Hi All,
This is my first post here so bare with me!
I have a Zenith 5G405 that I'm nearly done restoring and have started tuning it up. I adjust the trimmer on the tuning capacitor and it only reduces the signal as I turn it in (tighten). There should be a sweet spot where turning one way or the other reduces the signal, correct?
I decided to check the resonat frequency of the RF stage and it is off relative to the local oscillator. For instance, when I tune the radio to 1500 kHz received signal the front end RF tuning resonates at 1200 kHz. Shouldn't the RF stage track the local oscilator?
BTW, the antenna coil and the tuning capacitor forms the front end stage.
Thanks,
John
