The main HF/MF receiver in the Fleet during the pre and actual COMIST period dating from the late 1950's until the mid 1960's. It was synthesised and thus very stable, but compared with the receivers which replaced it, it was a complicated set up having many inter-related parts.

Fitted widely throughout  the Fleet.
