GB7KH, Kelvedon Hatch Multi-Mode Digital Voice repeater, is located at the Kelvedon Hatch Secret Nuclear Bunker, approximately 30 kilometres north-east from central London, where we also run the special event station GB0SNB.
The repeater was licensed early February 2015 and went live on the 6 April 2015 as an Icom G2 box. The repeater was later upgraded (September 2016) to an MMDVM based multi-mode repeater.

(21 Sept 2016) On the lookout for Motorola PMRs? The repeater needs two of the same model, ideally. Looking for any of the following: GM300, GM340, GM360, GM380, GM900.
(20 Sept 2016) After a few days of initial use, we have identified some small problems with the new repeater. These were to be expected, since running a repeater on a bench is different to having it on site. Work is scheduled to inspect and (hopefully) fix these. It’s a learning curve.
(18 Sept 2016) GB7KH is upgraded to an MMDVM based multi-mode repeater. Info on the changes is available here.
