GE 50 Clock Radio
#6

All of my voltages are good and the radio plays - one station. I took a modulated 1620 kHz radio signal and applied it through the antenna through a 100pF capacitor. The ground was connected to the common through a 0.1 uF capacitor. After turning the station selector as far clockwise as possible I adjusted the RF and RF trimmers to get maximum volume. After changing the radios signal to 580 kHz I could tune in the signal by turning the selectors almost as far counter clockwise as possible. If I go too far, the radios growls.

I can only pickup one station at two frequencies and I'm not sure why. This seems very odd but I did have to restring the coils. Unless that needs to be very precise (and yes it is a pain in the backside to do) I'm at a loss now. I tried to check the capacitance of the mica caps by the meter I have reads them very high, even new ones that I have bought. I've never had much success measuring capacitance of a wired part. The radio is not very valuable but I would like it to operate well enough to reassemble it and the clock and have both work just to do it. Any one have any suggestions?
