Hello Eric,

Excellent questions. Let me see if I can answer them.

The purpose of the survey (the Tuesday challenge and the survey in the newsletter) is to find out what the current feeling is on assumptions about the end-user price (not the component cost) of the ground station.

There are multiple configurations, which affect price and cost. There are many phases of the project, which also affect price and cost.

$350 is attainable for certain configurations during certain phases of the project.

We will deliver a cost and price estimate, with supporting analysis, at the October AMSAT Symposium. This will require answering a lot of questions between now and then, and I'm extremely interested in (and agree with) your input.

The meeting that you are referring to - the summer 2006 meeting at Qualcomm - is part of the foundation of the effort. We've built upon it and are progressing forward from there. Based upon the work done in 2006, the work done by the team since February 2008, and the work that is scheduled for the immediate future, we expect the cost to be between $350 (bare bones) and $1000 (complete system). 

The preliminary presentation for the October Symposium will be released this week, and I'd like to open the subject of cost and price analysis for work between now and October. What other aspects and facets of the problem most interest and concern you? What questions do you most want to see answered?

I must have missed that one.  Does $350 include the antenna, antenna
mounting system, LNA, and the rest of the radio?  As I recall from our
meeting at Qualcomm, we wanted a complete radio _system_ for the
ground station.  Is this assuming a host based s/w radio, or are you
thinking about running this on something embedded?  Are you assuming
that this is a professionally assembled and tested unit, or a
do-it-yourself kit for people who think soldering fine pitch surface
mount is a pleasant way to pass the time?  Not that I wouldn't _want_
it to cost $350, but that seems too cheap to believe for an assembled
and tested solution, in a box, ready to go.
