alphanumeric

Does anyone know if the Baofeng DMRs (DM-1701, DM-1702, DM-1801, DM-X) allow alphanumeric tagging of the channels (or whatever the equivalent is called in the DMR world)? Some ancillary questions: Besides the ones I listed above, are there any other Baofeng DMRs? Which Baofeng DMR seems to be...

Can anyone share experiences with Alpha tags and the GT-3? As far as I can tell only the RT Systems software supports alpha tags. Maybe I just need to spring for their software AND cable. Any feedback would be appreciated. Charlie
