Hi Drew et al 

I monitored the last pass with three radios.  On the standard 70cm downlink.  A three foot primestar dish with transystem 3731aa downconverter to a TS700A transceiver.  Finally a "portable" 20 turn helix with a IC-W32a connected to a Keps 13-LNC2-PH downconverter.  The primestar dish and 70cm antennas tracked automatically via a LVB tracker.  With the 20 turn helix I stood out in the driveway (w/rain) waving it around at the sky (neighbors already look at me funny).  I was surprised how sharp the 20 turn helix is, 20 degrees off the satellite and it's almost gone.  Solid full quieting signals on all three receivers, obviously the dish was stronger.  With monitoring all three receivers and tracking doppler manually I had no time to do any transmitting.  A very busy and entertaining 10 minutes!  I have a couple of pictures of the lash up should anyone like to see them, email direct.  S o any of you AO-40 (sobsob) fans dust off your S band gear!
