1974 list of equipment in use at selected receiver sites
Data from Jan 1976 manpower survey document -
I have merged and omitted some model numbers where it made sense
The primary HF rcvrs were the AN/FRR-60 and R-1051/URR
(with a few older R-390 and FRR-59 rcvrs still around)
A few WRR-3 and BRR-3 LF/VLF rcvrs were in use
The URA-17 was the main RTTY converter
