After reading this thread, I seem to be in the minority here, but I'm not a huge fan of weather radio alarms, even with SAME coding.

A county can be an awfully big place and you're going to get woken up in the middle of the night fairly often for weather that's happening far, far away. Where I live, the city has "air raid" sirens for warning about imminent weather alerts and those suit my purposes just fine.

Bottom line is you're going to get a lot of false alarms and these things can be insanely loud. If something bad is happening locally around bedtime, we're already sleeping in the basement.
