[MRCA] URC-35’s

[Glenn Little WB4UIV]

When I was in Navy MARS, I was assigned to the 6th ND directors office.
Each director was issued at least one of these, new in box.
I uncrated it and used it for voice communications.
Being curious, I requested additional information on this set.
I wound up in communications with one of the designers of this set whos 
mother also used one for Navy MARS.
He said that the radio was very unreliable due to the heat density that 
was a result of the design specs from the Navy.
He said to cool the radio for long term use you had to drill a lot of 
cooling holes in the amplifier cabinet.
The radio was never deployed on war ships, IIRC, it was only used on 
auxiliaries such as tug boats.
The radio id basically a R-1051 and a low power T-827 in the same box.
IIRC, the RT puts out 10 or 100 mW to drive the amplifier.
The amplifier cabinet contains a 100W PA and the power supply.

I cannot locate my manual now, but, Artekmanuals.com has a very good 
scan of my manual for $17.50, this is two volumes for AN/URC-35B.

The radio is probably as good as a R-1051/T-827 combination when used at 
low power.
I would NOT use this radio for RTTY or other digital modes.

Many modules are the same as R-1051 and T-827 modules.
