I had an identical problem a few years ago with an SGC-239 autotuner that I originally used to tune my attic loop at the feedpoint. It was worst on 10 metres. It was suggested to me that RF could be getting in to the tuner. I thought that was a bad joke, because an ATU ought to be pretty immune to RF, especially if it is capable of being used at the antenna feedpoint.
I thought about this when I ordered the T1. I seem to recall Wayne saying that one reason the T1 doesn't automatically retune if it senses a mismatch is because this can sometimes cause problems. Because of my experience with the SGC-239, this seemed like a definite advantage to me. SGC sent me a new controller for the 239 that greatly reduced the incidence of this trouble, presumably by reducing the threshold at which it did a re-tune. I'm guessing that if there is an issue with the KX1, Elecraft could resolve it with a firmware change too, by making it work more like the T1 and only retuning if you change band or specifically tell it to.

It's just a guess, but in the past I've had similar problems with other rigs when this was the case, a voltage node at the rig... _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
