      Welcome to the specialized section for Short Waves (KV / HF), which forms the very core of the amateur radio hobby on the CQ.sk portal. This discussion forum is dedicated to all enthusiasts of communication on frequencies up to 30 MHz, covering all classic amateur radio bands from 160m to 10m. Whether you are among the experienced DXers tirelessly chasing rare expeditions or a beginner just discovering the magic of ionospheric wave propagation, this place is made for your community.

      Share your practical experiences in constructing efficient HF antennas, tuning transceivers, or comparing the technical parameters of modern SDR devices. We discuss the specifics of operation in various modes – from traditional telegraphy (CW) and voice transmission (SSB) to modern digital modes like FT8 or amateur radio teleprinter. Shortwaves offer a fascinating opportunity to establish connections all over the world with minimal power, which requires a deep understanding of propagation conditions and technical skill. Join the discussion, ask forexpert advice or inspire others with your successes in international competitions. Your contributions help build a quality information archive for the entire Slovak amateur radio community.

    • Very High Frequencies
      The Very High Frequencies (VHF) section is a dedicated space on CQ.sk for all amateur radio operators whose interests extend to the bands od 50 MHz vyššie. Či už vás fascinuje „magické“ pásmo 6m, stabilná prevádzka na 2m a 70cm, alebo technicky náročné mikrovlnné frekvencie, toto fórum je vaším ideálnym komunikačným priestorom.

      Discuss building high-gain Yagi antennas, low-noise preamplifiers, or linear amplifiers to increase effective radiated power. However, VHF operation is not just about local contacts. It is a world of fascinating phenomena, such as reflections from meteor trails, auroras, sporadic E layers, or challenging EME contacts via the Moon.

      Zdieľajte reporty z VKV závodov, skúsenosti s digitálnymi módmi či prácu cez amatérske satelity. This category serves as a comprehensive knowledge base for every operator who wishes to continually push the technical and geographical boundaries of radio wave reach. Add your contributions and actively develop a vibrant Slovak VHF community.

    • Technology
      Welcome to the Technique section, which is the beating heart of the CQ.sk portal for all enthusiasts of amateur radio construction and experimentation. This discussion forum serves as an open workshop and a shared knowledge bank for anyone who is not afraid to pick up a soldering iron. Whether you are a beginner operator looking for pomoc s prvým zapojením, alebo ste skúsený rádioamatérsky technik, toto miesto je stvorené pre zdieľanie overených postupov a technických inovácií.

      You will find space for detailed discussions on designing electronic circuits, reviving complex projects, modifying commercial transceivers, or building your own antenna elements and measuring instruments. Are you interested in classic tube technology, modern SDR solutions, or integrating microcontrollers into your radio station? Share your questions, answers, and ideas that will help others tackle technical challenges.

      Together we build a quality archive of expert knowledge that inspires current and future generations of Slovak radio amateurs to active technical creation and continuous improvement of their equipment. Your expertise and curiosity constantly push the boundaries of our shared hobby forward.
