Having trouble with the squelch on my Pofung (Baofeng) UV-82. It's currently set at 2, but it doesn't seem to matter what setting I use, even all the way down to 0 I get the same results. On a VHF repeater, we don't have any in my immediate area so I'm not sure if it's a signal strength issue or what. I can key up a repeater and the radio will act like it's receiving, but I can't hear anything. The green receive light will come on, the display will light up and the active frequency arrow will blink, but I can't hear anything. If I press the "M" button to open up the squelch, I can hear what's going on. I have the frequency of my county's fire dispatch programmed into the radio, which is VHF (154 MHZ), I believe that it's all simplex too and I can hear every unit in the county that transmits, so the problem does not exist there. If I'm on VHF simplex with another radio and when I'm on a UHF repeater it does not have this problem. The radio obviously knows that its receiving so I don't understand why the squelch isn't opening especially when it's fine radio to radio on simplex and on UHF repeaters.
