HS34 HDG Selector intermittent.

[Randyf]

The heading selector on my horizontal HS34 will only change if I make several aggressive spins on the selector knob. Even when it does change, it does so erratically and only after several attemps to change the heading. The heading SYC works properly and the autopilot will follow the heading commands. Perhaps a internal mechanism problem or dirt accumulation? Only other choice is to send it out to DYNON for service or replacement. Any help would be greatly appreciated.

I would tend to agree with your guess, but I don’t see how Dynon would be the only "other" choice. They're your only choice, unless you're planning to crack open the unit on your own. I wouldn't advise that.
