Mark, Thanks for pointing out the de-orbiting requirement; it’s a tough one. But just thinking out loud: what about using the SmallSat EP that Samudra Haque mentioned in an earlier post. I skimmed the paper he and his co-authors produced. Equipping a cubesat with an EP unit looks like an elegant way not only to put the bird up (using the ISS as the launch platform) but also to bring it back down. RayKN2K

The launch costs, while significant, are beside the point. The biggest issue with HEO satellites are the regulatory challenges. AMSAT and international partners could build and get ready for launch such a satellite within a few years, just as they did with AO-10, AO-13, and AO-40. But they would not get a license to put it into orbit in the current regulatory environment. The technical and financial challenges can be met, but the licensing requirements are killing us.
Just this month, a couple of NASA's own satellites had to be scratched from a launch because they did not meet the increasingly strict de-orbiting requirements for a license to orbit. (https://spacenews.com/nasa-cubesat-bumped-from-rideshare-launch-because-of-o...) And right now, even stricter international regulations are under consideration.
If NASA is having trouble meeting these restrictions, you can imagine how high the bar is for a non-profit organization of amateurs. Pipe dream all you want about launch opportunities, but if you can't get the necessary permits, it's just that -- pipe dreams. -- Mark D.

Rocket Lab's definition of "sensible cost" is $10 million. That is indeed a bargain price for a dedicated HEO mission. Do we think that AMSAT could raise that amount of money in a sensible amount of time?

With the recent success of Capstone and the Rocket Lab Photon spacecraft, it may be possible to put a transponder on a Photon mission to GEO at a sensible cost.
