Like some others have reported, I often tapped the DUAL PB button instead of holding it, thereby selecting the SSB filter instead of engaging the APF...
To avoid this, I chose to assign the APF to setup "II" of the HICUT/WIDTH button, so an unintentional "tap" would only switch between HICUT and WIDTH... which is not so annoying.
Then changing CONFIG:DUAL PB to NOR again, setup "II" kept the APF and now, switching between "I" and "II", I can choose between APF and DUAL PB without going through the CONFIG procedure. I find this very convenient indeed.
