[Elecraft] K3 unable to change passband control shift amount in SSB

Setting to “NOR” by a long press on Shift control should reset the passband, if having it off center is what’s causing your issue.

Full disclosure, I don’t use SHIFT/WIDTH on SSB, so switching between the two modes is not something I’ve done since building the radio in 2008 :-)
