Note: I am not in any way affiliated with Mid-Nebraska Scanner. This Twitter feed is embedded here as an additional resource/insight into local happenings.
The Scanner page contains an almost-live audio stream of the local public safety radio channels around the Kearney/Buffalo County Nebraska region. Along the sidebar, there is a list of the standard 10-codes used by the Nebraska State Patrol.
Some disclaimers and things to note:
Disclaimer: the scanner page will remain up until it is no longer feasible. If it becomes an issue, or I receive a request to take it down, I will.
