Although I live on the east coast I love to listen to all scanners including California Incidents including the second largest fire dept in the USA. I use the phone apps to listen to LACoFd and LA City fire. Can someone tell me what is the active areas of LACo. Does the scanner apps like broadcastify monitor all the divisions? Whats Does Blue 12, Blue 6 and Blue 8 cover ? Are those 3 that the entire dept or just three subdivisions ? Any recommendations on which scanner i should be listening to , to hear the most incidents in LACo as well as the other busier cities , like San Fran, San Diego, Sacramento ect.
