[aprssig] The best resolution of position from APRS

Here is the bottom line on this debate.  I have no more
time for this incessant refusal of XASTIR to move beyond
the problem.

1) XASTIR insists on sending the depricated obsolete
compressed object /item format that has been known
to not work on the thousands of Kenwoods for many 
years which  reprsents 85% of our mobile APRS community 
that sees objects in their mobiles.  This undermines the
communications on-air integrity of APRS when mobiles
cannot see these objects.

2) Yet there are 3 ways XASTIR could UPGRADE and
transmit objects to 1 foot resolution if they wanted
to instead of just bashing kenwoods.

a) use KISS mode and send the object as a $GPGGA packet
b) Send the object in 3rd party format as a $GPGGA packet
c) IMplement the new APRS 1.1 !DAO! format.

To me, This insistnce on using the obsolete/depricated 
compressed object/item format is what is holding back 
progress, missleading the community, and bashing a
very useful product that almost half of us depend on for
our APRS picture.

If these authors would instead update their software to
the APRS 1.1 spec which does try to be responsive to
user needs then ALL users will be able to see what is on the
air at a come-as-you-are event.
