Please allow a little perspective on AO-51 from someone who has worked it for a long time and from all over the world.
I left the USA in late 2003 for a work assignment in Darwin, NT (Australia as VK8OE), where I talked to myself for over a year on AO-51 mode L/S (I took my AO-40 setup and it died before I could work it as DX). I did the same thing on ISS packet, having great keyboard QSO's with myself. The only sat contacts I ever made while VK8OE was on AO-51 in mode V/U FM (mobile while at work) with a few ops on the other side of the continent (VK5ZAI, VK3FGN, VK2TU, VK2TRF, et al).
Ditto in the UK (M0GOE), where every pass sounds like the one from last weekend--or worse. I gave up working FM satellites for several years while in Europe--and I had an Arrow! The only operating time on sats I had for a number of years was a Mexican cruise in 2007 where 100% of the succesful contacts were on AO-51. I am repeating that cruise in two weeks and hope to work a few of you on this venerable bird.
I spent most of last year in Papua New Guinea (V29OE) and the only satellite traffic I ever heard was on AO-51 V/U FM (VK's of course). I never completed a QSO as I just could not make it with a bad battery in my FT51R (less than a Watt) and a whip antenna.
Sorry for the rambling.... the bottom line is birds like AO-51 are a great resource to us and finding ways to manage them for everyone's benefit is a challenge. They are a priviledge to work, not a right. Control of them is not a democracy. And regardless if you consider this a casual interest or a seriously competitive sport, it is still just a hobby.
The thing that really annoys me, though, is that I saw Drew's posting, I wrote down the new uplink frequency, I had it in front of me on a sticky note, and I still didn't connect the dots when I couldn't hear myself in the downlink! I deserved to miss that grid :-)
