Re: [amsat-bb] Satellite Inquiry

[paolo.pitacco@xxxxxxxxxxxx]

Hi all!
Bill, a very interesting question ...  but I ask to know dimensions, max 
weight and power availability for this project.
Before choosing a mode, we need to know (not perfectly but very well 
defined) structural constraints for
antenna dimensions ...
A good ideas is to design an onboard transponder for wich a very simple 
groundstation should be use.
SSB is more efficient than FM, as channel bandwidth and power used; FM use 
is driven only by portable
equipments commercially available (commercial reasons only) not for 
technical reasons.
Many people enjoy today on experiencing QSO via "old" AO7 or AO10 
satellites; why not repeat this today?
