3 New RMHAM Linked Sites – Installed in one day, including the updated Colorado Connection.
A crack team of 15 RMHAM team members pulled off another 3 site day interconnecting the RMHAM (front-range) network to Leadville and Vail. This push gets DMR into these areas that have not been covered with DMR until now. We (RMHAM) now cover I-70 nearly contiguously from Genoa through Avon. We installed two, new (digital) microwave hops from our Fairplay site to our Leadville and then over to Vail (Dowd Junction) with three dedicated teams. By noon on September 30, 2017, the DMR and Analog FM system were in place and ready to carry digitized voice traffic – simultaneously over the new Digital Mountain Top Microwave Network.
Colorado Connection – Vail – Dowd Junction Repeater – FM Analog 147.345 (+) PL 88.5
DMR – Vail Dowd Junction Repeater – 445.07500 (-) Color Code 7, Time Slot 1 – connects you to RMHAM Front Range Talk Group 700
DMR – Vail Dowd Junction Repeater – 445.07500 (-) Color Code 7 Time Slot 2 – connects you to RMHAM Front Range Talk Group 720
We also added new digital linking for the Colorado Connection and upgraded both the Leadville and Vail (CC) repeaters to new digital hardware! The Colorado Connection still supports FM/Analog Radios, however the new Mountain Top Microwave Linking System – digitizes that FM Analog Voice traffic into TCP/IP – VoIP packets. This new Digital Microwave Mountain Top Linking ELIMINATES the old Analog FM Link Radio System problems that has plagued SCARC Repeater Backbone for months!
