Putting ISS first in the hop path seems to be the best strategy since
ISS is above ANDE and the ISS antenna is Earth facing. Since ISS has a
fairly high output, it is more likely to be heard by ANDE than the other
way around. The draw back is that since ANDE is much harder to hear, one
on the ground may not know if they had a successful hop through ANDE if
no one hears the relayed packet.

Thanks Joe.  Yes, that is the best idea...

But come to think of  it, ANDE does not have the best ears
either...  Oh well.  Glad to hear ISS back up.  Maybe if someone
can catch PCSAT-1 on a mid day sunny pass and ISS, they might
get a double hop...
