Does anyone have the info for the radio system that DMSE Sports uses during a race? Not sure if they use the same system at each race but I'm interested in monitoring for the 2023 Beach To Beacon in Cape Elizabeth, ME on 8/5. This is the same company that organizes the Boston Marathon and several other road races in the New England area. They appear to set up a portable repeater on a man lift (for the Beach to Beacon anyway). The system is definitely DMR and they appear to all use XPR7550's and XPR6550's. Not sure if the system belongs to them or if they sub it out to a radio shop or something.
