Chris --

It's really not that bad. On HO-68 or AO-7 you get at least 3x that
time. FO-29 varies, but it also provides quite a bit of time. And
there's a distinct lack of a 'crowd' on the linear birds. Even on
VO-52 you can have a nice conversation because you can hear

The LEO scene is a different set of challenges, but they can be fun to
overcome, and the same kids who are interested in the keps will
*really* love to hear their own voice bouncing off of VO-52 :-)

As I see it, there is good news and bad news in this. For years, the
bad news was that rides to space have become so commercialized that
'we' can't get freebies or ultra-cheapies anymore, and we simply can't
afford to pay the proper price.

The good news, only recently, is that this commercialization is
starting to provide full-cost opportunities that might be within our
financial range. But these would require us to perfect many aspects of
cubesat-level miniaturization, and would require much more advanced
ground stations.

Of course, if some inexpensive opportunity arises, the AMSAT-DL P3E
satellite is available.
