The biggest thing it takes is getting a ride. If you were hitch hiking would you be able to get a ride if you had a sign “Destination GTO and have to carry this large bomb with me”.
You have to also take enough fuel (bigger bomb) to keep you in one spot for many years. You have a large ratio between the fuel (grams) needed to get you to GTO and the amount required in your slot. Your slot in space is moving at a high velocity with changing gravity, other forces, and a driver that has to make constant adjustments.
You have to have the ability to develop the systems by having the people or paying for it also. AMSAT has lost some key people which helped with this in the past.
AMSAT has lost spacecraft due to issues with rocket engines.

What does it take to push a craft in GTO to GEO ? I guess that there is a single thruster involved. Do you think any lab will donate one? The GTOs should be relatively inexpensive to get to. I can't see why Icoms and Yaseuas ant loosen their purse strings for a project like this. I have heard that they sold in excess of 20,000 IC-7300 last year alone. That is just one of their radios, and that is just one company. Then there is everyone from the tiny HF signals all the way to Kenwoods and Yaesu. Hams have patronized their products for long, at times, well past their sell-by-date. The FT817 was kept alive mostly by the sat operators. If each picks up a million dollar ticket, with matching grants, 10 M USD isnt a big deal. It is also big business for them. An 8 MHz slice of space spectrum could otherwise cost them a few times over. - f

That quote reminds me of this blog reposted to Hackaday:
Ham Radio Needs To Embrace The Hacker Community Now More Than Ever

"I think the service should be devoted to technical achievement and experimentation. Many of the other activities that amateurs engage in can be done in other personal radio services, but technical experimentation is, and should remain, limited to the amateur service."
Today we can extend the phrase "other personal radio services" to include Internet and cellular services as well.
So, what could we do in a geostationary orbit that won't simply be a duplication or an enhancement over what's already been done for decades?
I think it would be neat to have the equivalent of a WebSDR in geostationary orbit to see exactly what can be received well beyond the Earth's ionosphere. The results could be rather surprising...
