2015, May 14th 2015, On Acension-day\u00a0\u00a0I,ve managed to buy a couple of BC453 receivers. It was at a car boot sale during the \u201cJutberg event\u201d, a radio Flea Market, where I found a BC453-B from the Royal Canadian Air Force and \u00a0a ARC (Aircraft radio Corporation) R-11-A receiver. Both receivers where offered to me for a 30\u20ac both, which I accepted. The BC453 was one of a set of similar receivers covering different frequency bands for airborne use and known as the \u201cCommand Receivers\u201d. The BC453 coveres 150 –\u00a0560Khz, so Long Wave Band<\/p>\n

This saturday-morning, May 23rd, 2015, it was raining and I decided to do the smoke-test on both receivers.<\/p>\n

The BC453 was modified to 12V filament. As my tube power supply was 6,3V, I decided to use an industrial switched powersupply for the filament, in combination with my homebrew EZ80 tube powersupply. I used my variac and after warming-up I applied 150V to the reciever, which resulted in a humming end crackling audio. I started turning the receicver-dial and noticed that this old baby was still working! First station logged was a beacon QPR on 374KHz, located North sea on 9:24 UTC.<\/p>\n
