Hello All, I was running on the CP210x 5/7/2018 ver.10.1.2 driver on my win 11 22H2 pc and SatPC32 ver 12.18 to my IC-9700 and everything was working fine. Then Windows update offered an update for CP210x to ver 11.2.0 and once installed the IC-9700 would no longer switch bands reliably nor set frequencies correctly all the time.

Switching back to the old driver fixed everything.

So just a FYI YMMV.
