[ARC5] T-17 goes for big bucks!

[Chris Bowne]

Outside of figuring out connector pin out differences between the SCR-274 and the ARC-5 transmitters, the only change I had to make to use the ARC-5s with the BC-466 screen modulator was to change the value of the ARC-5's 1625 screen dropping resistor to match the one used in the 274's.  Been running them that way for many years now.

Already had two transmitters, the ATA two transmitter rack with the circle M morgue stamp from Gordon's collection and mount, modulator and mount, and a really scruffy control box missing about 90% of its paint. Three ARA receivers and a 3 receiver shock mount with Command set rack and control box. The ARC-5 stuff is equally incomplete.
