I had a problem hearing the pass.  I see I made it into the bird.  I used a
grid parabolic 23.5 x 39.25 x 15 inches with a keps.it downconvertor/preamp.
I could hear some stations fading in and out, but just wasn't strong enough
to hear them all or myself.

That antenna seemed to work well for AO-40, but seemed light on this try.
Next good pass, switching to a 17 turn Directive System circular
polarization antenna.  Seeing if my receive will be better for AO-51

Any opinions on the grid vs. cp?

Heard this evening so far on V/S:

I made an interesting recording of the S band transmitter last pass with 
WinRad and my SDR-IQ. The signal peaks about 45 db above the noise! This is 
with a 3 ft dish with a patch feed, preamp at the feed, and keps.it 
downconverter to a hamtronics converter to the -IQ.

I'll make the recording available to anyone who'd like it, and the software 
to play it is available for free at http://www.winrad.org/ . The catch is it

is about 530Mb. Maybe someone has a website they would put it on? Otherwise 
if you want it, send me a SASE and blank CD or DVD and I'll make a copy for
