ARC 5 Command Receivers

A brief video with some details about this US series of WW2 receivers as used by the US Navy and Air Forces, plus a few clips of two variants working the short wave bands. (Also a quick demo. of a period dynamotor!)

Thank YOU Clare!

ARC-5 types were used by the US Navy only. The BC types were used by the US Army Airforce. The USAF was formed only after WW2.

Apologies for the errors. I've updated my own records for this.

The LF version of the Command Receiver could be used to improve the selectivity of cheap receivers. Briefly, you connected them in to the i.f., then tuned them to the main receiver's i.f. that would typically be around 450 - 470kHz. This was known as a "Q-Fiver".

Most interesting. I hadn't heard of that being done before. These receivers were very popular here in the UK after the war and there still seem to be a lot of them around today. I've always been impressed with the high quality of construction from the US with their equipment, plus the superb maintenance manuals - IF you can find one!

@@lishaton Sadly, I've never owned an American receiver of that era: I was always jealous of my friend's National HRO (so much better than my clapped out British R107 and PCR). Most US sets were masterpieces of precision engineering, especially the tuning mechanisms. ♥
