Yes, Michelle does a great job. I should point out that the Phase 4 Ground Terminal Development is a separate project from the Cube Quest Challenge project. There are many similarities and the two teams are working closely together to develop compatible systems that will allow the hardware from either project to inter-operate in all respects other than possibly dish size. If successful this could set the standard for future high altitude AMSAT satellites. Since the work on the Cube Quest Challenge by the ASCENT team involves space systems, the release of certain information is restricted by U.S. law. This is one of the reasons very little information is released about satellite hardware and transponders as work progress'. The ground terminal will not be used in space so there is no problem talking more freely about it. If you follow what is happening on he ground terminal you can get a pretty good idea of what the transponders will be like.
