the problem is that the legal ones cannot go very far. the FCC rules
limit the field strength to something like 150uV/meter at 3 feet
(IRRC)

I believe Part 15 specifies the limit of a "10-foot"
antenna, and 100mW of power to the "final".

I built a Ramsey electronics tunable fm transmitter
it was explained to me that the fcc does not care about "transmitter" power
or antenna design or size
the part 15 is based on measured feild strength at some set distance from
the antenna
I have not used mine sinceI built it out of fear that the fcc will impound
and auction everthing else audio I own saying it was support gear for the 1
watt trasmitter I built(this is within thier rights as well as something
like 25,000$ fine per occourance)
it just became to risky to use
