I can't figure out what's wrong here. I listen for AO-7 on the past your
were talking about and was not able to here it at all and it went as
high as 89 degrees here. I thought maybe the pass times were off but
listen well before and after the times and still did not here it.
However, I hear all of the other satellites at the appropriate times.
Was AO-7 in A or B mode? Usually I hear AO-7 horizon to horizon (except
directly overhead) with a Ringer II vertical. I'm missing something
here. I enjoy working AO-7 now I seem not to be able to hear it.

The call was WA4 (or, at least, that's what I copied), but I didn't catch the suffix. The signal faded slightly, and I didn't ask for a repeat. That's embarrassing, and I apologize to the operator for that. When he called me, AO-7 was below 35 degrees. I reported a 589 to him, and he gave me a 559, which exceeded my expectations. When we finished the QSO, AO-7 was at 28 degrees elevation to my location, and I faded into the noise.

Given the compromises I choose to have with a fully portable station, that's not to bad for milliwatts.
