Ham Amateur Radio Technician Practice Exam 2026 – The Complete All-in-One Guide to Exam Success

The frequency range typically used for digital modes on the amateur bands is High Frequencies (HF). Digital modes such as PSK31, RTTY (Radio teletype), and FT8 are commonly operated on HF bands, especially because these frequencies can effectively propagate over long distances and often provide better performance during periods of low solar activity.

HF encompasses bands from 3 to 30 MHz, making it suitable for a variety of digital communication methods. The characteristics of HF allow for both local communication and long-range communication, which is advantageous for ham operators using digital modes. Frequencies in this range are utilized extensively for amateur radio digital operations, as they provide favorable conditions for data transmission.

While VLF, UHF, and microwave frequencies do support various forms of communication, they are not as commonly employed for digital modes within amateur radio practice, particularly for the general operator. VLF is mainly used for very long-range communication but is not practical for typical digital modes. UHF frequencies are often used for local or line-of-sight communication and have unique applications like repeaters but are not primarily associated with digital modes. Microwave frequencies, while supporting digital communication, are more specialized and not as widely used for standard amateur digital operations. Thus, HF is the most
