H. F. Bands

A brief outline of the usage of the short wave or high frequency (HF) part of the radio spectrum is shown below. This 'band plan' is not totally precise or all-inclusive. Its purpose is just to give a general picture of what may be found on HF, and where. The colour coding denotes usage: NOT propagation characteristic.

This band plan may have been changed since I wrote this in 1997 and usage allocations may differ between the different global radio regions as designated by the International Telecommunications Union.

For more details on HF band plans, look at the web sites of the Radio Society of Great Britain, the American Radio Relay League and the International Telecommunications Union.
