EAS receiver

You hear the EAS tones all over the place, on local radio, weather radio and more. Has anybody heard of a packet decoder that will input this information into your computer? I think it would be easy to do. They you could program the computer to graphicly show the watch/warning on a map, so you don't have to go thumbing through your maps to find the locations. Once built, it would be a free source of local watch/warnings. you could even program the computer to alert you based an any criteria you select.

Has anybody attempted this yet?
I may just experiment with it amd see what I can come up with on my own.
