Recently programmed the Maine State Police in my area on my Uniden BCT15x Sometimes it’s clear and I hear every word when they talk over the radio, and then other times there is static, when I have 5 full bars of connection. One cop will come in fine, while another has a ton of static. Other local police departments come in fine with no static at all. Am I a frequency off? Does it have to do with my distance from the tower? (50 min away)
