I am relaying this newsgroup post hoping it may be
of more general interest to you.

Ken has a functional APRS VHF rig aboard his bike in the "Tour to
Cure" for Diabetes today and tomorrow. Today they go from
Columbia, SC, to St George, SC on their way to Charleston.
They'll camp in St George, tonight,
then proceed through Charleston to James Island County Park, the
finish line.

Ken's APRS station is a walkie talkie and GPS receiver transmitting
... 5 watts to a small antenna, so you will only be able to see his last
APRS automatic reporting transmission, now 5 hours old as I
type this, near Lake Marion.
The internet links get data from repeater stations that
receive Ken's transmitter and relay it to a much wider area,
so he must be in range of those stations.
Just follow the link and you can see what other hams have done
withthe APRS to Internet link.
There is a map showing, now, Ken's bike in
someone's yard, probably a rest stop. Just below the map, the
findu.com software also shows his bike's exact location along side
some farmer's driveway in an aerial photograph of the area!
...wouldn't it be nice if the family you left at home could go to
findu.com with your ham station on the boat and see your last
transmission showing exactly where your GPS puts you, your
speed and course, reassuring them that you are OK and
moving along nicely (or at anchor in some
exotic place, making them green with envy)?"


Brian Whatcott Altus OK Eureka!
