I believe Phil is referring to the pitch of received signals over ~S9. 
Here's his original post and thread from over a month ago:

The pitch change is very subtle (<1 Hz change) and seems to occur mainly on
strong received signals.  Rather than being a transmit artifact of the
external signal, it seems to be something inside the K3...noticeable only if
you can discern very slight frequency changes.  It's not annoying to me but
more of a curiosity as to what may be causing it.
