I have sdrtrunk set up with several VHF P25 channels using rtl-sds dongle, the channels in the same county using the same simulcast system. They are within the spectrum and have TGID programmed in them all. It will pick up 5 of them with no issues at all. I have 4 others programmed the same with the TGID and it will not receive any traffic at all. I am so confused on why. Any suggestions?
