Create a channel with the correct CC, TS and TG for each repeater you will be traveling between. Make sure IP Connect is checked. This will only work with “real” DMR Repeaters which has IP Connect like a Motorola XPR or SLR series or Hytera RD series. It will not work with hotspots and most home-brew repeaters.
Create a ROAMing list.
Add the channel in the same way as a scan list, however as a TG specific roam list. Name the roam list the TG, E.G.: TG3100.
As you move and loose one repeater, the radio will switch to the next repeater in the roam list with adequate signal (usually better than -108db) while your main on the same talk group. Your radio will actually ping the repeater and log on (register).
