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

[Doug Hensley]

Robert, see the ePlace item 161828753222.  These are certainlyaround but they may be beyond the skill level of most radio people.  The MRC-55/GRC-14 set up is pretty challenging stuff.  

<< Due probably to the weight, very few complete AN/GRC-14 and AFAIK no AN/MRC-55 sets have survived.>>I have some spare R-808's if anyone is interested.
