TYPE 6F TRANSMITTER

DATE OF DESIGN 1930
FREQUENCY RANGE 100 - 900 kc/s
POWER SUPPLY from transmitter types 37, 38 or 49
TYPE OF SET SPARK
WAVEFORM -
METHOD OF PRODUCING OSCILLATIONS n/a
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.

SMALL SCHEMATIC -
No photographs to show you. However, 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! Sorry, no photographs, diagrams or schematics!
