Topband: WLW

[Bill Aycock]

I agree that mark makes valuable contributions, but I wish he had not put it 
out under the "WLW" Logo.

I could agree that some of the messages on this thread might have been
boring, but I find Mark's posting VERY interesting pointing to an actual
propagation effect not fully explained by propagation models.

I HATE it when Topbanders get bored; thing like this "WCKY<WLW" etc flood
out.

1.7 megawatts out of WLW was no doubt the highest power run by anyone in the
Western Hemisphere on medium wave.


Duba, Saudi Arabia runs 2 megawatts on 1521 kHz all the time.  No wonder
that it often screams in here on the coast of Massachusetts around local
sunset, as in this recording:

or this one:
<http://www.qsl.net/wa1ion/audio1/dx_1521_saudi_arabia_20081029_2300z.mp3>


1521 has proven to be a useful propagation indicator to the Middle East, as
is the UAE station (R. Farda) on 1575 with 800 kW and Kuwait (R. Sawa) 1548
(600 kW).


The signals are at least 15 dB stronger at seashore sites than at locations
even just 5 to 10 miles inland, especially if the intervening land is sandy
or rocky.  A receiving antenna that is substantially elevated would cut
those losses some at the inland site.
