Bob, My experience has been the same as yours. Extremely easy to do manually and stable.

I started on 160M and finished on 6M all in about an hour. Those values are still good some 1 year later. It is really nice to operate 160M - 6M at 500W (except 60M & 30M) and only change the frequency on my K3S. Nothing tedious about that.
