UNDER (Summits on the Air) is a program for radio amateurs and HF listeners, supporting portable operation from mountains and mountain ranges. The SOTA program is designed so, so that everyone can participate – not only tourists. It offers two types of diplomas: for activators (of, who climb to the top) and hunters (who work from home, or they are currently activating another peak).

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 and OM0AAO.
