This is not a "official" Emergency way to operate, just common sence. If doo doo hits the fan and Internet, cable TV, phone service and cell services are out. Use your car radio, pick the FM band, and push the scan button. If nothing then try AM. If there is nothing on either band it might be the apocalypse. Time to get right with God.
1 tv transmitter (with 4 hd channels) 2 FMs (us and a religious translator) and no AM's audible during the day. About the only thing to remain on out of all of that in a power outage would be us.
