Thomas,

Which station are you tuned too?  Jim Creek at 24.8kHz, La Moure at 25.2kHz? 
Jim Creek may be shut down. La Moure is working fine. Orientation from you 
to the receiver may have much to do with how strong the SID appears.

What kind of receiver did you build?  Any on this list?



like a solar flare.  Many satellites detected it and the ionosphere had a 
prompt response, December 27, 2004, 21:30:26 UT.  It took almost 45 minutes 
for the event to complete:
