Amateur radio

Band plans and frequency allocations

Through ITU agreement bandwidth has been set aside for amateur transmissions. Amateurs use a variety of transmission modes, including Morse code, radio teletype, data, and voice. Specific frequency allocations are a matter of record and vary from country to country and between ITU regions.

The ARRL has a detailed band plan for US hams on their website. For ITU region 1, RSGB's band plan (PDF) will be more definitive. RAC has a chart showing the frequencies available to amateurs in Canada. The Wireless Institute of Australia has charts for Amateur frequencies for Australia.
