Somewhere in all this discussion about the future of AMSAT we need to recognize the work that William did on the 10cm^2 U/V transponder that was featured in the most recent Journal. Here we have a young person -- by the reckoning of most of us -- taking the very component-based approach to satellite building that has been seriously suggested as a way forward. He has made something that will fit the most narrow and most cheap form in launches today, the cubesat, and the result would fulfill our interests in analogue communications satellites.
I suppose I see this as something of a challenge for our forward thinking. As a group, how do we respond to this? I would like to see his work tested on ground, perhaps in more than one locale, perhaps in an urban environment where it would get lots of traffic. Perhaps his design could go through some sort of audit so that some of our technical team could ensure that the most performance is being derived from the least power.

This might be a good package for one or more of the ham radio balloon groups. They often fly FM repeaters; perhaps a linear one would encourage more activity from the weak signal group. - Duffey On Feb 8, 2009, at 3:52 PM, Bruce Robertson wrote:

I'd be happy to build one if it could be "kitted" at a reasonable cost.

What a "carrot" that would be to dangle in front of a university Cubesat group....
"Here, fly this RF package for free... The only condition is that it becomes available to the amateur satellite community at large once your mission objectives are met."
We should have a bunch of these on the shelf, ready to hand out as soon as a group announces their intent...

George -- I agree completely about having a bunch of these on hand. Especially if we can first make a few copies, run them in some diverse environments and just generally kick the tires in a way that most cubesat projects don't have the opportunity to.
William has provided a means of injecting a CW beacon. I wonder if 'we' could add to this, say, BPSK, which worked so well on Delfi c3, or an FSK channel.

I don't know about y'all, but I'm still blown away with the idea of a satellite being the size of the distance between my thumb and pointer finger, cubed; not even mentioning having a transponder aboard that. It's really just amazing that something so small, so far away, can actually be used to make intelligible contacts.
Let's hope that one of the future university launches (or maybe SuitSat2?) would take advantage of this technology and fly it in their cubesat.

We here at Near Space Sciences would be honored to test fly such a payload.
We ourselves have thought of such a payload for all 20 years of doing these flights. but never came up with a good set of boards.
As stated we have been doing this for 20 years now, and have 47 flights with 100% recovery rate under our belts.
