?I was having trouble with my ATU tuning on 15 M and above. It would attempt to tune, but the display would reset and the tuner would repeatably attempt to re-tune. Tuning on the lower bands was quick and steady.

I assumed that RF getting into the tuner electronics was the problem, so I added a single sided PC board to both the top and bottom of the tuner PC board. The fiberglass side of these boards was placed against the tuner electronics and the copper clad side was attached to ground. Sort of a "tuner sandwich". Problem solved.

The tuner now works on all bands without any problem.
