I can't imagine anyone would have had the courage (or even any reason) to photograph these vehicles, but are there any references/images of vehicles used by the occupying Germans to detect illegal radio transmissions?

You mean this type of truck ?

Here's a movie prop one, based on a Czech Praga RN truck :


Don't know if it's accurate or not...

Excellent ... thanks!

that would make a great surf wagon.

I would assume (big risk there) that they would use the same/similar vans (panel trucks) as those used for propaganda work with the big speakers on top such as the lite Opal vans, etc.

I think the top picture in Frenchy's first post is a movie mock-up from "Heroes of Telemark". You can always tell the movie ones because they always insist on putting big black crosses on things, which was almost never done with softskins in actual service. The loop aerial shown in the other pictures looks more likely to me. Inside were probably surveillance monitors commonly issued to Wehrmacht signals regiments, each one of which had a special listening group. There were six receivers: Fu.H.E.a-b-c-d-e-f. In addition were the MEFA IV, Fu.H.E.v and Fu 14. For more information see Wings and Wheels Publications No 10, "Wireless for the Wehrmacht in detail". This also covers vehicles including temporary radio vehicles.

I agree. I've just posted it to show what Paul was talking about.

Here's a larger view :



The enlarged second picture :



Looks like a Kfz 17 variant.
