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:

There is an old Humphrey Bogart movie (I don't remember the title of the
movie just now although I have seen it a bunch of times before) and
Humphrey plays the part of a bad guy in the movie and they are going to
steal the payroll from a gas plant.One of the crooks buys a tractor
tanker (sort of like an 18 wheeler) and a guy who is playing the part of
one of the crooks,but is really a copper,installs a radio tracking
device underneath the tanker so the coppers can trace the truck
tanker.It is a real good old Humphrey Bogart movie.
