[Elecraft] frequency creep on cw

[Mark n2qt]

still learning my way around the KX3 but figure this will bite someone else.

I have the KX3 set up for keying from N1MM logger in preparation for CQWW.
In chasing PT0S on 15cw I notice my receive frequency went down every time
I called (which running 5w and a big pile up I did a lot).  Went to MENU and
found the MIC BTN was on but not able to change since I was in CW mode.
Changed to SSB, put MIC BTN off and all was stable.
