[MRCA] AN/PRC-77 RELEY, RETRANSMITT

[Gene Smar]

Thanks, Gary.

It would be fun to try this ourselves but we'd need to find a way to 
transmit within the 6M amateur band exclusively.� TM 11-5820-667-12 for 
the PRC-77, p 6-1, states that Cable Assembly, Special Purpose, 
Electrical CX-4656/GRC is needed to interconnect the two -77s.� It also 
states that the two freqs must be at least 3 Mc apart.� We'd have to 
check for interference between our selected freqs by checking the freq 
compatibility table also in the TM above.� Lots of spurs possible with 
synthesized radios, I guess.

I read somewhere, and include this bit of info in my PPT presentation on 
squad radios, that this relay arrangement was used in Vietnam to enhance 
comms between troops on the battlefields and artillery batteries miles 
away.� The relay, I had read, was inside a fixed-wing aircraft orbiting 
at some low altitude between the battlefield and the artillery.� Can 
anyone confirm this from his own experience?
