K2/100 Oscillation Problem

[william stewart-3]

I have an older K2/100, but it has all the mods that I know of and it
has served me well for about the past six months that I have owned it.
Recently, I noticed on the station monitor scope that there is a
"ragged" appearance to the waveform, on one side only, as I send CW at
100 watts, and as it warms up a bit. It is worse if it is being fed to
an antenna, but it happens even when fed to a dummy load. Any advice
would be appreciated.

Thanks,

Bill K5EMI

Bill,

Please be more descriptive about the "ragged" appearance.  And yes,
please confine it to what happens when operating into a dummy load.
