== 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 [[Modes|mode]] (for example, [[Modes#Single-Sideband Modulation (SSB)|SSB]], [[Modes#Frequency Modulation (FM)|FM]], Digital, ...).
