Bot sure if it's a bug or if someone is barley breaking the squelch

While scanning, the backlight stays on unless you program the backlight to be off for waiting, in which case you can't see the screen in the dark unless you either transmit or break the squelch with the MONI

Ofen times one is able to break squelch but their signal is lost in the background static, which is indicative of a low power signal.

You can program your radio, save an image of all the settings each time you make changes, clone the info to other radios (with same firmware), change squelch sensitivity to the static squelch menu settings
