Is it selecting a particular sideband?


No. But actually there is no need for that -IMHO-.
Tuning to zerobeat in SSB is easy and rock stable.
Switching to SSB is easily done without shifting. And with some
additional IF-filters you can switch to the bandwidth working best in
conjunktion with bandpass shift.

Volker:
Yes but in true AM ECSS mode (syncronous demodulation), the zero beating is
automatic and tracks. You don't have to keep adjusting. Drift doesn't
matter, music comes in perfectly, it's locked! That is superior to any
manual ECSS mode.
