[Milsurplus] KY-83/S keyer ??

[WA5CAB at cs.com]

Instruction Book for Keyer KY-83A/S.  05/18/1953.  My note was correct.  
The keyer is used with UHF transmitter-receivers (mentioned are TED/RED, 
TDZ/RDZ and AN/ARC-27).  A Mine Sweeping Auxiliary Control Panel on the Master 
MSO (Mine Sweeper, Ocean) generates a 500 CPS signal which is sent out like a 
string of slow Dits or Dahs.  Transmitt audio and the 500 CPS keying pulses 
are passed thru the KY-83 where where a 500 CPS filter/mixer section strips 
out voice signals around 500 and inserts the keying pulses.  On the Slave 
MSO's, a similar filter strips out the keying pulses and routes them to a 
Slave Auxiliary Control Panel which is connected to the sweep gear.  The rest of 
the received audio is routed to a loud speaker or SB-82/SRR or equivalent.

The KY-83 cabinet is built similiarly to say an AN/URA-8 or 8A/B.  Grey 
with rounded corners.
