Selecting a unique name is easy.  Just browse aprs.fi/NAME where NAME is
the location one wants to use for the given digipeater.  If nothing else in
the world matches, then the name is unique.  If there is a match, then
change the name to make it unique.

Being able to instantly see what are humans (ham communicators) among a 100
deep list of callsigns (half of which are digipeaters or other inannimate
objects is a useful capability when trying to actually communicate using
APRS.  It also makes it instantly obvious where one's signals are being
digipeated (by location) instead of some random collection of letters
(callsigns). Bob, WB4APR
