Welcome to our freeband radio community!

This website is an initiative of an enthusiastic hobbyist radio community, whose primary goal is to provide mutual support and assistance among members, as well as to help all those who have chosen radio operation as a long-term hobby in their lives. Our aim is to facilitate community connections and the thorough mastery of radio operation fundamentals—including etiquette rules and technical knowledge—through our continuously expanding, versatile services.

On this site, we also maintain a carefully moderated callsign database, which is regularly checked and updated by our community moderators. Please note, however, that callsign database services are provided exclusively for QTH locations in Hungary.
