My V1 80-20m QMX has had issues with a glitchy VFO encoder. It would often skip in the opposite direction to which it was being turned which made tuning a bit awkward and menu selection even more so.
?
After taking the encoder out, dismantling it and cleaning the contacts, the issue was much better but still not great. I tried replacing the encoder with an AliExpress part that was linked in another thread but the A/B switch contacts were reversed on that one, requiring short jumpers to be run from the two outside encoder pins to the pads on the opposite side. Even then, those encoders were a bit pants (I tried a couple).
?
On a hunch, I re-fitted the original encoder and soldered a 10nF SM capacitor from each of the two outer pins to the common ground pin. This has now completely cured the glitches and the encoder works smoothly and accurately. I can now tune accurately and step through menus in the order they're meant to appear. Happy Days ??

I've attached a photo of the? bodge in case anyone else is having similar issues and wants to give it a try. If the photo doesn't appear, here's a link:
