OK Thanks for the Info.

When the unwanted sideband is cancelled by the circuitry how do you get
the 6khz bandwidth instead of 3khz.Or maybe you don't ????

I am talking/asking about the Drake R8A vs R8B receivers only... with
the bandwidth set to 6khz & AM SYNC mode.

Learning all the time.

With PBT, the ability to attenuate the unwanted sideband is limited by the
skirt selectivity characteristics of the filter.

With selectable sideband sync detectors, the unwanted sideband is cancelled
by the circuitry. This can be significant if the detector is well tuned.

The two are not the same.
