For your information, DMR-MARC HQ advised the guidelines on Calling Channels in March 2015 -
The changes made at the end of January did in fact go through the repeater keepers just days before it was made known to the users. Again mention was made of TG235 in the notes which obviously were not read by users so to quote from the first draft of the proposal that was published "Because there is no easy (and easy to understand) way to have a contact with broader territories when required we see that TG235 is used. It is considered that providing the ability to connect a single repeater to any of the regional TGs on a User Activated basis, coupled with the provision of two “UK Wide” User Activated TGs will reduce the unnecessary utilisation of repeaters when such contacts are desired". It's only the changes that were aborted at the start of this month that were decided by the network admin
As for the TG1 issue - I wouldn't say it's an issue limited to users in the UK alone - the Americans are fond of TG1 & TG13 to chat to others in the US. Plus when someone dos try to guide those people, they get abuse and branded the "DMR Police" - a situation that happened this past week.
As for SE politics, could this be due to the fact that when the UK setup it's own c-Bridge, this was initiated by repeater keepers in the SE? I personally do not know why there is a north / south divide - it may have started before I got into DMR. Yes, the c-bridge is in Greater London, Yes, the c-Bridge has it's administrators in the SE region - does it really matter what part of the UK they are from? If one does want to point fingers at regions, then they should be told that the network infrastructure was setup and maintained by a northerner who resides in Lincolnshire.
- not only did they affected TG1, TG2 and TG13 but in theory any wide area talk group thus TG235 is included. It's being pushed more so now as TG235 now has UA talk groups to supplement it as the WW TG's got TG's 113, 123, 119 & 129.
