Think the FCC will buy it?
What if they come around and say they are sure you
had a few peaks over 1600 watts?
I am sure they are just waiting down the street from my house,
measuring my pep....
Hope they don't measure the FM broadcast transmitter I have,
so I can listen while doing stuff around the house and yard
with a walkman, its over a watt I think...
