[R-390] R-390A Question

[quartz55]

I worked for the 78th USASASOU in Berlin from Nov 63 to Nov 65, before it became Berlin Brigade.  Of course we had a few R-390A's in the station, USM620K, on top of Teufelsberg.  We also had some WJ receivers that went on up into the VHF range, don't know the model.  There were several 390A's used for the RTTY unit.  I think most of the R-390A's were used in the ditty bop stations located in other places around Germany, Turkey, etc.  Like Roger says, the receivers were probably procured by some bureaucrat at the request of the CO of the local stations or perhaps even back at Ft. Meade.  There was nothing special about any of them and I don't doubt that they got switched around all over the place when needed.  We also listened to a 64 channel PPM station on microwave.  We used about 24 old Revox reel to reel recorders for the channels.  I wonder if those old Revox recorders would be exotic because they were in a SOU?
