[GreenKeys] UGC-136

[Nick England]

I dunno - I haven't ever had a UGC-129 - but the capabilities look similar.
The UGC-129 manual I found on line is an Air Force TO but has what looks
like a 1977 Navy contract number - weird
TRACOR, INC.   N00038-77-C-0077
Did the Navy fly them aboard P-3 Orions?

Probably the Navy needed something that was gray and twice as heavy for
ship/sub ballast?

The military era between mechanical machines (Model 28, Kleinschmidt) and
PC/LCD seems awful schizophrenic to me.
Lots of versions with essentially the same features.

Huh - I found this in a 1986 DCA report on UHF SATCOM -
"A prevailing problem is the teletype ASCII character length where the Navy
uses 7-bit and the Air Force uses 8-bit"
