This sounds like an excellent experiment for you to try and report your results in an article for the AMSAT Journal!

I wonder if anyone has actually done any studies after all these years on propagation's through this bird. AO-07
I find it in the past couple weeks soo interesting on how varied the level of signal strengths can be on very similar passes.
Where one pass, vs another are almost identical, yet one will be full of stations, and the next one all I hear is my own CQ.
BUT... that difference can be all made by just who is actually on the air.
BUT.... then take two passes that are almost identical, and ignore all the other people, and pay attention to just your own signal, where on this pass my sig is soo weak that 90% of the time I'm hearing nothing, then next pass that is very similar I am actually moving the S meter the signal is sooo strong.
And in theroy, this is all Line Of Sight communications, the losses from one pass vs another should be the same.
Yes polarity can be an issue, but I cant see it being the reason for the whole pass duration.
Very Interesting!
