Wow, those pirates must be really filling the FM band so much that ya can't hear your local CHR or NPR station.
I understand their dislike of unlicensed operators -- I mean, if someone is running a station that is putting out interference in the Air Band, I get that.
But the number of pirates I've heard about in my metro of around 4 million people are very, very small. And I've never heard one. Ever.
And the weird thing is the FCC is heavy duty about these FM pirates, but some ham can spew hate and filthy language in the middle of the 40 or 20 meter band flagrantly (and I've read it can happen on the 2 meter band in some cities) and they rarely, if ever, get investigated.
