DP Why is it that I can received WCBS @ 880kc fairly well at night but
DP WABC @ 770kc suffers from phase distortion like you wouldn't believe!
DP (I'm about 175 miles from both transmitters.) They are both 50 kwatt
DP stations. And why is it that both WBZ (Boston), WBT (Charlotte, NC),
DP WJR (Detroit) and WBBM (Chicago) come in better than either of the New
DP York City stations?

Perhaps there are a few mountains inbetween you and NYC that cause
fringing effects?

WBZ in Boston is a clear channel station. I don't think they
have any pattern restrictions; they run 50kw 24/7.

Thanks to you all for your excellent information
