|DATE OF DESIGN||1929. Virtually the same as the 5C with a couple of subtle differences.|
|FREQUENCY RANGE||6250 - 25000 k/cs on some sets locally converted down to 4290 kc/s|
|POWER SUPPLY||1.5 kW Rotary Converter|
|TYPE OF SET||VALVE|
|WAVEFORM||ICW. The frequency of the note is very gruff owing to the low frequency of the A.C. supply from the rotary converter to the transformer i.e., about 70 cycles per second.|
|METHOD OF PRODUCING OSCILLATIONS||SELF|
|WHERE USED/FITTED||HF Attachment fitted with Type 2 or Type 4 from which the power supply is obtained. By this time, these two Type Systems were anywhere between 15 and 20 years old. That is no problem! As I write this the RN still have Type 42 destroyers fitted with ICS2 and that is 33 years old to my certain knowledge!|
The circuits show the series and parallel connection of switch 9 above. The picture on top shows the 5C when fitted with the Type 4 [destroyers etc] and the bottom with Type 2 all other ships larger than destroyers.
