I have the TX WARN system programmed into my PSR-500 but the only Colorado County talkgroups I seem to hear are the SO Dispatch and EMS Dispatch. I have never heard the PD or Fire talkgroups. Are these maybe TDMA? If so can anyone provide the TDMA slots I need to make a program for the BCD436HP that I have on order? I don't think they are encrypted because the PSR500 does not mute encrypted talkgroups.
