OpenMHz
OpenMHz plays public radio transmissions with individual saved calls and a searchable listening history.
Choose it for following supported public systems rather than receiving official emergency instructions.
Its stated thirty-day archive permits returning to earlier transmissions instead of only hearing a live stream.
Keep in mind: Coverage depends on participating systems, and recordings can be delayed, incomplete or unavailable.
