I tried the 13:40-ish pass, and also feel that the audio was low... I'm only working with a quarter-wave ground plane at the moment, and it was only a 10 degree pass for me. I heard a couple of other stations, one of which was off-frequency on the uplink. We'll see what it's like later on a higher pass.
George, KA3HSW PS - Luc: I heard you come back to me on HO-68 last night, but then there was a deep fade and we never completed our exchanges. (It's a little hard to concentrate on satellite operating when the Bears are actually WINNNG a game...) ----- Original Message ----- From: "Luc Leblanc" <[email protected]> To: <[email protected]> Sent: Tuesday, December 29, 2009 4:45 AM Subject: [amsat-bb] Re: AO-51 mode change and recommendation [snip] > On the first 3.9 deg morning pass i was able to hear F6BYJ and an ON > station my own downlink was quite distorted even with any > signal/modulation level. > > On the second pass signal peak at S9 plus 20 but my downlink aidio was > rather weak.
