[Milsurplus] [ARC5] SCR-522

[Mike Hanz]

I suppose that's possible, but so are switch positions in a lot of other 
transmitters. :-\   I suspect the primary reason for this equivalent of 
"key down" capability available on other Signal Corps sets was for DF 
work by the extensive system that the British had in place during the 
war.  Both the BC-608 used for early aircraft IFF and fighter control, 
and general practice when bailing out, required the transmitter to be 
keyed on while busy with other tasks in the cockpit.  I think most of 
the time the switch was left in the remote (PTT) position.
