WHERE USED/FITTED |
|
Deployed and fitted to Types 37, 38 and 49. The primary use of the transmitter is:-
(a) To dry out the deck insulator if weather conditions are such that the Valve set will not oscillate.
(b) As a stand-by transmitter in the event of a complete breakdown of the Valves or essential components of the Valve set. Uses quenched spark gap system. |

NOTES. |
|
This transmitter was known as the "RAD" or "Radiator", not that it merely radiated.....what Spark transmitter didn't ?, causing interference around the Fleet, but that its heat output was such to dry out any deck insulator, waterlogged or snow/ice bound, acting as a good heat-giving radiator! |
