WHERE USED/FITTED

In 1939, Type 74 was listed as being CONFIDENTIAL. There was just one set, the 74X, an experimental transmitter. It was a W/T set to do with W/T communications which were higher than normal (at that time) VHF frequencies and using voice (R/T) which had just been perfected by the Admiralty Signal Establishment. We do not hold any further information on the Type74 but we do know that it was fitted in the Aurora, Nelson, Renown and Rodney so it could have had something to do with big gun fire control/co-ordinations.
