Sounds like the behavior the rotary encoder on my SDS100 is exhibiting. It gets worse as well, I've watched it become a slight annoyance, it jumps one selection etc. to jumping all over the place at the same two click positions. The rotary encoder is clearly failing after very little use.
Are you going to talk to Uniden about this?
I'm outside the warranty period but this should not be happening on their top of the line handheld scanner.
As we've discussed before my symptoms are identical, it actually seemed to start just as I was outside of the warranty, somehow or other I think this club will get bigger and bigger.
I remember when the battery clips started breaking and it was only a few people who were admonished for causing the problem themselves and that it was isolated and only affected a few units and wasn't enough for anyone to do anything about it.
Look at that thread now.
This Thread will be the same. I don't remember but I think someone said that same thing here. Something like it's an isolated problem and not significant enough to be addressed.
Let's see what this thread looks like in 6 months LOL.
