    Default Linking two Trbo repeaters in digital mode via RF?

    Is this possible with out it sounding like crap? Reason I ask. One of the local clubs has two 8300's and they are looking into having them updated for dual mode. The primary use for these repeaters would be analog for races Comms and they are linked in analog mode to be able to talk to one side of the county to the other. It would be nice to do in digital mode it seems like it could be done but I'm not sure. I have very little knowledge when it comes to DMR.

    IPSC is a digital only function. A repeater running digital will link over Ethernet, but if provisioned for dual mode analog/digital operation if an analog signal is received, the link path will go down, and the link will need to be re-established. This can take some time, since the Ethernet port is not supported in analog mode.

    The primary purpose of dual mode repeater operation was for repeater sites where migration to digital was in progress, but the site was either difficult to access, or not all users would migrate to digital on the same time frame.

    And it cannot be done by RF.

    That's what I kinda figured. Chances are they will probably not use IPSC being that there is no Internet access at any of the sites.

    Are you wanting to just link the repeaters together on their own independent IPSC network, or are you wanting to join a regional or national network?

    To be fair, you could interconnect the two repeaters via RF... just not in-band. The repeaters would need to be digital-only (so IPSC will function) and you'd need to provide a wireless IP backhaul (2.4, 5.8, licensed 4.9 if you qualify, etc.)

    When we get everything and get it set up. We would like to link one of the repeaters into the DMR MARC network

    Ubiquiti Airmax point to point or point to multi-point? Not all that expensive if the lay of the land permits using these...
