My love for electronic started in my childhood, with a metal nail in a wall socket and the discovery of AC current :) First steps and soldering with soldering iron, old tube radios and first "baby" walkie talkie. The discovery of the CB band and later 11m SSB operation, where it was possible to work DC with the whole world at that time. Thanks to local amateur radio operators I got on the HF, VHF and UHF bands. Thought the local radio club OK2KFK and contest station OL2R, I made my way to OL7M and building a large M/M contest QTH. The need for more complex controls, switching, RX antennas and other equipment led to many products on RemoteQTH.com web. Later, I started making other products in my company under the QRO.cz brand.

Now we are dedicated not only to the production for radio amateurs, but also to custom development and production in the field of RF. The next steps are also towards remote control via the Internet, IoT and other modern technologies.
