[Milsurplus] What was TRC-1 used for?

[Al Klase]

Clete,

That had to do with the fact that a TRC-1 had 1 TX and 1 RX, i.e. no 
spares.  Some of the other configurations, TRC-3 (?), included redundant 
stuff.  I'm sure we ran TRC-1's 24/7, but if you had a failure you had 
to be prepared for an extended outage.
