I am currently using a Baofeng BF-F9V2+ radio. I have found that when listening, my squelch won't stay open, despite getting a good clean signal. I am using a homemade vertical dipole antenna for 2-meter band. Compared to the rubber duck, it gets excellent reception signal, except for this unreliable squelch problem.
I have also found that when I turn the squelch off, I get a continuous signal, so I do not believe that it is a problem with my antenna.
Are there variables that could cause something like this other than an issue with the radio?
