If what you are saying is true, WCC would need a encrypted talkgroup if City of Brookfield would want to be encrypted then WCC would also need a console/ radio with encryption enabled and then all the City of Brookfield police department vehicles and mobiles would also need to be encryption enable and they share the Area 1 talkgroup with Town of Brookfield as well. it would be a big undertaking and with Waukesha County in the first stages of planning a new P25 digital radio system my bet is they maybe getting radios that are P25 compatible and also have encryption capabilities
