Hi Johhny,

Symptom suggest the oscillator is running too slow. You may have inadvertently aligned on the 2nd harmonic of the oscillator. See if loosening the trimmer adjustment 7 is possible to get the oscillator frequency running faster. With a station at 1200, the oscillator should run at 1670 kHz in the case of your radio having an IF frequency of 470 kHz. Your padder adjustment 9 may need loosening up too if it was tightened down as well.
