[MRCA] MRC-55/GRC-14 Radio Set-Up: Anyone have any history on this unit ?

[DSP3]

I don't have an official history but the GRC-14 was the Marine Corps 
answer to the Signal Corps GRC-19, both RATT rigs.  The receiver with 
the GRC-14 had the RTTY converter built in and supplied the loop current 
to the terminal unit. What looks like an S-meter is the tuning indicator 
for RTTY signals.  The receiver is "fair" and pretty broad.  The whole 
mess is much heavier than the GRC-19, I think and a bit more 
complicated.  I've had some of the equipment, to include a couple of 
receivers.  They are all gone, now.  They are post Korea and appear to 
be about the same vintage as the GRC-19.  I never did see any real 
quantity of GRC-14 gear on the market or for sale by DMRO or GSA, etc., 
just a few receivers.
