Is that thing really 15 KW?
This kind of thing didn't exist when I was into CB in the early 70's It's got to be total homebrew. I get the impression that it's got to be dirty, but if these guys are in competition, wouldn't they want all their power in a tight frequency range?
BTW, on a related subject. I was listening to 75M the other night, and some guys were talking about some ham they called "Jersey Joe" who got caught running 28 KW. Is that something that really happened, or is it just a tall tale that keeps getting bigger?
