I am a new scanner in my area. About 6 years ago, I received a Uniden Bearcat scanner from my grandfather. I used it in New York. Then I moved to South Carolina, and it was in a box. I recently came across it and decided to break it out and see what I could find. I have found a couple of channels that come in real well. The ones on the 800 system. Now, to my question. I am trying to input the P25 channels and I keep getting an error message. How do I input these channels? If this is not the correct forum for this question I apologize and please, tell where I should post this. I am looking for North Charleston Police Department, and Summerville frequencies. Any help would be really appreciated.
