[R-390] R-1247 Nasa Receiver FOR SALE

[rbethman]

Dick,

No they didn't fly them.  There were a bunch of changes to these by 
Manson Labs.  There are a bunch of Bnc connectors on the rear panel, 
that allows for a higher level of frequency control and coupling them 
together.

Uncle Sam's methods of "coupling" R-390As was done externally by 
receiver multi-couplers, directed at the diversity aspects.  When you 
start doing HF operations for a Space Program, the diversity antenna 
systems that Uncle Sam used for intercepts no longer would work.

Hence the major mods done by Manson Labs.
