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

[sdaitch at kuw.ibb.gov]

Way too far back for me to recall a lot of details, but
I remember seeing at least one Manson Labs driven 
R-390 system at either Fort Monmouth, in 1969, or
in Vietnam, in 1970 or so.

I am leaning toward seeing it at Fort Monmouth.

The July 1968 Army Strategic Communications Command
Pamphlet Number 105-4 simply calls it a Frequency
Stablized Radio Receiving Set, AN/FRR-41. It does
not list any specific unit model numbers, other than
the R-390A and CV-157. 

The detail indicates the modified receivers "will
be used for the reception of analog and data 
transmissions over STARCOM HF single sideband
radio circuits."

I had some correspondence with some folks who worked
at the Phu Lam HF station a few years ago, and IIRC,
I got some feedback they may have had some Manson Labs
modified units, but no one ever came back to me with
details or even any pictures.
