In Sedgwick County lingo, "Common" refers to one of the two PD talkgroups - either "South/West Common", or "North/East Common". There is also a "Sheriff Common" talk group for LE, and EMS has "EMS Common" as well. The LE in most of the small municipalities have their own version of "Common" too, but they will usually refer to it as something else, such as "Go to B". The WPD Common channels are most often used for officer to officer traffic regarding details of calls that are too lengthy to give over the Dispatch talkgroup, or to pass on information that is usually not appropriate to give over the Dispatch channel, like where are we meeting for dinner? The WPD dispatchers monitor the Common talkgroup for their bureau, and will occasionally communicate with officers on there as well.
