If you want anyone with the Kenwood all-in-one APRS Radios to see you and
many of the other APRS software,  then the UNPROTO must begin with one of
the more common generic callsigns:  BEACON,CQ,QST,ID,ALL, etc..

The best format to use that is guarantennd to be seen by everyone is to
put the grid in the data field as >GG##GG/g etc

But you have to type that in every time.  its a mess.  We never could get
all the aprs authors to agree and so  who knows...  I think Grid square is
probably best, but its just that the Kenwoods wont see you because it is
not part of the APRS spec.
