I don't think the Part 15 rules specify usage so much as transmitter
power.  Someone earlier in the thread posted the TPO limit for Part 15
- I forget exactly what it was, but I'm pretty sure it's much less than
1 Watt.  At any event, it's much less than what would be needed to cause
any noticeable interference on the aircraft band.

Some pirates use Part 15 transmitters (legal) coupled with a power amp
to boost the signal strength (which makes it not legal).  That might be
why that one pirate was saying he's "Part 15" when the range of his
signal leaves no doubt that he is not.

Why couldn't a licensed broadcaster sell a transmitter on eBay to another
licensed broadcaster?  Happens all the time, I'm sure.  For that matter,
is possession of a high-power transmitter without a license for same
actually illegal if it isn't being used?
