[TMC] 4htf4

[Duncan M. Brown]

We hope to have our SBT-1K up and running in the next month, with TTY.  The
system has a TIS-3 and also a "F. S. Tone Transmitter Model 101A" and a
"F.S. Tone Receiver Model 102A", both made by "Tele-Signal Corp."  Can't
find any information about the 101A & 102A.  Anyone ever heard of them??

Mark,

Good luck with it.  Want to come here and help me get  mine running next?

If you have MV rectifiers, cook them long before applying HV!

Once mine is running, I'll do some RTTY graphics tapes.
