Thank YouThe ZTRON goes over the wide area network, basically the county Wi-Fi microwave system. If the stations ZTRON is not working the quick call system is used. You will hear chief’s, safety officers, Air Ops, hand crews, and Cal City get the over the quick call for all of their responses. Every Thursday at 10:00 A.M. or close to it, the quick call is tested for everyone with an all call. I haven’t heard anything about the wildland coordinator.
