Squelch improvements
Posted: Tue Jan 24, 2023 5:08 pm
Here is a list of some things that I think might improve the squelch functionality and would be nice to see implemented eventually:
- Attack/decay settings for FM and AM squelch (I have an issue where the squelch sometimes randomly opens for a split second when there isn't even a trace of signal present, which is a bit annoying, and it happens even if I have squelch level set a few % above the "Auto" setting and have noise blanker enabled. Maybe this could be fixed by adjusting the attack setting / how fast it opens after it detects a signal. I wouldn't mind if it opened a bit too late, and if I was doing something where that would be a problem I could change the setting back. For AM squelch it would be nice to be able to change the decay setting, as it stays open a bit too long after the signal is gone);
- Higher maximum setting for FM squelch (currently it has to be near maximum when the noise level is at just -80 dBm);
- Global "Auto" button for setting the squelch value on all the currently working receivers that have squelch enabled;
- An ASQ feature that automatically adjusts the squelch level as the noise floor changes over time (maybe by just periodically doing what the "Auto" button does, but only if SNR is below a certain level so it doesn't do this when a signal is present);
- Use the same units for squelch level setting as the spectrum display scale;
- Display something (for example a horizontal line) representing the squelch level on the spectrum when the mouse cursor is on the squelch level slider.
