A great historical repository of Radio Technology no doubt...
Outstanding, Helge! I wish I had the technical skills and opportunity to bring these pieces of history to life! Keep up the great work! 73 de KJ7LLX

Thanks for this video! It's amazing!
Absolutely fantastic set up you have.
Hello sir. Greetings from Romania. I like what you do and I appreciate your passion. All the best.
Always thought Germans used FM for panzer radios, amazing they were powered by rechargeable batteries back then.
Great and hight interesting. Tnx Helge!
Enjoyed this alot , thank you.
Amazing as always!
I expected that the Scandinavian countries are covered with snow at this time, and the cold weather will continue until the beginning of spring . Thanks
Thanks for the comment.
It snowed late this year.
I'm going to make a new video with a radio in the snow.
@@LA6NCA I love your channel please we need more info for Norwegian ham radios because you guys make top notch electronics . Again
it would be very fantastic to snow especially in Christmas and the end of the year. Thanks 🙏
Nice set Helge! 73,s PD8533
So coooL !! big thank you for share this video 😊✌ 73 from Holland!!
Very nice!
Great video like usual. Mario VE3WPZ
Were can I get one sir??? Wado......... Fantastic and Merry Christmas
Important: Feind hört mit😎
That was pretty neat. .....and it even has RIT. I don't think I'll be selling my KX2 to get one. Hi Hi
Thanks for posting. I really enjoyed seeing how the radio worked.

Igjen en fin video Helge. Alltid interessant når du prøver gammelt utstyr. 73 de LA5MT.
thank you for a new video
Muy bueno, 73👍
Takk for interessante videoen! Som en tysker som bor i Norge er dine videor også en flott mulighet for forbedre norske kunskapet mitt. (y)
This radio proably only had a few hundred milliwatts at best. The Antenna design on the radio was excellent. For a portable Low Band VHF radio it was first class. In ways beats he PRC9
Nice your saving history ........ be well.
Quite a historic site Heldge. So the Panzer is primarily 10 m using ground wave mostly
This is a great place.
Yes, there are only ground waves in the panzer units.
det er flott! Tysk utstyr til enhver tid er preget av høy kvalitet og dyp innredning. Jeg liker dynamo for lading av batteriet.
Lykke til og god helse til deg! Hei Fra Russland.
Awesome setup
Yes, how do you come across these radios? History coming alive. If only the radio could talk - no pun intended! Inspiring for me to keep working towards my General License.
Não imaginava que esses rádios usavam baterias recarregáveis, nem imaginava que havia carregadores manuais. Um vídeo super interessante.

Best 73 from A71BR
Nice radio, from Brazil.
Fascinating radio and charging system !

Love it, do you have a working set for sale?
Yes, it is fun to be able to operate such old equipment.
No, unfortunately I have none for sale.
I like to know where do you acquire these radios from? Thanks an gretings from south america .
7,5 km its very short , on 10m. band
Nice
Hallopak, saya dari indonesia,sangat kagum!!hormat untuk leluhur anda❤❤❤boleh kah saya beli radionya??
Helge is Norwegian, not German. And I doubt the radio is for sale, it is part of his collection - even if it was for sale though it would cost a lot to ship such heavy gear over to Indonesia.
mooie video baas
really interesting.
What battery do you use?
It's a 2.4 Volt Nickel Cadmium battery.
I charge it from the crank generator.
Thật tuyệt!!!
perfect.. but is it crypted or something? allied soldiers could listen too
Yes, they could listen, but the signal does not go that many km.
The signal was not encrypted.
Signal intelligence could certainly get interesting information by listening to the frequency.
wounder who taught you how to operate that radio.....
What is RIT control. What's RIT mean
RIT. Receiver Incremental Tuning. It’s the receiver fine tuning control. Allows the RTO to tune the radio + or - 10 kHz to compensate for an off frequency
