Yes that was the way they used to send differential data most likely a
timecode signal, but also most likely not IRIG it would not have ever
needed a triax feed. Triax was quite expensive and fell out of favor about
1985.
How many of these things do you have??
Many of the old true-times like the dc goes 468 are simply nice cases with
a display. Virtually every other bit of the insides is useless. I do use
the cases for projects and typically pick them up at hamfests for $5. Great
1 rack unit case. Plus I do like the old displays. :-)
Anyhow if you do run across a True-time DC-60. Keep me in mind. Now that
they no longer work with WWVB I want to pick one up to experiment with.
Regards
Paul.
