Default Re: ECF82 frequency changer

Even with a 465kHz IF at 30MHz, 1MHz difference between the wanted and image signals would allow a roughly calibrated separate RF tune to pick the right signal.


The idea would be more attractive for a homebrewed receiver where getting the RF/Oscillator tracking right would be more problematic than the slight operational difficulty of separate controls.
