I loaded F4HWN 3.3 onto my UV-K5 to have a look. It only has 3 scan lists, and it’s awkward to cycle through them. I found starting the spectrum analyzer to be cumbersome as well, since i couldn’t attach it to a long-press of a button. The single VFO view is pretty nice; it puts lots of nice info on the screen, and it’s big. Ultimately, I went right back to AubsUK for the scan features.
