I live in NE Penna, and one of my favorite
nighttime MWDX's was WCCO in Minneapolis. ( 830 )

Recently, the signal is completely blocked
by a signal from Reading Pa. also broadcasting on 830.

I thought that WCCO was a "clear channel" station.

Maybe I misunderstood the meaning of "clear channel"
I thought they were all hi-powered stations,
and if they did share a frequency, it was because
they were a couple thousand miles apart.

Can someone enlighten me ?
