If you cease operation after a visit you may not even get a NOUO, it depends on the agent, who's complaining, and most importantly you. Don't give out any info, but don't be a dick about it.
There was an obsessed preacher who ran an FM op about an hour away from me. He'd get a visit, swear he'd never do it again, then be back on the air as soon as he could get a new transmitter. It went on for years before the FCC finally shut him down for good, with a huge fine to boot.
I remember seeing his final bust on the local news. I could see why the FCC went easy on him for so long. He was harmless,confused older guy living in an ancient trailer perched high on a steep hillside.
I often wonder if he was related to our pal, Al.
