RECEIVERS

CDC/CDL/B28

NOTES

The B28 was for many years, throughout WW2 and afterwards, the main Fleet MF/HF Receiver. Outwardly, its switches and controls were simple and uncluttered when compared with the B29, and it was a superhet receiver, as opposed to the TRF (Tuned Radio Frequency) of the B29. In most cases, a ship would have several B28's fitted to just the odd B29. Note the three out of four names this receiver was called throughout the years. In the first of three pictures there is a reference to the "CR100", the manufacturers name and also to "Tuner-Amplifier B28" its name when first entering service with the Navy: the Type 65 is fully covered in the Transmitter Matrix. The second picture refers to it as being a "CDC" which is its official sea-going name whilst the third picture simply repeats its original Naval title. Its fourth title was "CDL" which it assumed when fitted ashore in Naval W/T Stations.
