Since the mid 90s when SAME codes rolled out for NOAA weather radio system, there's been a constant low level nation wide problem with people transmitting "funny" SAME codes like hurricane warnings in north dakota and so forth. It was pretty obvious security issue when the system was released, and the fake alerts usually make it into the news as "news of the weird" rather than "OMG someone has hacked the system" type of story. There is no way to "patch" or fix the system by the nature of its design, all receivers have to trust that any transmission is genuine. Obviously cheap radios (SDR?) are just going to make the problem worse until NOAA alerts are essentially useless. Of course now there's cellphones and their broadcast emergency messages, so I would not be surprised to see the NOAA alert system discontinued in a couple years. Although SAME sounds like a horrible idea, it was well intentioned in that the radio transmissions can carry 30 to 50 miles so people would ignore all warnings given that statistically most of the warnings wouldn't apply to them (sort of like Amber Alert fatigue), so they added all this digital stuff to specify the exact problem (why?) and exact zip codes (good idea).
