Standard 9600 baud AX.25.  No special software.  Just need raw packets.on
447.605

PSAT2 and USNAP1 were delppyed together and have identical external shape
and so should be in same orbit, but due to mass differences, USNAP1 should
be LEADING PSAT2.  We need to know by houw much.  Since PSAT2 is likely
object 44354, and 44355 is very slightly leading (by 1 minute) that could
be it.
