[MRCA] Mobile military repeater

[Jack Antonio]

The AN/ARC-44 also had provision for retrans operation, however it was 
hardwired,  with added

relays and wiring in the junction box, not a plug and play. The basic RT 
unit has a squelch relay

included, not optional, and the manual shows the wiring and mods 
necessary to implement.

Don't know if was ever used in service.

I have a pair of ARC-44s set up, and one of the "rountuit" projects is 
to implement the

retrans. Since the set covers both 10 meters and part of 6 meters, 
should make for an

interesting experiment.
