>From K6JSY:

Ever wonder where the AM or FM broadcast station you're listening to 
is located?  If
so, here is the place to check it out.  You can even check out how 
much power they
are running or if they are directional or not and if directional what 
does their pattern look like.

Some very surprising information can show up.  For example I often 
listen to an AM
station in Apple Valley.  They had a fine signal here as long as the 
sun was up but
at sunset their signal would all but disappear.  I was curious as to 
what their
day and night time power was and what their night time broadcast 
pattern was.  What
I discovered was that they were non-directional day and night with a 
daytime power
of 5KW.  The big surprise came when I saw that their night time power 
dropped down
to only 20 watts!  Yikes!  I could still hear them at night but very 
poorly with
lots of QRM.  The transmitter site is located approx 30 miles from our 
place -- not
line of sight either.  Amazing that I could still hear anything of 
them at night
with their having only 20 watts of night time antenna power!
