[ARC5] [Milsurplus] "Command Set" vs. "Liaison Set"

[Jim Haynes]

And just to confuse the issue...

The BC-366 jack boxes used in airplanes had a five-position rotary switch:
COMP (compass) LIAISON COMMAND INTER (interphone) and CALL (call on the
interphone).

The later BC-1366 jack boxes had positions:
COMP V.H.F._LIAISON COMMAND INTER CALL

Now it seems that a VHF set would be used more like a command set, and
doesn't have the long range liaison capability.  So does this marking
imply that the liaison set was VHF, or that the switch position means
"either VHF set or liaison set, depending on what is installed in the
particular airplane"?
