Yes, I thought the same thing. Unfortunately Kenwood doesn't let you
do that. Too bad they don't give a good interface to the radio/TNC
when the thing is in APRS mode, as this would be the sort of thing
that is trivial if there was an interface (it would also be trivial
to extract waypoints properly into some of the proprietary formats
such as Garmin).

Agreed, but for $7 and no license, you can't really beat it right now
(I got the radios out of a bargain bin at Wal-Mart - they are
garbage, but I don't care if the unlicensed user runs one over with
their car either). But yes I would have had second thoughts if I
didn't also have a cell phone!
