Editing Co-channel interference (section)

== Overly-crowded radio spectrum ==
{{Original research section|date=May 2022}}
In many populated areas, there just isn't much room in the radio spectrum. Stations will be jam-packed in, sometimes to the point that one can hear loud and clear two, three, or more stations on the same frequency, at once. In the USA, the [[Federal Communications Commission]] (FCC) propagation models used to space stations on the same frequency are not always accurate in prediction of signals and interference. An example of this situation is in some parts of Fayetteville, Arkansas the local 99.5 FM [[KAKS]] is displaced by [[KXBL]] 99.5 FM in Tulsa, Oklahoma particularly on the west side of significant hills. Another example would be of [[Ashtabula, Ohio|Ashtabula]]'s [[WKKY]] 104.7 having interference from [[Toledo, Ohio|Toledo]]'s [[WIOT]] 104.7 FM on the [[Ontario]] shore of Lake Erie, as well as [[Woodstock, Ontario|Woodstock]]'s [[CIHR-FM]] (on rare occasions), which is also on 104.7 FM, due to the signals traveling very far across [[Lake Erie]]. The interference to WIOT from the operation of W284BQ, translator, has been resolved by the FCC. Effective October 18, 2011, it must cease operation.
