In ProScan, Add System. Select DMR One Freq Trunk. Add Site (Frequencies). Add Channel (Frequency). Enter Frequency and Color Code. Add Group (TGID's). Add Channel (TGID). Enter TGID Name, TGID, and TDMA Slot. When you scan the system, I suggest that you put the system into ID Search. You may find a sheriff tac talkgroup using the same frequency with a different TGID. Each TDMA frequency has 2 audio channels (slots). You can have 2 simultaneous transmissions on a single frequency.
