Amateur Radio Band Plans and Spectrum Guides
Explore resources on radio spectrum, including amateur radio band plans, frequency allocations, and guides for various radio activities and services.
Understanding the radio spectrum is fundamental for all ham radio operators, from new licensees to seasoned DX chasers. It defines where amateur radio activity can take place, outlining specific frequency allocations for different modes and operational practices. Knowing the band plans helps hams avoid interference and make successful QSOs, whether on HF, VHF, or UHF bands.
This category provides essential resources like band plan charts for various regions, including detailed US HF amateur bands, which guide operators on where to find specific modes like Hellschreiber or FT8. You'll also find broader radio spectrum allocation charts, such as those from the ARRL, illustrating how frequencies are shared among different services. These tools are crucial for planning antenna projects, setting up transceivers, and ensuring considerate operation across the airwaves.

These frequencies have been adopted into the bandplans of each IARU region to be a focus for emergency communications in their areas. They are not absolute frequencies but instead are centres of activity and emergency communications may be found around 20kHz from these centres. Some countries may maintain other emergency frequencies in their own bandplans due to local requirements, QRM etc -
