Hello

I am working on a tv mini series that takes place during WW2. We are trying to find what I'm told is a "rebecca-eureka" transponder system. I'm attaching an image of what we need.

Thanks so much

I don't know where you can find it, but this is what you want:

The Eureka is a small US ground unit, RT-37/PPN2:

There was an earlier RT-44/PPN1 (1943), also called Eureka, but your image shows a PPN2 (1944).

This is a British Rebecca MK 2, which may be what you want:

This particular unit was in service in 1945, so it is possible it is contemporary with the PPN2 which appeared after D-Day (June 1944).

It's considered a radar transponder because it provides azimuth and range. An aircraft transponder generally provides identification.

You might try Fair Radio in Lima Ohio.

Here in NZ we still had 200MHz DME in the early 80's but they were slowly being replaced with the 1000MHz variety. Not used as IFF any more of course but the DME bit worked well but it did suffer with the low maximum number of aircraft - ISTR it was only 20 or so within the 200 nm range. On our calibration aircraft the units were made by Murphy (no, not the Irish Murphy!) specifically for the DME so only one unit plus the displays - they were usually co-sited with a VOR so as soon as the pilot dialled in a VOR frequency, the DME was set to the ICAO corresponding frequency.

There is a good write-up in Wikipedia about the development in the early 1940's
