I updated today and made a minor mod to my HT, lowering default tx power on one of my stored freqs. That failed to store the mod on HT, no error msg. Tried twice. Failed.

Then back in the truck I found that I could no longer hear other HTs in our convoy. So I reset the HT, uninstalled the latest CHIRP build on my w10 box, went back to daily-20201014, re-uploaded file to HT, and all is working fine again.
