OK, here ya go.


This is about ten minutes in mp3 format (192Kb/S) as received in 
Detroit at about 1:15PM EDT, September 15th, 2013.  Receiver is a 
Kenwood TS480 and the antenna is a 6M halo (horizontally oriented) at 
about 20 feet elevation outdoors.  There are plenty of airplanes and 
some good meteor returns.  Residual carrier is around 1060Hz and 
there is a slightly lower line as well from (assumed) a carrier from 
a second station.  I believe the other faint airplane returns above 
and below 1060Hz are from the sidebands of the main carrier.

If you for any reason would like the WAV file, I can upload that as 
well.  It is around 76MB.

If you need an extended feed, I can go live for you for a couple days 
via Livestream.  If you can route audio from your sound card to your 
software (like with Virtual Audio Cable), that should work too.

Have fun!
