Hmm, we must be blessed on this side of the globe.  2m is still quite
useable in the cities, only major problem is the pager intermods, and the
occasional noisy computer.  However, I'm planning on going up the bands.
Got a 2.4 GHz antenna or 3 teed up.  Still have to build up a connverter,
and a transverter for Mode L.

Plenty of kits anyway, and antennas can be either home brew or surplus.

I think microwave will become the norm for high altitude sats like AO-40 in
the future, and V/U (B/J) will retain some popularity among the LEOs, where
path losses are less severe, and Doppler shift is a greater concern.

On the contrary, you've given me a really good excuse to go up the bands!
:-)  I've always had an interest in microwaves, but my terrestrial prospects
are limited by my situation.  Not so for satellite microwaves, the way is up
(literally :) ).

> Don't be microphobic! Its not rocket science - honest! (pun intended!)

Hehehe, last time I looked, rocket science was involved in getting the bird
up there. ;-)
