PROFESIONAL AND AMATEUR RADIO PROJECTS

by JAN SUSTR, OK2ZAW

About brand QRO.cz

We are a small company engaged in the development and manufacture of telecommunications and other electronic equipment. We develop elements for radio amateurs and professional customers in the field of high frequency waves (up to 26 GHz) and also IP-based remote control devices.

AMATEUR RADIO: I have joined to building OL7M contest station many years ago. As it grows we need more and more technical tools, parts and advantages to be better. There are some projects - not only for OL7M - but also for many BIG Guns, Contesters, DXers, SWL, Satellite Operators etc. I hope you can find something interesting also for you.
