What you are hearing
Dispatch traffic is terse and preliminary — calls are described before anyone has arrived, details change constantly, and the people discussed have not been charged with anything. The guide to radio codes covers the shorthand, and fire and EMS radio explained covers alarm levels and apparatus.
Feeds run a few seconds to a minute behind real time, and quiet stretches are normal — an area this size genuinely goes minutes without traffic at night. If a feed seems dead, this covers how to tell.
