AO-40 was an incentive for me, though I never got beyond monitoring 
the 2m beacon in the early days after launch and before the incident 
with the 400N motor.  I did collect a lot of good telemetry though

I do agree, more linear birds would be a good thing, and the idea of 
"sharing" with FM might work well in these parts, where it can be 
hard to find anyone else on, and FM might be the difference between 
having someone to talk to, and enjoying a conversation with yourself! 
:)  Traffic density over VK/ZL can get very low at times, so for us, 
FM is often a plus, although I'm interested in playing around with 
SSB too.  A "hand me down" and recent upgrades now mean I have more 
than enough gear for the SSB birds.

Unfortunately, LEOs can't solve the problem of vast distances meaning 
little chance of variety - all I've ever worked on satellite is VK, 
ZL, P29 and 3D2, but we have to make do with what is practical. :-/
