Unless they hire him to detect rogue walkie talkies or something. Like 123 people ? Not much of a market anyway.
But now, do these people not even have electricity ? The rectifiers in an S MPS can create some high harmonics, which should be eliminated by the line filter but in practice not always.
Also, federal law requires 911 emergency service everywhere. So what is the solution ? Give them all DSL with shielded phone lines and they use someth ing like a Magicjack for a phone ?
Or maybe the people around there don't want any of this newfangled shit. Li ke "If I want to talk to my neighbor I just take my horse and buggy and go down there and knock on his door". Hmmm "What if you want to talk to someon e in New York ?", "Why the f*ck would I want to talk to anyone in New York ?".
