World Music Radio 15700khz (Denmark) Heard In Alaska-AMAZING SIGNAL!

Stig Hartvig Nielsen's World Music Radio is in Denmark operating on multiple frequencies including 15700khz. The transmitter operates with 300 watts into a 3 element yagi beamed at 180 degrees due south from the transmitter site.

That 15700khz signal is heard here,(west central Alaska) surprisingly, from time to time.. I can detect a carrier and gurgles of audio now and then...... with "listenable" audio now and then with loggable/reportable from time to time

Well this past Thursday, August 7th my reception far surpassed anything I'd heard from 15700khz in the past. Take a listen to these two clips:

1853UTC- the clip by itself is pretty impressive, but listen to this one and then the next one
WMR 15700khz Thu Aug7, 2025 1853UTC.mp3

1913UTC- this one even below station operator Stig Hartvig Nielsen away
WMR 15700khz Thu Aug7, 2025 1919UTC.mp3

Big ass loop, TEF6686 radio, preamp and antenna tuner.
 
Short path almost directly over the North Pole from Denmark to you would be around 4,200 miles.

There is the possibility of long path reception via the South Pole, as you would also be in the way of the beam pattern, and at those hours it is a grayline path with very favorable propagation characteristics.

With the way the signal behaves and when it peaks, right now about 1900 and 0500, i wonder if its grayline headed south.

Can you explain what you mean by the signal's behavior? Do you possibly mean the rapidity with which it fades? I have sometimes wondered if that is a signature symptom of multiple oceanic/ionosphere bounces in a signal's path (i.e. of very long paths).

Very nice catch!

when it peaks, i think when it peaks here is right before sunset and right after sunrise there... and the peaks dont last long

Those are the typical characteristics of grayline reception.

During winter months here in Houston I can hear stations in East Asia around local sunset on frequencies that would otherwise be too low to propagate. When I plot the signal path and compare it with a day/night map, I find the signal is going through areas in twilight or very low sun angles.

The reception “window” might be an hour or maybe two at the most in such circumstances.

with WMR for me, the window of really stuff stuff is even less than an hour.

With inconfidencia the listening window is quite big sometimes, BUT....... the peak is sometimes 10-20 minutes at best

What's "grayline reception"?
