John,

It's a generic term for a LF radio with a rotating antenna marked off
in degrees. It was an old boating radio navigational tool. The idea
was to find two or more known LF beacons, and by rotating the antenna
to null out the signals, you could determine your position.

That sort of system has been largely replaced by GPS, but they are
very sensitive LW receivers with good image rejection.

I don't have a Raytheon model...so can't tell you anything on those.
