RCA 811k expert advice needed
#5

Do try a good aerial/antenna first. This will help, as the efficiency of short antennas is very much compromised on broadcast band, and this gets worse as you go towards the 520 kHz end.

Does your set have a loop antenna/wave magnet in the console, or just the connection for a wire?


Caps can cause trouble. On my 110K, I did had to track down a bad mica cap in the RF section for one of the shortwave bands. I could not get the required adjustment with the trimmer during alignment. This band was created with several fixed caps, leaving the main tuning cap only making very small changes to the overall combined capacitance. Drift in the fixed caps did not have to be much to cause a big effect. That shouldn't be such a problem on the regular "broadcast" band.

I don't hold with furniture that talks.
