Thanks for the response. Yes it's consistently roughly 5 kHz below the designated frequency. For example if I want to tune in 11815 kHz I need to key in 11810 kHz to hear the signal (not perfect, still need tune up a bit with fine tuning dial) I don't know the exact amount of the frequency off as you may know the radio tuning is in a 5 kHz step.
So if IF alignment is the case I don't think I can handle the job. May need to find a technician to do the job...
