a good hf station costs more than many satellite stations.
V band and U band are common low freq sat bands. what is lower that those?
yes to work satellites the operator needs to learn a lot more than 
working a FM repeater on a hilltop.
more than one satellite at $6,000,000 each, how many do you want to fund?
Eagle is not a tech challenge, except perhaps the higher freq digital part.
the host satellite decides where our antennas go. they will likely 
need to be omni-directional to be of any use to use?
P4 sounds like the simplest and easiest to use ham satellite that has 
ever been thought about or built. Both for the builders and the users.
