HF Bands

There are a number of amateur HF bands used worldwide, although the bands and frequencies legally available vary from country to country.

HF bands used today include 80 metres, 60 metres, 40 metres, 30 metres, 20 metres, 17 metres, 15 metres, and 10 metres. (Although 160 metres is a Medium Frequency/MF band, it can be lumped in with the HF bands for simplicity.)

VHF/UHF/Microwave Bands

VHF, UHF, and Microwave bands and frequencies available to amateurs vary more widely from country to country than HF bands do.

Amateur bands used today include 6 metres, 4 metres, 2 metres, 1.25 metres, 70 centimetres, 33 centimetres, 23 centimetres, 13 centimetres, 9 centimetres, 6 centimetres 3 centimetres, 1.25 centimetres and Bands above 24GHz.

Band Plans

Within three regions around the world, different "plans" are agreed upon by Amateur Radio Operators to divide up the authorized band into sections. Each section is targeted to a specific operating mode (e.g., SSB, FM, Digital, etc).

Region Band Plans

From the IARU website.

Region 1 encompasses Africa, the Mediterranean, Europe, and Asiatic Russia

Region 2 encompasses North America, South America, and Greenland

Region 3 encompasses India, Australia, Southeast Asia, China, Japan, New Zealand, and Pacific nations.
