There are many different things:
1) To build hardware for QO-100 ground station. (This is my favorite)
2) Work on QO-100 transponder.
3) Make remotely controlled station for QO-100, without public access.
4) Work on QO-100 via internet (most boring).
So. Goals 1-3 are great and everyone is invited to do it. This is really good for HAMs. New skills and knowledge.
Goal 4. It is no so exited because you just connecting to website, server, etc and work. What is difference for QO-100 and other remotely controlled (HF) stations? I think that useless because you are using someone else gear while QO-100 is another push to build something yourself interact and experiment with transponder directly. That's the point.
While I wait for QO-100 I had a question: so I will build stations, what next? I made some TX to transponder, test my gear, fix error and TX again. Still no QSOs. Meybe some HAMs notices two carriers (1 kHz space between them) on transponder few weeks ago (feb 16 and 23). I tested my TX (WiFi booster) linearity, freq stability and signal level. I don't feel that I need to start SSB QSOs right now. Maybe later. Now I am working on DATV RF amp stuff and trying to build ethernet controlled portable station for QO-100.
