If the counter shows that change, its the PTO. Likely a failure of voltage regulation. Which might be caused by dirty or loose connections on the power connector or something internal. I don't have my Corsair II manual handy to look up the circuit.

Tonight while enjoying a nice CW ragchew, the other OM told me that my
rig was changing frequency about 100 HZ when keyed.  I have never been
told this before, so I experimented a bit, and it looks like that
happens according to the display.  The counter shows an increase in
frequency when keyed of about that amount.  It seems to do it with both
the internal PTO and the external VFO.  I have checked, and the offset
is switched off.  Does anyone have an idea of what is happening here?
