This Parrot has been on the air now for over 7 weeks and  has proved that
it is a viable low-cost, tiny 10m Satellite mode that can fit into a
softball sized satellite.  I have had QSL's from as far away as
Australia.  THe reason I have left it on after the initial test was
because the 20 second parrot module is only rated for 100,000 r/w cycles.
That is 46 days and we are now past that milestone.  I will probably keep
it on for another 45 days to see the 3 dB point?
