After seeing your post, I setup for this afternoon's AO-7 pass. However, perhaps more than the other voice sats, I've found that there is a LOT of variation between passes with how well I hear AO-7. Sometimes I've caught conditions where the downlink was extremely strong and sometimes I can barely receive it.

Today's pass was the latter... I think I only heard 2 stations well enough to copy their entire call sign. Saw my signal several times, but if I had tried to make a contact it would have had to have been a quick one. I didn't try since my uplink would have been so difficult for anyone to copy.

So, if my reception accurately depicts what conditions were for this afternoon's pass, I don't think it was a good one to pass any judgements about how your setup is working. One of these passes when it's like 2m simplex from someone in the same room will be a lot more helpful. Just have to get lucky and catch one of those. They're a lot of fun when they happen!

This thread has most of the details, as well as a screen grab of this afternoon's attempt. I'm wondering if I am actually getting in just fine, but the RTL-SDR dongle is just too pathetic to pick it up. But if that's the case, then it would mean that the other signals are blasting into the transponder. Did anybody have a qso stomped on this afternoon by "K3RLD testing"?

My thought was desense from your transmitter. What's the antenna setup? I think I saw that answer on QRZ or somewhere, but don't recall. 73, Drew KO4MA
