Agreed. Actually, it just occurred to me that this could be RF getting into the works. I seem to remember that the only time I've seen anything like this was under a high swr situation where my tuner was having a difficult time finding a match - I put it down to too much stray RF getting in there and interfering with the control of the ATU, preventing it from doing its job - never proved this of course, and haven't seen that problem since. I wonder if attempting tuning with either a dummy load on the end and/or reduced power might provide useful information to help solve the problem. In any event, I see Eric is on the problem and has posted some suggestions.
