Radio amateurs most often encounter a superhet receiver, which uses signal processing on the auxiliary frequency, so-called. intermediate frequency. Direct mixing receivers are also suitable for beginners, which are structurally simpler. SDR receivers have been expanding in recent years, which are characterized by high intermodulation resistance and the ability to set the properties of the receiver by software.

Thank you for visiting this portal designed for all radio amateurs from OM and OK.

We bring you current information from the amateur radio world, however, we do not want to be narrowly focused on one area, therefore, new articles from each circle will be added to these pages practically daily, which concerns us HAMs.

We would ask everyone, who can contribute their articles, ideas, stimuli, to be actively involved in building this portal. It's not a portal to those, what they created it for, but for all of you.

If you have any questions, please contact the administrator at: admin@cq.sk. Thank you and we look forward to meeting you at the band! 73 by OM0RX IS OM0AAO.
