[amsat-bb] ANS Special Bulletin ANS-116.01 AMSAT-NA Opportunity for Rideshare to Geostationary Orbit

[Robert McGwier]

Too achieve the vision we had for EMCOM, the ground terminal will almost
certainly have to support C4FM so as to support long haul back haul of
EMCOM from the P25 devices in the impacted disaster area.  I am patient.  I
view this launch as an experiment where the Americas get a facility DIRT
CHEAP that no one has provided and if we play our cards ride,  this awesome
but possibly suboptimal to perfection opportunity will lead to a nearly
perfect opportunity.

Michelle has been rabble rousing for this for some time.  She's right and
glad you mentioned it.  We need a volunteer to work on C4FM code to make
this happen and a GREAT thing for AMSAT to do which will benefit ALL of
amateur radio and beyond.
