Claim:
1. A radio communication device that is a subject station, comprising: a determiner configured to determine that a voice communication frequency of a voice band to be used by the subject station for a voice communication with a distant station is permitted to be changed to a voice communication frequency of a selected distant station, the voice communication frequency of the selected distant station being included in predetermined information disclosed by the selected distant station, when the predetermined information satisfies a predetermined condition set in the subject station, and that the voice communication frequency of the voice band is not permitted to be changed to the voice communication frequency of the selected distant station when the predetermined information does not satisfy the predetermined condition; and a frequency change controller configured, when an instruction to change the voice communication frequency to the voice communication frequency of the selected distant station is issued, to perform a control to change the voice communication frequency if the determiner determines that the voice communication frequency is permitted to be changed, and to perform a control to maintain the voice communication frequency without changing the voice communication frequency if the determiner determines that the voice communication frequency is not permitted to be changed, wherein the determiner determines that a communication condition is permitted to be set for the subject station, in a case where information relating to a communication condition other than the voice communication frequency included in the predetermined information of the selected distant station, satisfies a communication condition included in the predetermined condition, the communication condition being a communication mode, and the radio communication device further comprising a communication condition change controller configured to perform a control to change the communication condition when the determiner determines that the communication condition is permitted to be set.
