GB7WI is connected to BrandMeister network providing reliable digital communications to radio amateurs worldwide. The repeater keeper is Kevin G0UZJ.

Having two Time Slots (TS) allows two conversations to take place simultaneously using one frequency. This means you can be talking to someone on TS1 on a Worldwide/USA/Europe/UK Talk-Group (TG) whilst another station uses TS2 to contact someone local or connect to a reflector. There are currently over 90 reflectors.

A huge advantage of BrandMeister is that it is dedicated to amateur radio, you can use Motorola and Hytera repeaters, GPS/GPRS, Reflectors and you can use a DMR hotspot/dongle/accesspoint and homebrew DMR repeaters! No matter where you are in the world, if a repeater is available or not, whether you are in your car, house or in a hotel room you will have the capability for worldwide communication.

Where TS1 implements TGs similar to DMR MARC TS2 implements the use of reflectors similar to the DSTAR network. The easiest way to use the reflector is to program your radio with TG9 (local) in TS2. This is the only TG you will need for a QSO on the reflector.

To link and unlink a reflector, program the radio with the reflector number as a group call on TS2. To link to a reflector, select the reflector number from the contacts list and transmit for about 1 second. The repeater should respond with a voice announcement, "Connect to reflector xxxx". Then go back to TG9 to make a QSO. To unlink select 4000 from the contacts list, transmit for about 1 second, and you should hear a voice announcement "Reflector Disconnected".

To enquire about the reflector link status call 5000, and the repeater will respond with the currently linked reflector.
TG9 will default to the UK reflector 4400 after 5 minutes on inactivity.

GB7WI is a digital radio amatuer repeater located in Winterton, N.Lincs, England. Using a Motorola DR3000 we are able to provide 2 digital time division streams (technically known as a Time Slots) providing worldwide communication on the same frequency.
