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.

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...)

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. Signal from the satellite was breaking up but i was able to hear my downlink with 5 watts for most of the past but as probably a commanding station was adjusting the levels the near end of the pass my audio became extremely weak and seems to never getting back at the AOS to TCA level.
The first morning low pass audio adjustment produce a very good and clean signal but on the second one audio appears to be muted at AOS to TCA and became extremely muted on the second half on the pass to a point where no communication was possible. It is not a signal problem but just the audio who seems to be adjusted at the right level.
No distortion has been noted too.
The only one problem i was alone for the whole pass speaking to myself...
