[GreenKeys] R-808 military receiver with built in TTY converter

[WA5CAB at cs.com]

AN/GRC-14 was a USN/USMC competitor to AN/GRC-19 or more correctly to 
AN/VRC-29 and AN/GRC-46.  Similar generic specs.  Differences are that FSK 
capability was built into the transmitter and receivers. there were two receivers 
in the sets. and theyt weigh far more.  AFAIK, the only manual done was the 
2" thick (in two volumes) NAVSHIPS 92911(A) on the AN/MRC-55 (AN/GRC-14 plus 
M38A1 with built-in auxiliary generator).  

The R-808 receivers are electrically and functionally similar to the R-392 
(no HV) except that the FSK converters are built in.  They are a little 
heavier but not too heavy for one person to move around.  They are reported to 
work about as well as the R-392 but have analog dials.  The receiver is a 
hybrid (mix of tubes and transistors).  The first 115 sets (according to the man
ual - as there are two receivers per radio set it should have been the 
first 114 or 116???) had audio discriminator type FSK converters.  The balance 
had IF converters.

Due probably to the weight, very few complete AN/GRC-14 and AFAIK no 
AN/MRC-55 sets have survived.  But a fair number of receivers have.  About a dozen 
years ago, I extracted all of the R-808 information from the AN/MRC-55 
manuals and called the resulting manual NAVSHIPS 92911(A) (R-808).   Reprints 
available for $30.60 plus shipping.  Heavy covers, 196 pages, 14 foldouts, 
screwpost bound.
