[BC] Most powerful AM radio station....

[Richard Fry]

My first guess would be daytime, WLQV Detroit 7861 mvm
and by night WWJ Detroit 7981 mvm.
____________

But according to Doug Vernier's website, WWJ has a 1.72 mV/m nighttime 
signal in Saginaw, MI (in ~ their main lobe), while WJR has 1.99 mV/m. 
WJR, of course, is on 760 kHz with 50kW ND and an RMS of 2845 mV/m at 1 km.

So why does WJR have the stronger signal?  Does the somewhat longer path 
length for WWJ account for this?  Weird conductivities? The freqs aren't 
all that much different.
