You can also run the low-end RINO up on a tall pole, connected via a
long serial cable down to a box running Xastir.  Xastir can poll the
RINO periodically and transmit APRS objects for each RINO position
that is heard.  That way SAR teams with RINO's will appear on the
GPS displays of SAR teams running TH-D7A's....  Unfortunately it
doesn't go the other way, but you can't have everything!

This might be useful for public service events also, where you have
both hams and non-hams helping.
