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

[William J. Neill]

AN/FRR-40 and AN/FRR-41 were used for MUX purposes and used either  
stock R-390 or R-390(A) receivers in CY-1119A rack mountings.   
There's nothing special about them.

As information, SigC described a series of equipments based upon the  
R-390( ) in the following Technical Bulletins:

TB SIG 322-173  SSB Voice Terminal Equipment		06-10-68
TB SIG 322-174  SSB Channel Combining & Splitting Equipment	06-10-68
TB SIG 322-175  HF Radio Direction Finding Equipment	04-09-71 (AN/ 
TRD-15)
TB SIG 322-178  SSB TTY Terminal Equip 16 Chans		06-10-68 (AN/FRR-40/41)
TB SIG 322-301  Diversity FSK TTY Receiving Equip		11-29-68 (AN/FRR-38)
TB SIG 322-302  SSB Receiving Facility				11-29-68
TB SIG 322-303  Basic HF Radio Receiver (R-390)		04-15-69
TB SIG 322-306  Facsimile Terminal					08-21-68

I have originals of the above listed documents in my collections.

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.
