GB7DC Repeater

 

Welcome to the GB7DC Multi Mode DMR, D-Star ircDDB & System Fusion Repeater Webpage. The repeater went live on the air on the 27th December 2012 after a 3 year wait for the licence application to be approved. This was because 70cm is a shared band and we have to get approval from the primary user.

In March 2016 the repeater became Multi Mode and now provides DMR, DStar & System Fusion capabilities all from the same repeater. The System Fusion is still very experimental & currently doesn't support any networking features.

The repeater has a 30 Second Mode Hang Timer to reserve the current mode of operation. You might think the repeater isn't working because of this but actually it is just in one of the other three modes of operation only. After 30 seconds of no activity either locally or from the network will put the repeater back into Idle Standby ready for any mode.

If you require any DMR equipment to use on the repeater I can supply you the latest Motorola, Hytera & TYT Tytera DMR Radios via my company Mason Electronics.

I can offer very good prices to local radio amateurs, users of GB7DC & can also offer advice on DMR radios & configuration for use on the local repeaters.

Please contact me directly with your enquiry & I will do my best to help you out but not in working hours unfortunalty.
