The big deal is that this is 2007, not 1907 or 1947.
The ridiculous thing is that some people want us to act as if we are still
using 100 or 50 year old equipment. Guess what? We're not.
Using mixed case is demonstrably easier to read. That's why we don't print
our books using all upper case. And why the only places you'll find people
using all upper case are when net newbies type messages after apparently
being incapable of turning CAPS LOCK off, of from guys who haven't quite
accepted that we're living in the 21st Century, and want everything to be
as bad as it was when *they* were young and had to hand-blow their own
6L6's from beach sand.

Ok fine thanks for the information,well all what we have learn and done is
because of following the work of the usa naval academy Bob and his work as
he have said aprs is just not tracking but more to it,while you do aprs you
can at the same time do all other stuff that the radio can do while looking
at your aprs hi hi.
Ok the software we are using here are APRS+SA,WINPACK,UI-VIEW,AGW TRACKER
these are the aprs software we are using and running 5 pc with them hi hi
so nice to hear you visit the web site soon i will put up all about what
we have done for you benefit

Basically you just decode the AIS traffic (9600 bps GMSK) from marine
vhf band per the AIS specification and re-encode suitable parts of the
information to form an APRS packet. You probably want to cache some
information at the conversion point as well, as static data (ship name,
dimensions, etc) is sent less often in AIS than location updates. And
you'll probably want to do considerable rate-limiting, if 1200 bps APRS
on the band is involved. A 2-channel AIS network has 4500 time slots (~
location updates) per minute. That's a 100-fold difference in capacity
compared to APRS.
I just haven't really gotten the point in it, why would you want to see
AIS targets in the APRS network? Maybe that can be useful in a special
event situation that includes both APRS stations and AIS equipped ships,
but in the general case? Ok, this is a hobby, so "just for fun" is a
valid answer as well.. just watch out for those that might not like it.
I've heard stories of some players in the marine world that consider AIS
information to be "secret".

An excellent choice. Too many people think of the D700 as just an APRS
radio for just vehicle tracking, but they are overlooking the 20+ years of
APRS NOT as a vehicle tracking system, but a local, tactical, real-time
data channel for exchange of data about *everything* that is going on in
ham radio surrounding the operator (without the burden of the old
connected-packet) system of the 1980's and 90's.
We just used the control head of a D700 on a clipboard this weekend to
collect event scores from hams with the APRS D7 HT's as score-entry devices
at boy scout checkpoints at a camporee. It worked beautifully and
seamlessly with the event and even the non-APRS inclined operators at net
control welcomed the ability to read incoming scores at their leisure on
the clipboard rather than under the stress of 20 voice operators calling in
their scores by voice. See the web page:
http://www.ew.usna.edu/~bruninga/aprsevent.html
Other things that show up on the front panel of the D700 radio:
1) Other mobiles location, distance direction and speed
2) Local APRS WX station data, temps, wind, rain, etc
3) FREQUENCY of the locally recommended travelers voice repeater
4) FREQUNECY or node number of nearby ECHOlink or ILRP nodes
5) OBJECTS for Hamfests, Nets or Meetings in progress
6) OBJECTS showing any traffic accidents or slow downs
7) Traffic speeeds at known choke points
8) Frequency and direction of any satellites in view
9) etc.
And being dual band, and with TNC for 1200 and 9600 baud, it can receive
data from amateur satellites directly, with no PC or any other display or
accessory. During a good PCSAT-1 overhead pass, I typically could see as
many as a dozen other stations making contacts. (though PCSAT-1 has
recently gone back in hybernation for months)...
In otherwords, The D700 (and D7 HT's) front panel is supposed to be your
window on the ham world around you. It can display what I call over 40
"tiny-web-pages" of information of local value to the traveler when he
enters an area, or whatever a local user might need to know at any time
anywhwere.
For info on this local display initiative, see:
http://www.ew.usna.edu/~bruninga/localinfo.html
So many things we could do. So little time...

Are you using the D700 in packet mode or APRS mode?

pkt mode,but the tnc need to be set up right or else you can end up with a
dead radio,some tnc default have to be put on and some taken off also there
are tnc setting that are not in the manual but in the radio you need to set
right.
while in packet mode you still communate in aprs with aprs station.
