Our Roots

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.
