T&T: C-Swing, the Compass Adjusting Program

[Bob DeGroot, DCH]

Sure wish we had something like this when I was swinging compasses on our
USCG flying boats 40 years ago. We'd take them (Grumman Albatross - HU 16E)
over the big compass rose painted on a concrete slab just off the taxi way
and round and round we'd go.

And we used those little cheap portable AM radios as a way to check the
calibration on our radio direction finder. You remember how holding the
radio at a right angle to the station gave the best signal. Just need to
know where two stations antennas are and bingo you found yourself and it
still works today if you can find a cheap little portable AM radio with the
crummy antennas.

While doing some research on magnetic compasses, I ran across this.
A demo version is available.

I haven't tried it, but if you are bored...
