If recording and the squelch level is set, the recording will not include the noise between transmissions. Good for monitoring infrequently used channels such as ham repeaters and fire department communications.
and remove commented out code
Pressing m or M reduces volume to 0.
Signal Bar shows signal strength. Changed squelch to operate on damped signal level. Quieter when set close to trigger level. Doesn't drop out on weak signals.
Shows signal strength bar graph.
fighting cache, I think

Yes, I forgot to make squelch work for recordings too (my previous try at squelch worked in a different way that muted the audio in the recording automatically). I'll make a few experiments to ensure that there's a bit of silence in between separate transmissions, because if it stops recording as soon as the audio is squelched, the resulting recording could be quite frenetic, with all those quick-witted, fast-talking cops and firefighters :) |

The latest version of my squelch uses a dampening calculation to prevent the quick on and off pulsing of the squelch. Real radios sometimes have time delays for when to shut the receiver off again. There are many ways to skin this cat :) |
Prelude to a preset scanning function.
Prelude to preset scanner.
Clicking on the signal strength bar graph now sets the squelch level. The signal strength can be displayed numerically by hovering the mouse over the signal strength bar graph.
1. Added squelch to the parameters saved with each preset station. 2. Changed default checkbox when importing presets to show "Delete these presets" with boxes prechecked. It was not intuitive before that it would not delete the current presets unless the box was manually checked. This use assumes that each file is a different set of presets most of the time. Not an overlay. 3. Display the squelch setting saved in the preset manager.
1. PgDn now selects the previous preset in the list. 2. f keyboard shortcut now works. (was in help but not working) NOTE: using PgUp or PgDn too quickly can cause multiple decoder instances. Looking for a good way to block this... For now, users should be careful.
A rudimentary test of preset scanning. Shift-PgDn will start a scan of the preset list. If the signal exceeds the squelch level, scanning will pause. Just a kludge for testing. But it seems to work, surprisingly.
Click on "Squelch:" to temporarily open squelch and monitor frequency. Preset scanning stops. Click again to resume preset squelch setting and continue scanning presets.

Useful for monitoring channels with infrequent transmissions such as ham repeaters or fire department communications.
If squelch is 0, no change.
Also set help screen to normal window instead of maximized. (A personal preference, I guess).
Added signal strength bar graph.
Changed squelch to operate of damped level for smoother operation.
Added keyboard shortcut m to mute volume.
