Yes I saw that Ed.  Here's Spectran screen captures for the first hour:

http://w4dex.com/temp/haarp/19jan08/

Image 0033 show the silence period.  Had I not been changing the speed 
and frequency resolution I would have caught the silent period on one 
full screen.

Check out the QRMing signal on Image 0006 and 0007.  Also a few carriers 
showed all during the period.  One was off screen but strong enough to 
blank the capture.

I was using the HP3586 SLM, only because it was already hot.   I made 
the mistake of not havening the input level manually set so the input 
attenuator was automatically hunting which caused the levels between the 
terrestrial signal and the EME signal to not show true signal strength 
on the captures.  That is also noticeable on the .wav file.

Nothing heard during the second hour up the band due to strong BC and 
possibly a BC jamming signal.
