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

================================
Different frequencies, different directions, different sun angles
(even when below the horizon), different ionospheric layer heights,
different skip distances, different ground-path terrains and therefore
different ground-path loss.
