PROBLEM TO BE SOLVED: To obtain a surer channel by adding a channel control section to a conventional multi-channel radio equipment so as to reserve a prescribed frequency interval of operating channels or over thereby relieving load of an antenna installation condition and of in-case high frequency sneak path countermeasures. SOLUTION: A channel control section 6 always monitors channels used by all radio equipment sections 2. In the case of making communication by each radio section 2, it accesses the channel control section 6, which selects a channel to keep a prescribed frequency intervalΔfmin from adjacent channel frequencies of adjacent radio equipment sections 2 or over, and the access radio equipment section 2 makes communication at the selected channel. Thus, a frequency intervalΔf is increased for investigation of prevention of a high frequency effect, a load of in-case high frequency countermeasures and of an antenna installation condition are relieved and then a surer channel is obtained.
