[Elecraft] K2/100 Oscillation Problem

[William Stewart]

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,
