GB7DD – Dundee


Updated 21/09/2020

A proposal was submitted on 18th May 2020 by MM0DUN to resurrect GB7DD as a dual-digital-mode repeater running an MMDVM board to provide DMR on the Brandmeister Network connected by default on Slot 2 to DMR Scotland Talkgroup 2355 and NXDN connected by default to the NXDN Scotland Talkgroup 23551.

Now that the repeater is up and running it is anticipated that the repeater will give coverage from Arbroath (high ground) in the East, to the Eastern outskirts of Perth, South to St Andrews and Glenrothes and North to Glamis.  The prediction map below gives a very approximate idea of coverage, which, as always, may be slightly better or worse.  Dundee is a difficult area to cover due to the Law and Balgay Hills blocking the signal to the west.
