For Europe, Africa and Asia the MW band consists of 120&nbsp;channels with [[Carrier wave|carrier frequencies]] from 531 to 1602&nbsp;kHz spaced every 9&nbsp;kHz. Frequency coordination avoids the use of adjacent channels in one area. The total allocated spectrum including the modulated audio ranges from 526.5 to 1606.5&nbsp;kHz.<ref>{{cite report |title=United Kingdom Frequency Allocation Table |date=22 June 2017 |page=16 |url=https://www.ofcom.org.uk/__data/assets/pdf_file/0016/103309/uk-fat-2017.pdf |via=ofcom.org.uk |access-date=August 22, 2017}}</ref> Australia uses an [[AM expanded band|expanded band]] up to 1701&nbsp;kHz.

The range above 1610&nbsp;kHz is primarily only used by low-power stations; it is the preferred range for services with automated traffic, weather, and tourist information.
