We had a TIS-3 on Guam - which served us very well there - 
then in Newport News, VA - where we used it (believe it or 
not) on CB.  If anyone is interested I'll tell the story of 
how that came about... but only if- as I don't wish to bore 
folks.

Anyway when I got out of the Navy early 1978 - some of  the 
others that regularly participated in CB RTTY net in the 
Tidewater region approached me about buying some of my gear 
- and the TIS-3, along with both Kleinschmidts and a bunch 
of other gear stayed with new owners as Sherry and I moved 
to Mississippi.  As noted - we've regretted letting a lot of 
that stuff go since - and are slowly re-building.  To that 
end - I have a saved search for Technical Materials "stuff" 
- and sometime back a really nice TH-39B showed up - with 
not much of a description, etc.  I managed to snag it.  The 
TH-39B/UGT was the last of the TIS-3 series -- used in the 
AN/URT-19, AN/URT-39, AN/URT-40, etc. I think I was really 
lucky - as the last TIS-3 I looked at before that was in 
pretty rough shape and went for considerably more.

They are sweet-hearts -  easy to set, etc. - and when their 
output is fed to a reasonably stable SSB transmitter - drift 
is negligible.

So while I agree - a complete unit would be preferable - I 
still think it would be worth the effort to salvage the one 
you have.

best regards (and good hunting!)
