The tune settings on the upper electrode have shifted again from 19000 up to 23000 and 26000.  The limit is a bit above 30000 and we seem to be approaching this.  The load setting, however, remains the same.  I wonder if the coupling for the tune in the automatch has slipped -- and am shutting down so it can be checked.
