Alinco: DR-MD520 Roaming Channels and Talk Groups

[qmsarge]

I have an Alinco DR-MD520 set. There are also a set of DMR Tier II repeaters located in various parts of the city which are linked with each other (i.e. Time Slot 2 of all these repeaters are connected and broadcast the same message/data). From the manual I understand that each of these repeater frequencies can be programmed as Roaming Channels, and then grouped under a single Roaming Zone. And either manually or automatically the radio can scan these frequencies and latch on to the one having strongest signals. The roaming channel or roaming zone did not have a provision to mention the Talk Group ID which should be listened into. If the Talk Group ID is not mentioned, how will the radio decide on which messages should be received?
NOTE: My understanding is that Roaming channels and roaming zones are for mobile operations, where based on the location of the vehicle the repeater strongest/closest to it would change and the radio should automatically change to the strongest repeater and then be ready for Tx and Rx on that repeater (but on which Talk Group? - that is where I am confused)

I also have a 520T but am using RT Systems software that makes programming a breeze. Further, they are very helpful with problems.

Thank you for your response. Will it be possible for you to check if RT Systems software allows programming Roaming channels, Zones with a Talk Group? At least check if the software provides an option to enter a Talk Group ID?

I know the software for my Anytone 878 allows for the entry of those.

The OP's question is specific to the programming of his radio. I think the thread is fine where it is.

I pulled up the RT software and noted they do have roaming channels and roaming zones. I'm not using this feature. So I suppose you can scan DMR zones as to wither you can tie this to groups is above my pay grade. Why don't you call RT Systems directly? They have always been helpful to me
