Nate, you are kidding, of course!  With AO40, apogee ~35M, as I 
remember, at apogee we
  could talk to about 90% of ones hemisphere...From San Diego I 
worked Durban, South Africa,
not too far from Madagascar, my antipode.

I think three would be needed to cover the world, but with "both" 
hemispheres I can't imagine there would ever be a problem...

There were times when a portion of the band would sound like 20 
meters during a sunspot high, but in my experience I never failed to 
find a "hole"...

How about other AO40 users??  Any problems having a QSO because of 
band congestion??

About the poorest ham radio experience I've had in 52 years was with 
the low orbit 2 user FM birds!!!
