It seems to me there are "plenty" of launch opportunities available in the 600-1000 km region but none above that.
From an Amateur Radio perspective it seems to me that for those orbits the pass
time (~10 minutes) and the range is too short. Near circular polar orbits at either 1500 km (Oscar 7) or 4500 km are far more desirable.
The CubeSat platform, although somewhat restricted in size, does provide a cheap means of experimentation. Would it be possible to build something into this platform that would raise the orbit ?

This is so on topic that it deserves to grow a life.
Since both the earth and the sun have magnetic fields it may be possible, at various times depending on the relative positions of the spacecraft, earth and sun to change the spacecraft velocity by using magnetic systems. This is an interesting subject that is sure to have been discussed before, but an internet search didn't come up with much at all. Some one on the list will probably be able to point to some research on the subject. For sure it would be a slow,computation intensive endeavor but I cannot see why it, theoretically at least, cannot be done.
