[Milsurplus] Where was RAL & RAK used?

[Edward J White]

Ni Gang:
Most of the SRR-11,12,13 that I saw were in Navel Reserve stations. While at 
Phila. Naval Yard looking for communications equipment on board ships 1970's 
to 1980's For the Navy MARS program We found the SRR's in storage they were 
used and I was told they were used for a short time between the RB* and the 
R-390A. Of course the FRR-59 were also used but were a night mare to keep 
running. But from what I was told the RB* were replaced by the R-390's than 
came The R-1051's.
