Hello
Hi Bob,
To all you AO-7 fans. We appear to have a sick bird. We should feel blessed in having such a well performing satellite for several years, considering it is older than some of it's users. The audio is distorted and cw sounds bad, running absolute minimum power.
I used AO-7 yesterday evening and all seems well except the normal AO-7 gargle. But when you take this in consideration and don't use to must power or talk the fast is it still a nice bird to use.
Any thoughts or suggestions are solicited.

Could the solar panels on one particular side be failing? Are there any regular patterns to the performance?
... and so continues the next chapter of most interesting satellite we have! ----- Original Message ----- From: "PE0SAT" pe0sat@vgnet.nl To: w7lrd@comcast.net Cc: amsat-bb@amsat.org Sent: Tuesday, July 07, 2009 2:08 AM Subject: [amsat-bb] Re: AO-7???

The experience I have the last couple of weeks, is that when AO-7 is comming towards me everything works great but when it is going away from me, it is very difficult to use the bird.
No idea what the reason could be?

Hi Jan, Auke,
Probably polarization. Do you have a circularly polarized antenna? If so, try the other direction. I had very different results RH and LH; the non-default position was by far the best for me in the second half of the pass on Field Day. This was just for the downlink; my uplink is linear, so I don't know how that side reacts.
