I've been looking around at different sites and have been able to listen to a few passes of AO-91 & AO-92. I haven't had the chance to listen in on a pass of SO-50 yet. My question is, I see tons of mention of the two new birds and SO-50, but not much mention of AO-85 on the "intro for beginner" type sites out there. Is it harder to work or listen to? I would think it's easier for a newbie to try a pass on one which may not be as busy.
