Seattle-King County Public Safety Trunking System, Seattle, Washington - Scanner FrequenciesI never hear traffic from the talkgroups listed for Normandy Park. Also, I remember hearing the police on 154.415 so I'm not quite sure which system Normandy Park Police uses.
You're probably not using the right site. The local agencies are usually on dedicated sites. So for Normandy Park, you'll probably need the Seattle Simulcast site entered into your scanner.Nickcarr the TGIDs in that link are never active.
