....and what does it sound like?
I used to think it was a type of radio but since reading this group
I see it is a sound.

Thanks,

Basically, it's when your radio receives radio waves they travel through
the tuned circuits of the RF deck or front end and depending how you have
the dial set a specific frequency will emerge and travel into the mixer
section of your radio and combine with the locally generated frequency to
produce a new frequency that is more stable and it is equal to the sum or
difference of the two. Simply to combine two frequencies to create a new
frequency. The superhetrodyne is the basis for all modern receiver
designs and uses this technique.


Out of the mixer (sometimes referred to as the converter or 1st detector)
will be four frequencies. The fundemental frequency the set is tuned to,
the local oscillator frequency, and the sum and difference of the two.

True but we were trying to keep it simple.
