Default What is Passband Tuning?

Hello,

I read in a post the new Eton has passband tuning, what does that mean?

Thanks,

Neil

Passband Tuning and IF Shift


These two similar techniques allow the operator to manipulate a receiver's
filtering circuitry to favor one of two close-spaced signals without simply
narrowing the passband, which would produce muffling of the audio. Instead,
by shifting the passband, the unwanted signal is rejected and the desired
signal's bandwidth is preserved.

Nice pictorial shows twin passband tuning but single passband tuning is
similar

Also see page 36 of the Kenwood TS-570D Manual at URL:

Another nice pictorial of the IF Shift control
