[MRCA] AN/GRC-106 Jeep

[KA1LHZ]

The GRC-106 uses a 4 pin power connector. There is a screw that secures 
it to the radio connector. I have some of the MS-117 antenna sections 
(not the stackable one nor the end one, the intermediate one). The large 
round connector on the left of the radio next to the 'N' connector is 
the antenna connector. It is a high voltage insulated wire that goes to 
the antenna base (MP-65)and is secured with a screw terminal. I modified 
the base to be fed with RG-213 coax so my shelter didn't turn into a low 
freq microwave oven. It's a bit squirrely tuning up on some frequencies 
but it works pretty well.
