Scanner of channels V2 #95

redradist · 2023-07-27T17:21:33Z

Depends on Auto Squelch for channels
Rebased version of Scanner of channels

krakenrf · 2023-08-03T01:15:52Z

Just noting I am planning on looking at these PRs soon, maybe next week though.

godsic · 2023-09-13T20:05:18Z

@redradist Lets make it happen!

redradist · 2023-09-15T06:12:34Z

@redradist Lets make it happen!

I will rebase it in few days

@redradist Lets make it happen!

Done

godsic · 2023-10-19T16:34:29Z

@redradist Could you please move all the scanning functionality into a separate file, i.e., outside _signal_processing/krakenSDR_signal_processor.py ? It would be a bit easier to review and maintain.

krakenrf · 2023-11-07T05:49:11Z

@redradist testing this now, but I'm not exactly sure how it works. It seems to put a red VFO box around some strong signals, and then randomly receive some of the weaker signals with a green active VFO box. But several some strong signals are always missed. What is the intended behavior when we have several always active channels in the bandwidth?

We probably also need a way to restrict the number of VFOs it creates for systems like the Pi4.

One part of the algorithm also must be quite slow, because it slows down the Pi4 quite a bit, even though only one signal is actively green.

@krakenrf Updated PR, now its behavior more consistent

Improved detection of the similar box. It should eliminate extra boxes inside of another big box
Renamed center_freq field to pick_freq field because it more describe what does it field mean

Got some conflicts after the last merges, can you please check?

Got some conflicts after the last merges, can you please check?

@krakenrf Lets merge #114 and then I will rebase this one

Refactor initial implementation to work correct with long sequence of transmition Hide option Active VFOs in case non Standard VFO Mode Add display of detected frequencies Changed print -> self.logger.debug Add fm demodulation and iq channel writting Add possibility to block channel for scanning if exceeded timeout Reset colected information for channel if channel was marked as blocked Refactoring after main rebase Added handling params for VFo Scan mode

… band_width from ScanFreq class, changed condition on check if it is the same frequency

krakenrf · 2024-02-13T05:35:41Z

@redradist testing now thanks.

Noticing a bit of an issue with the all the VFO cards not showing up sometimes. Only showing up after making a change to the VFO config box. Also sometimes some of the settings are not showing up for VFOs scan mode
I'm still confused how the scanner works, can you provide a short tutorial? What is the blocking time used for?
I still see it choosing odd channels, and sometimes all the VFO bars just dissapear.

Once when I changed frequency the whole web ui crashed with error in the logs:

For some frequencies it just seems to select the wrong bandwidth or be offset from the actual signal

Often after a few seconds it just stops selecting any channels at all

and the logs show
