Band Ranges

• HF 3 MHz to 30 MHz
• VHF 30 MHz to 300 MHz
• UHF 300 MHz to 3 000 MHz (3GHz)
• Microwave and other bands above 3 GHz

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 160 metres, 80 metres, 60 metres, 40 metres, 30 metres, 20 metres, 17 metres, 15 metres, and 10 metres. (Although 160 meters is often considered a Medium Frequency (MF) band, we lump it 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, and 3 centimetres.

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 (for example, SSB, FM, Digital, ...).
