Is consistency in FM frequencies possible for radio stations?

Answer

The current frequency plan has been in effect since 27 May 2004. It is a collection of agreements whereby radio stations are allowed to broadcast their signals on a specific frequency in a specific region or province with a specific power. To avoid interference with neighboring countries and other regions, a limited number of frequencies are used in each region or province. The national channels also use different frequencies per region or province. Otherwise, not only would a signal at close range fall on a radio in your home on a specific frequency, but at the same time a signal that has been traveling for much longer and would be perceived as disturbing due to the delay.
