I have a question regarding the CTCSS function on my home patrol. I cannot seem to get that function to work on my radio. I have many frequencies for my area programmed, but when the scanner stops on any those frequencies, the CTCSS codes do not show up in the display. And I am also getting splash over from frequencies that are close together 156.000 & 156.2175. I have all frequencies programmed through SENTINEL, with the correct pl's, but the radio doesn't seem to recognize them. I have had the radio for a few years and I believe the CTCSS function worked before. Maybe I changed something by mistake??
