Your comments:

• These receivers were the main stay of HF comms on Christmas island during Operation Grapple Z (H-bomb tests) in the late 1950's The slightly different grey coloured box (Centre right) was another receiver used as a "Guard" channel which would be preset to a frequency and any received signal would be heard along with the main signal.They were also used at the Maralinga Range in Australia......
