[ARC5] Homing on Aircraft VHF Signals - SCR-564, -565, and -566

[Mike Morrow]

I found information about the ground sets used to determine direction and location of signals from SCR-522-A and other aircraft sets operating in the 100 to 156 MHz range:

All of tbese setz used the BC-639-A tunable receiver in a console, and a VHF loop antenna nearby that the operator manually rotated.  That's shown in pictures found at the above URLs.  The original text explains how multiple DF stations relayed their bearings to a central point where the signal lines of position would be plotted to determine signal (and aircraft) position.
