[GreenKeys] TMC Terminal unit: TH-39A/UGT aka TIS-3

[Roy Morgan]

Greenkeyers,

Has anyone worked with a TMC unit:  TH-39A/UGT. The Tag says "Terminal, 
Telegraph."  The civilian name is TIS-3.

It generates audio tones shifted from 12 to 1000 cps, centered on a 
selectable center frequency.  It's meant to feed any SSB transmitter at the 
audio input to implement RTTY

I recently got one and expect to use it here with the rest of the TMC gear 
I have (including a GPT-750.)

If anyone has a manual, I'd VERY much appreciate a copy.

Roy
