Editing FM broadcast band (section)

===Center frequencies===
While all countries use FM [[Channel (broadcasting)|channel]] center frequencies ending in 0.1, 0.3, 0.5, 0.7, and 0.9&nbsp;MHz{{Citation needed|date=March 2025}}, some{{Which|date=March 2025}} countries also use center frequencies ending in 0.0, 0.2, 0.4, 0.6, and 0.8&nbsp;MHz. A few others{{Which|date=March 2025}} also use 0.05, 0.15, 0.25, 0.35, 0.45, 0.55, 0.65, 0.75, 0.85, and 0.95&nbsp;MHz.{{Unspecific}}

An [[ITU-R|ITU]] conference in [[Geneva]], [[Switzerland]], on December 7, 1984, resolved to discontinue the use of 50&nbsp;kHz channel spacings throughout [[Europe]].<ref>{{cite web|url=http://ukspec.tripod.com/specbw.html#b87|title=UK Radio Frequency Bands|website=ukspec.tripod.com|access-date=19 March 2018}}</ref>
* Most countries have used 100&nbsp;kHz or 200&nbsp;kHz channel spacings for FM broadcasting since this ITU conference in 1984.
* Some{{Which|date=March 2025}} digitally-tuned FM radios are unable to tune using 50&nbsp;kHz or even 100&nbsp;kHz increments. Therefore, when traveling abroad or importing receivers, stations that broadcast on certain frequencies using such increments may not be heard clearly{{Citation needed|date=March 2025}}. This problem will not affect reception on an analog-tuned radio.
* A few countries, such as [[Italy]], which have heavily congested FM bands, still allow a station on any multiple of 50&nbsp;kHz wherever one can be squeezed in.{{Citation needed|date=March 2025}}
* The 50&nbsp;kHz channel spacings help prevent [[co-channel interference]], and these take advantage of FM's [[capture effect]] and [[radio receiver|receiver]] [[selectivity (radio)|selectivity]].
