DMRX was a community of amateur radio operators who wished to experiment and explore with the DMR digital voice and data mode of operation. In addition, we formerly provided services for the community such as DMRX Watch, formerly known as, the DMRX Core, formerly NATS, and multiple user and repeater database and reporting functions.

DMRX Watch was a last heard list for the DMR community which displays the obvious information that you would expect and also includes signal strength, loss information, and was completely sortable and filterable. Additionally, we used to produce reports of the Top 10 users, repeaters, talkgroups, and networks, based on talk time. We are no longer adding new functionality to Watch based on suggestions and feedback from the community.

The DMRX Core was a pair of redundant cBridge devices dedicated to transporting talkgroups to and from other cBridges which provide connectivity to repeaters. The goal of the core was to ensure that a simple hardware or software failure does not cause a large disconnect between systems and to provide the most efficient path between endpoints which reducing the occurrence of call collisions in an effort to provide the best possible user experience.

DMRx Ending Operations

Opinions of the masses posted on Facebook and that their view of DMRx is no longer an effective resource for distributing TalkGroups and called for re-engineering.

I was suprised that before a constructive request to increase the server resources or bandwidth that the community expressed interest in re-engineering a replacement for DMRx. It turns out that effort became our exit from serving the DMR community.

After 6 years of serving the DMR Community it was time to get out of the way of those whom desire to replace DMRx, the DMRx admin decided to contribute to the re-engineering effort by getting out of the way. A planned Shutdown was announced.

After midnight on the 2nd of May, 2020 DMRx servers stopped providing connectivity to Talkgroup sources. It appears that the re-engineering effort is sucessful as there is little or no traffic on the DMRx Network.

There are a few lingering connections that their C-Bridge administrators will need to redirect to the new re-engineered sources.

It had been fun, it had been alot of work, it had been a considerable investment and it has benefited untold thousands of amateur radio operators over the last six years. Best of all are the relationships that were made to last longer than DMRx would.
