Hi, Does anyone know What Double Super Hetrodyne does in a CB radio.
I have a GE 40 channel cb and it has Double Super Hetrodyne.

The straight answer? Double conversion is used to reduce images.


It does nothing for sensitivity or selectivity in itself; and it probably
decreases dynamic range and makes the receiver more prone
to spurious responses.
