Paul,
In the CW mode, the sidetone oscillator Phase/ Frequency modulates to some
degree the BFO, thus the sidebands appear around the carrier. I mention
this only for "information purposes" as I doubt that the raspy sound you are
getting is related to this problem. From my K2/100 the sidebands are some
80db below carrier (measured on 40m). The sidetone signal gets into the BFO
varicap circuit at U8 on the Control Board in my K2/100.
If Ron's suggestion does not solve the problem, can you listen to the BFO
and VFO signals?
73,

Geoff,
I did try this but it didn't solve it.
What I have found is that I was wrong in believing the CW was OK - its
not - it has a very raspy signal to it. So I will try to track that down
first.
I am confused about the behaviour of U2 on the SSB board - it seems to
take a long time to ramp up if it is setting the PWR level. However,
before I worry much more about this one, I'll try and track down my raspy
CW signal first.
