[R-390] A Group Question

[jrfke5ri at aol.com]

The AN/FRR-34 HF receiving system utilizes three R-390(*)/URR receivers in a
triple diversity configuration.  It uses a  C-1012 Control Monitor for receiver control
and selection.  It uses a KY-82/FRR RTTY keying unit for diversity signal selection
and generation of a signal for remote operation of RTTY apparatus.

I have had in my stable of gear a KEYER that I don't even remember
getting. It appears to be some ancillary piece of gear for a R-390 or
R-390A as it has the same knobs, handles and paint finish.

 

The ID plates says: KEYER KY-82/FRR

 

Can anyone tell me what it does, what it is used with and what if any
purpose does it serve these days.

 

Thanks in advance to all who respond and let the games begin ...
