Developed a Spectrum Scan / Signal Survey feature!

[Hamberthm]

Hi to all!

Just added this feature I really wanted to develop before getting my radio. If @max-arnold likes it, I'll gladly do the PR!

It does a tunning sweep & RSSI scan on the visible scale a couple of seconds after touching the encoder. It records the RSSI values on memory, so they persist as the screen gets redrawn.

[EmEiBee]

Hmm, that's cool.
But only the visible scale? What's the downside to running it across the entire band? Does that take too long?

[Hamberthm]

Yes, it would turn uncomfortable, at least for me. You can estimate the time by viewing/listening the video, imagine twice that for a 2-screen long band, and so on. The audio mutes as it scans.

[Hamberthm]

Thinking it again, I will try it later, it may be better!

[EmEiBee]

...presumably depends on the user and how they use the radio.
Perhaps you can make this optional and set in the setup menu whether you want to scan only the current band section or the entire band (or not at all), i.e., the options "OFF / Visible / Full"

[Hamberthm]

Yes, I'll do the menu options and release it to my branch!

@Hamberthm Please do a PR but do not spend too much time on polishing it, just dump the code as is. Marat and Sergey already done a working Scan feature (see the "scan" branch), so I just want to take a look at your implementation

[Hamberthm]

Hi @EmEiBee and anyone who wants to try this feature, I rewrote the feature to be in line with the recently merged Scan branch on this repository.

The new official Scan feature is invoked from main menu and does a high precision, but slow all-band scan.

I moved my implementation to the Settings submenu under the name "Fast Autoscan". It behaves like the video on the first post but using the official Scan code.

If you want to try it, I published a release with the binaries. I will also be maintaining my branch on this feature to keep it in line with the official project.

Cheers!
Humberto

Great!
I will try it tomorrow; too much Irish whiskey level at the moment ;)

Hi! Here's my implementation of a "Seamless Scan"

• Scans as tunning happens
• Holds a std::Map with the RSSI values of the freqs on screen
• Map is only as big as screen (size configurable via definition)
• Shows bars as relative RSSI and it calculates min/max just as standard Scan
• Doesn't scan while band changes to avoid lagging the menu selection

Diff: main...Hamberthm:ats-mini:feature-seamlessAutoscan

Demo: https://youtube.com/shorts/vKSQxVgamlk

I kept the first commit as clean, compact and compatible with the upstream as possible, so it is ready if @max-arnold considers to merge it. Only needs menu configuration.

I'll be making it configurable and merging it onto my autoscan branch today on the afternoon.

Cheers!

Humberto
