The rf generator for the coil appears to be overheating. The symptom is that the matching networking stops being able to get a reasonable match after 10 min or so into a run. You can see the problem if to trace the forward and reflected power during a run. For now the solution is to keep the max power at or below 2500W to set the coil generator to "forward" mode. On Monday, I will looking at the generator cooling to see if it is the cause of the problem.
