![]() ![]() I will focus more on some practical considerations. For example: What is DMR? What is System Fusion? I will not go in-depth into the technical specifications of DMR and C4FM, but you can check out online resources for these. Those without DMR radios can use this to get notifications or listen in when there is traffic. Transmit on this channel goes to the analog side of the repeater at 431.600 MHz. Our DX1ARM UHF ROIP Zello channel receives audio from the digital talkgroups, but cannot transmit, due to the restrictions of the BrandMeister network. These inter-links mean that when someone is talking on BM TG51518, for example, the traffic is also transmitted to the YSF room, as well as Echolink, allowing for cross-mode communication.

For example, on the database, which is used by the DM-MARC and BrandMeister networks, there are now at least 161,000 registered callsigns, and the number keeps growing at a fast pace. ![]() New forms of digital radio are gaining popularity.
