Saw this thread and registered just to reply. My son is on the autism spectrum and has recently become an "EAS enthusiast" (his own words). Has has 8 weather radios and yeah, they alert quite a bit. He does record them and is especially interested in the tests.
I can only say that once he becomes excited about something, he's all-in - whether that's weather radios, video games, memorizing the capital and countries of the world, etc.
He came in here while I was looking up weather stations (thought it'd be a bit of fun to set up during the holiday break), I showed him this post. He immediately recognized the video, just by the thumbnail.
So, yeah, you're describing my son to a "T". He can tell you all about the different weather radios, the different models, all of the local weather stations, where they're located, the different counties, etc. It's a bit obsessive, in my opinion, but it's just who he is. I find it quirky but charming.
