[Elecraft] KX3 Auto Notch not working on SSB

[Dennis Dease]

On my KX3 when I'm in USB or LSB and long press NOTCH I get a N/A response.
When I am in AM and long press NOTCH i get an AUTO response (normal).
When in CW mode and long press NOTCH i get into manual notch mode (normal)

Wondering why in SSB I get N/A with a long press of NOTCH  ??

Thanks,
