Actually, both ARISS and PCSAT2 would work, but only
3 low passes a day?.  But it would be better  if we could 
just get the ECHO  satellite to enable digipeating, then 
he'd have it made.  ECHO covers Alaska 11 times a day!  
All he would need  is a TH-D7 HT with his GPS plugged 
into it and it set to  9600 baud.

And since this is on the digital channel of ECHO, it would
not interfere at all with FM voice modes at the same time.
This kind of event is ideal for amateur satellite live
digital relay...
