Radio and flight — for a quarter century.

Hi! I'm Marcin, callsign SP8MB, from Świdnik, Poland. Radio has been my life for over 25 years — professionally and after hours. I work in communications and radio, specializing in Motorola digital systems: TETRA, P25 and DMR, as well as repeaters and base stations.

TETRA is closest to my heart. I co-run the amateur TetraPoland network — from a base station and terminals to phone apps. I'm glad to pass on what I learn along the way: in talks, in conversation at meet-ups, and simply by helping those who are just starting out.

My second passion is flight. I hold a UAV operator licence (UAVO). I took part in building HELI-500 — a drone with a half-tonne take-off mass — and in R&D projects with the Lublin University of Technology, and I'm co-author of a patent for an unmanned aircraft and its docking station. I work with the Polish Air Force University (LAW) and several other institutions in the broad field of security, and I also prepare expert analyses for specialist entities.

After hours I mix it all together: I build radios, SDR receivers, hardware and software, and drones. I treat this site as a workshop on display — everything I do, in one place. And when I put the soldering iron down, riding a motorcycle is my easy way to unwind.

Have a look at the projects, the repeaters, or just get in touch. 73!
