Hi, I just joined, and I have a question. I'm using a Pro-668, and I have finally started to figure out how to pick my local police channels. But I've noticed that even though I'm getting strong signals, it's usually difficult to hear what's being said when listening to Lake County police departments. But the ISP comes in very clear and according to the screen some ISP broadcasts are coming from many counties away. Any suggestions would be helpful. Please remember that I am new to the p25 system and digital scanners in general.
