Communications equipment pictured here include a URC-32 HF SSB transmitter in the rack at right. An R-1051 HF SSB receiver is mounted on a shelf with a pair of URA-17 FSK TTY converters above it. Just to the left of them there is a TTY patch panel and what looks like a crypto switch box. Mounted on the left side of the model 28 Teletype is probably a KWV-7 remote control box for a KW-7 TTY crypto device, not pictured. Just visible on the left is the receiver of the AN/BRN-3 Satellite Navigation set.  Far right, the CalComp plotter buffer.   [Admin]
