An instruction to enter a scanning mode may be received at a communication device. The communication device may participate in several talkgroups. A determination may be made that at least one of the talkgroups is active. In response, the communication device may be set to a first active talkgroup. A determination may be made that a predetermined time has passed since the communication device was set to the first active talkgroup. In response, a determination also may be made that at least a second one of the talkgroups, other than the first active talkgroup, is active. In response, the communication device may be set to the second active talkgroup.
