R 1082 pre war aircraft receiver.

R1082 receiver,

A real museum piece.

The receiver is all original from the out- and the inside.

Just like the R 1116 receiver, this is also one, which is a very scarce radio to get. A very simple design with only 2 tuned coils to determine the receiving frequency. One  for the HF stage, and one for the detektor stage. It is also, like the R1116 receiver, one of my favourite radio’s of my collection.

The R 1082 is a prewar aircraft receiver, used with the T 1083 transmitter. It is a TRF receiver , with 2 single coil  for each frequencyband.  One for the HF stage (below on the front) and one for the detector stage (above at the front). There are various freuqency wavebands.  The receiver could also been used for directionfinding purposes. For DF, at the head of the the HF coil, there is a symmetrical inputconnection for the cable of the loopearial. Directionfinding must be carried out  by means of  listing to the signal minimum. So no DF instrument. On the first picture a special (green) S-type coil (detector) is used. At the top of the coil, a spline cable for remote control can be attached. The meaning of this is only for readjusting the frequency a little bit. Only small  tuning is possible, otherwise you have to retune the HF stage also, when you make larger requency tuning.
It needs 2 volt fotr the heaters and 120 volts for the HT.

The above picture shows my receiver R1082. In front at the left the 2 volts heater battery and at the right  a couple of  coil sets for different frequency bands.

The receiver from the right side. Note  that  the aluminium case for the receiver  is put into a wooden case.

As seen above:  a close view of the front of the receiver. The cable for the PSU is homemade by lack of an original one.  The connector is made of a piece of teflon.

This is the coil set box, for the different frequency bands. A very hard to get box! Sure when it is complete and it is.

  1. Yes, the receiver is rare and so is the coil box. Have tested mine and it is quite sensitive. Have the coil box with all 28 coils, but missing the receiver tube cover.
    Will soon put it up on Ebay, as I’m selling off the WWII radios in favor of WWI units. which are even more rare.
    Thanks,

    • Hello Bjorn,
      The R1082 is a very nice and rare receiver. Mine is working too very well. I needs some handwork to let the station come through, but then you can hear it very well.
      It is a pity, you sell your collection. it will never come back. Especially the R1082 in such a condition. Maybe you offer it to a radiomuseum.Then other people can enjoy it looking at it? Otherwise only traders?

      Regards Peter

  2. Hello,
    I am the owner of the posts r1116 and 1082 which are in very good condition and I wanted to operate them (I have a 120 volt power supply), but specialties have advised against using them in the state they tell me to replace all Capacitors before putting them under voltage, if I do this the appearance of the interior equipment will be denatured it annoys me, what do you think as a specialist of this type of radio?
    Right now I’m rebuilding a Lancaster fuselage with all its original radio equipment, I can send you pictures if you’re interested!
    I live in france in the valley of the loire.

    • Hello Jacky,
      The R1116 and R1082 are real museumpieces. The are very rare!
      I never would replace these capacitors. I also did not do it in mine. I would give it a try, to let it work. Slowly increase the high voltage and look at the current of the psu. Mine was working good without replacing the capacitors. If you replace them, the value is decreasing a lot, so don’t!
      Remember to construct a battery for the negative voltage (BIAS supply)
      You may send me some pictures, thenk you.
      Regards Peter.

  3. Hello Peter,
    Thank you for the information, I will not replace the capacitors and will proceed with a progressive voltage, I will send you photos at the beginning of the year
    thanks again.
    Best wishes
    Jacky

  4. Hello Peter,
    I wanted to send you the pictures of my WW2 Airforce radios but I can not join the files, do you have an e-mail address?
    Best regards
    Jacky
