That's so true.  Down here, we used to _ragchew_ on UO-14 on late 
night (around midnight local) passes.  I've even had passes where I 
was the only station on the bird, so all I was doing was listening to 
myself call CQ. ;)

FM birds do work well when the ham population under them is low. 
:)  On SSB, I found it hard to get a QSO due to the lack of stations.

So for us Down Under...  FM LEO and SSB for the HEOs seems to work best...
