DMR, a short for Digital Mobile Radio, is an open standard defined by European Telecommunications Standards Institute for digital mobile radio. Radio amateurs around the globe has been using this standard to communicate.

The standard is defined only on the terminal side, not on the network side. Due to this, there was difficult in the early days to use repeater hardware from different manufacturers in the same network.

The problem using hardware of different brands was solved when the Brandmeister team released their server software and the site brandmeister.network.

The Brandmeister servers and their connection to each other

You can connect prebuilt repeater hardware from Motorola and Hytera as well as home build repeaters using MMDVM to the Brandmeister system. You can also connect hotspots acting not as a repeater but as a bridge between the network and a RF frequency.

My DMR-ID is 2400029. In case you want to try, feel free to give me a private call. You can also call me on talk group 2400.

Xubuntu 19.04 released

New for this release is that the 32-bit image is dropped. If you want to use Xubuntu on a 386 machine, please stay to the 18.04 version supported for another two years.

The release note can be found here.

I’ve been using Xubuntu since 2013 and I would like to take this opportunity to let everyone know how happy I am using Xubuntu. As I’m already using the 64-bit version I look forward to use Xubuntu many years to come.

Thanks a zillion to the entire Xubuntu team maintaining my favourite Linux distribution!


Upcoming activity

I plan to be QRV from SMFF-1318 on April 19th. Most likely I will be on-air on the 7 and 18 MHz using Swedish SMFF frequency 7080 kHz as well as the international WFF frequencies 7144 and 18144 kHz.

Please listen for SM0RUX!


Anytone AT-D878UV

Ooops – did I just buy myself an Anytone AT-D878UV? Obviously!

I started my DMR career with a Motorola and up until today morning I had a Hytera PD785G. So far I’m happy with my Anytone.


Julian Assange


As you might have understood online privacy matters a lot to me.

This doesn’t mean I fully agree what Mr Julian Assange say or do. The same day as Mr Assange and Wikileaks releases as many leaks about China and Russia as they release about United States and its allies, that day I will re-evaluate my perception of them.

According my opinion Mr Assange and Wikileaks are connected to the Russian government to such level that we can call them Voice of Kremlin! Sarah Harrison, deeply involved in Wikileaks, helped Edward Snowden to escape to… Moscow.

Are all the people around Mr Assange good guys? No. One of them, Mr Jacob Appelbaum, is accused for sexual abuses in the film Risk by Laura Poitras. Mr Appelbaum’s abuses is even mentioned on Wikipedia. Maybe Mr Assange is guilty to whatever he is accused for by the Swedish prosecutor?

Yes, I believe we as individuals need to be able to keep our privacy and integrity when being online. But also states and governments need to keep secrets. Therefore all governmental agencies are not per definition bad.
