Radio services with primary status

{{Quote|have full rights to use any or all of the radio frequencies that have been allocated to them, unless modified by a footnote to the international Table of Frequency Allocations. Such a footnote can specify countries in which a service may not operate or can specify technical constraints such as maximum levels of power allowed. When two primary services share the same frequencies, they must coordinate their use to ensure that interference is minimized.
