Subject: WW2 Radio Compass

As you know I am mad about radios, WW2 airplanes, tanks & subs.

I was thinking about getting a compass so that I could better find my
possition at home. So I did a search on Ebay on Compass. I then came
accoss something that is called a Radio Compass.
EBAY Item number: 6565758752

My guess it that the gauge is telling the pilot his dirrection in the
sky. But why is it called a radio compass?

Is the device putting out a signal? And is the signal bouncing back?

No, it's a radio receiver with a directional antenna. The display shows the
compass bearing to the radio station being received. There used to be
portable radios, usually the "all band" variety, that had built-in radio
direction finders (RDF's). Heathkit even had one, though I don't recall the
model number.

One of them was the DF-1:
