DMR Repeater

CFMC's UHF DMR repeater is a Motorola Mototrbo™ system: 443.400MHz, +5.0, Color Code 1. Further DMR information regarding the repeater is on our Repeater Book entry. It is connected to other DMR repeaters via  c‑Bridges™ at K4USD and from there on to other networks such as Brandmeister.

An excellent turorial is "Amateur Radio Guide to Digital Mobile Radio".


Inexpensive DMR Radio

To help more people to begin to use DMR on the CFMC Repeater System, Bob Conrad, W8SCK, has found the Radioddity GD-77. Besides DMR it is great for FM on VHF and UHF, and is less than $100.

Here are his instructions for a newly purchased GD-77. He has provided a Codeplug for CFMC repeaters, to download it to your default download folder click here: Get Code Plug.

There are various sources of information on the web. Watch instructions and reviews on Youtube or check out this FAQ
