Torn Fu's

[Funksammler]

I finally managed to get some of my stuff displayed in my new display room. I set up a "Tornfunk corner" with (left to right): Torn. Fu.f, Torn.Fu.b1 and Torn.Fu.k. Note the difference in the battery case of the Torn.Fu.k, instead of the usual 2V battery and Anode batteries, this had 2 x 2.4 NC 58 batteries and a vibrator power supply. I also displayed the "Fernbesprechung" in front of the Torn.Fu.b1, in real operations, the reel on the left would be taken up to 100 m forward to a concealed observation post.

Here is a nice late war Dora in a temporary display. It is placed on top of the Fu 71 "Vorrat" box, which contained spare batteries etc. In front is the "Abgesetzte Antenne", which would extend the range of the set somewhat. It also allowed the Dora to be placed in a underground shelter with the antenna outside. The coax cable was also used to connect the set to the vehicle antenna when placed in the Kfz 2 radio car. I will probably take some pics of the setup fully deployed in the garden later this year

outstandig collection, i love it

[Funksammler]

The b1 and k should be working, at least they did work some time ago. The vibrator in the power supply of the k may need some TLC... The f and d2 are relatively recent additions, I haven't had the opportunity to test them yet, but I am confident they can be put back to work.

One interesting fact about the Torn.Fu.f is that the tranceiver and Zubehoer box have consecutive numbers, this set has been together since it left the factory in 1942!

Very nice !
Is it known how the Germans worked with frequencys?
Did they transmit on freq A and receive on B or was freq A = freq B,.. ?

Normally they would work a single frequency. Dependent on their tactical use they would either be tuned into a net or they would form a line connection. For example the Torn.Fu.f was primarily used for artillery observation, a single observation post could direct fire for a specific battery and would be assigned a specific channel. Radio's for more general tactical use like the b1 or d2 might be netted into a battalion or regimental net.

For a given time period the crew would be given two frequencies, one main frequency and an alternative frequency in case the main frequency was jammed or unuseable. For this reason you find 2 "Rasten" or presets on the transmitter part of the Torn.Fu.b1/c/f/k and the d2. In this way the stations could switch frequencies quickly and in total darkness if nescessery. It was normally the responsibility of a signals officer to assign the frequencies.

Generally transmission was only allowed once contact with the enemy was made. During movements, preparations for attack etc. strict radio silence was to be enforced. It is possible that in times of radio silence, the crews were monitoring specific alarm frequencies.

The tactical use of these radio's is definately an area requiring more study; the German army had many different "Funkvorschriften" detailing the use of radio's for different branches. These may have been revised from time to time based on practical experience. From the ones I have been able to study, the principles of their use appear the same but details may vary from branch to branch.

Thanks Funksammler, this answers already some of my questions.
