I wrote Trunk Recorder because I was curious about what my local fire station was up to and I put together the original version of OpenMHz because I figured other people might want to listen to the recordings too.
The latest version of this site makes it easy for other people running Trunk Recorder to share their recordings. I am hoping that making it easier to listen to what our local fire, police and EMS have to go through everyday will lead to a greater appreciation for all the work they do, which goes largely unseen.
The audio from each system is archived for 30 days, so you can go back and listen to events you may have missed.
