Welcome and thank you for checking in with us here at the home of North East Lincolnshire digital repeaters.
I'm Carl G7EOG and I'm the repeater keeper of GB7GC and GB7WA.
I may be the repeater keeper of GB7GC and GB7WA but it's not possible without the help the of members of Grimsby Amateur Radio Society and Bertie 2E0VBM for the use of a bedroom corner and a much needed electricity supply and my long suffering wife for the use of parts of the garden and roof.
Both repeaters are duel mode digital repeaters supporting the DMR (Digital Mobile Radio) and D-STAR (Digital Smart Technology for Amateur Radio) modes.
The repeaters can only operate in one mode at a time, for example, its first come first served so if somebody has activated the repeater in D-STAR mode it will remain in that mode whilst it is receiving a valid transmission either into the repeater locally or out of the repeater via the internet and will hang in that mode for 20 seconds after the last D-STAR reception or transmission, the same stands for the DMR mode.
To activate a particular mode just requires a transmission, in that mode, into the repeater via RF locally or via the internet.
DMR wise the repeaters are connected to the Brandmeister network, the repeaters have 2 time slots that operate simultaneously, it basically splits the transmission into two time periods or "Slots", these two slots allow two separate conversations to use the repeater at the same time. On GB7GC and GB7WA time slot one is reserved for local traffic and is permanently connected to talk group 1472 (the local telephone dialling code is 01472) time slot two is free to allow users to connect to any listed talk groups that are available on the Brandmeister network. Because both repeaters are always connected to talk group 1472, it does mean that if someone accesses the talk group the repeater will then operate in DMR mode until there is at least a 20 second gap, at this point it would be possible to switch the repeater into D-STAR mode.
D-STAR wise a user can access any reflector available and, as stated above, once in this mode it will remain in this mode until there is at least a 20 second gap in transmission or reception of a D-STAR signal.
Finally, if you want to check if and what mode the repeater may be currently operating in just click on the relevent link above to go to the live dashboard where you'll also be able to check recent activity.
Ok, I hope this information will help you to enjoy using either GB7GC or GB7WA, this page is not meant to be an in depth introduction to either of the modes mentioned, there are far better sources of information else wear on the web. So now when you think that the repeater has something against you or that your radio is just not working, maybe now you might stop and consider that perhaps the repeater may be being used in another mode to the one you are using, if so go and check the live dashboard and it may save you a lot of frustration. Hope to catch you on the air sometime, best 73.
