[Milsurplus] GRC-109 RS-1 antenna relay modification

[B. Smith]

       Has anyone published the  schematic or wiring diagram  for  an 
antenna relay or a pin diodes to be installed inside the GRC-109/RS-1  
transmitter on a small circuit board  to override the internal receiver 
antenna  switching circuit which has a tremendous loss aka "suck out". 
In Vietnam they used seperate antenna for the transmitter and receiver.  
The installed relay/pin diode circuit switches the antenna input from 
transmit to receive when you key on CW  and provides a pair of contacts 
for "hard" switching  the antenna from transmit to receive.  Comments 
needed of actual testing.
