Repeaterbook.com understands that DMR is a digital format that operates at a bandwidth of 12.5 kHz. DMR can control access to the repeater with a color code. It is much like CTCSS, but the signal is sent outside of the digital voice frame.
DMR incorporates talk groups and the available talk groups are tracked by Repeaterbook.com. They can belong to large networks, which is also tracked by Repeaterbook.com.
