Here's a quick background on how EAS SAME headers work.
Since the mid-90's, a a device has sat in the headend room of every TV / FM / AM station that listens for EAS SAME signals on neighboring stations and, if the specified information matches the predefined filters for location and type of emergency, rebroadcasts the emergency message on its local station.
Since I'm trying to flex my coding skills right now, I wrote a Python script that generates these tones! Tested and is correctly interpreted by my SAGE EAS ENDEC.
Please please please please PLEASE use this responsibly. Did you just buy an old ENDEC on eBay and want to put it through its paces? This is the script for you!
Don't use this to hack / exploit anything. I made this for funsies in a few hours. Please use it accordingly.
Also if you create a fork of this repo, please credit the original project :)
