Note the date on the announcement. To my knowledge, v1.2 has not moved since then. Ask me sometime about the problems associated with not including someone fluent in weather monitoring in that group for the weather elements in the spec.

The APRS spec would likely contain the specification for any and all data
strings.  Looking at Bruninga's site I see that they are working on v1.2; I
have been reading v1.0.1.

My guess is that anything xastir writes to APR-IS (igate or not) would be
within APRS spec "tolerances".

I have been working on a packet decoder in c to help me understand actual
data strings better.  You are welcome to it if interested (though I am sure
that something similar is already in xastir).  It is more "human readable"
than "machine optimized" since it is a learning endeavor...

Though I may be completely wrong ;)

Good morning,

Can some one point me to the place in the xastir where data gets written
to the APRS-IS.  I am interested in how objects, posits, messages etc
are written and not necessarily IGate-ing, but it may be the same code.
   Pseudo code would be good too.  I have an idea for some SAR specific
messaging stuff and am trying to understand how the APRS-IS works.  I
have not had much luck looking at the documentation on
http://www.aprs-is.net

Thanks es 73,
Dave
