Sounds like a pirate. You're allowed to run 1/10th of a watt (100 mW)
without a license and with certain antenna restrictions under Part 15
of the FCC rules.


On the FM band the FCC allows only 250 microvolts/meter at 3 meters. This
works out to about 10 microwatts. The 100mW figure is assumed by most
because that is what the old Part 15 walkie-talkies, and AM transmitters
were/are allowed. Part 15 allows different power levels on different bands
of frequencies... I believe up to a watt or two at lowfer frequencies.
