Problem: AUBSUK multiple scan list

The scan lists aren’t combining correctly on AUBSUK firmware. It’s skipping entries based on ordering. I realized I was missing most of simplex channels, but seeing the GMRS channels, when I enabled my “simplex” scan list in combo with primary repeaters. There’s an existing issue logged, but it’s hard to describe and to reproduce, I think.

Trying the Next Firmware, F4HWN 3.7

F4HWN is available on GitHub. I loaded it on both radios in place of AUBSUK to see how I get along. I’ve found a few features I really like:

• Scan on start: if it’s scanning when I switch it off, it’ll scanning when switched on.
• 3 scan lists: 1, 2, 3, 123, 0, all
  • they don’t recombine as freely, but I have:
    • simplex, repeaters, satellites on 1
    • GMRS on 3
• scan is just as fast as others, so we’ll see if it’s tolerable.
• “main only” display is nice, much easier to read.
• spectrum analyzer with scan range, but I can’t assign it to a button.
  • Fn-5 is only way to activate it.

I think the S-meter is calibrated much differently from AUBSUK, and other firmwares I’ve loaded, calibration for VHF/UHF vs HF, The S-meter seems to read higher than I expect with lots of S9+.

The spectrum analyzer with a range seems wonky at times: it may be scanning the entire range, but the graph doesn’t seem all there. I noticed it with the scan of 144MHz-148MHz.

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.
