Sri the delay was about 7 seconds...not 15.  I listened to this station for 
about 15 minutes.

I know nothing about how this but maybe it bounced back from an approaching 
solar wind storm?
lets see: 7 seconds to get the signal there and back would place the 
"reflecting 
storm" at a distance of 7/2 seconds away from us that would mean a distance of 
300 000km/sec x 3.5 sec = 1 050 000 km.
The solar wind speed now is about 400km per second, not sure what it was when 
the LDE was observed,
but if it was 400 km per second, and the storm hit the earth 30 minutes later, 
it would mean that the front of the storm was
about 400 x 60 x30 kilometers away, that would place it at the start of the 
LDE's at about 720 000 Km.
The error is 1050 000 - 720 000= 33 000 km, now maybe with the correct solar 
speed and accurate distance calculations, based on accurate observing, it seems 
possible, or not?Maybe the signal is not reflected from the front itself but 
from somewhere deeper in the aproaching storm?

Now, lets wait for the flames from our very wise members!
Kind regards,
