[TMC] Tele-Signal Corp TTY converters

[Duncan M. Brown]

Haven 't had a chance to look at the Tele-Signal units closely yet.  

Concentrating on getting the SBT-!KV running first.

Does the 102A receiving converter perchance have two audio inputs?

For RTTY, there is a TMC TIS-3 and a TMC PSP-2 (dual TTY loop supply). 
There is also  a "F. S. Tone Transmitter Model 101A", a "F. S. Tone
Receiver Model 102A", and a "Transistor Switch Model 109", all made by
"Tele-Signal Corp."  (see pic)  Can't find any information about the 101A &
102A  (other than the possible patent for the AFSK generator: US3271588).
Tele-Signal was located in the NYC area.  Possibly a spin-off of TMC?? 
Anyone ever heard of them?? 

Seems strange that there would be two AFSK transmit units and only one
RTTY converter unit as part of the station. (I haven't had a chance to
follow the wiring yet.)

Any comments??
