According to most part 15 oriented forums my part 15 fm station is practically a pirate operation. Unless your running a 100 mW AM FCC certified transmitter and ground system strictly by the book (part 15 rules) then your obviously a pirate fm.
Well to that i say ARRRRR! Mateys!! RF has a mind of it's own and i am sure the fcc took this into account when they wrote the rules for part 15. Even my $10 Schosche FM Modulator with no real antenna can go 1000 feet just plugged into a computer or mp3 player and it carries certification from the fcc. If i transmit more than 200 feet it is NOT because my station is blasting the airwaves with 100 watts and a high gain antenna. It is merely doing what RF was meant to do, Radiate!
