Collins 75A-4 - Demo of Receiver on 40M Band

Following cleaning of switches and pots, and replacing all paper,, all electrolytic, some disc ceramic and some silver mica capacitors, this video shows the receiver operating on the 40M range (coverage from 6.8MHz to 7.8MHz), receiving CW, LSB ham and AM broadcast stations). All controls seem to be functioning as intended and the dial accuracy is good.

@@user-bo8eq7ki5w I am in a very electrically noisy location. The antenna in use here is just a small indoor active loop, but that also picks up electrical noise. Other types of antenna are much worse.

I know what it is, "reception for radio tubes")). in the 90s I had a tube unit (Transceiver) and what (impression (!) I received it when distant American radio stations passed through the "polar cap" with CRYSTAL reverberation....
