Dial-a-repeater !

Direct Dial – as it’s known, is available on GB7MB – but what is it ? well, it’s good news from the Guys who run the kindly run the British c-Bridge over at and good news for British DMR-MARC Repeater users in general.
Quite simply, it allows you to direct your call to a specific DMR repeater – rather than ‘lighting up’ all the other repeaters inbetween, As you know, we have two timeslots (channels) on a DMR repeater, and so, careful selection of talkgroups must be chosen in order to make best possible use of both repeater channels (slots) ..  leaving a slot on the repeater available to locals at all times, while at the same time providing non-local connections. Being able to chat to your friend on another DMR-MARC connected repeater (without tying up any other repeaters) is a sure win for DMR-MARC users in the UK.
The talkgroup times out after 5 minutes, so does not constantly relay unwanted traffic to your home repeater.

This ability is enabledand you can now add these new talkgroups to your codeplug now.
GB7MB is TG 915
