Let me know if you get this working. I'm installing weather stations for
paraglider and hang glider sites. A 'wind talker' that can read out these
measurements on another frequency would be nice.

I just made a talking aprs weather station. using perl and liniux
What I want to do is menu drive it with dtmf.

Soon to be obsolete is a bit of a stretch. Maybe in a couple of years
you'll have a compelling reason to upgrade.

I don't think we've had any commitment from handheld developers yet on
supporting any new protocol. OpenTRAC, at any rate, should be easier to
implement on small devices than APRS.
If I had the time and funding, I'd love to develop an advanced handheld
client based on a commercial mapping engine. Unfortunately, I've got
neither. Maybe someday. For now, I'm keeping in mind the possibility of
Bluetooth support in my TNC/tracker project.

Contact KD6VPE, he has such a thing running in our area.

Did you say the above Bob? Your post made it appear as I did, but I didn't.
Anyways, whoever quoted the above left out the SA part. My mistake, I assumed
everyone knew what that was. SA, or Selective Availability was the
intentional degradation. of GPS accuracy by the U.S. DOD. The "VAN's in the
Ocean had more to do with SA I believe then any improper map datum. Here is a
link for more info:
http://geography.about.com/library/weekly/aa050400a.htm
BTW, something I just learned, "GEOCACHING", the sport of using GPS's to find
treasure trinkets, was created to celebrate the turning off of SA:
http://gislounge.com/features/aa012301.shtml
My kids love this...before we moved out in the country, we were up to I think
13 but not too many close to us now. Hey, has anyone done a APRS/OpenTrak
geocache yet? That would be COOL!
>I am sure it was a good lesson for you.
Yeah, that was my point. With SA on, the 60 foot granularity was not much of
an issue, but now with SA off and WAAS becoming standard, there are so many
new things we can do. Funny you say that, I think the day after SA was turned
off, a friend and me decided to operate "automotive IFR" We found a deserted
stretch of road, drove it once to get a track, then I drove it again ONLY
LOOKING AT THE GPS (buddy in the right seat was watching the road though!).
You can even now tell what lane on the highway you are driving in with SA
off.
The applications are endless, datamining like James has done with APRSWORLD
is just the start. Of course, the SAR folks can locate assets now to the
foot.
So that was the interest in higher precision for me.

I really think someone should talk to Kenwood directly here before predicting
this. Even in the scope of APRS, there is so much more they could do. Maybe
Kenwood could be convinced to sell/give the firmware assets to the amateur
community? Most companies are reasonable if you can find the right person.
The idea Wes Johnston had I thought was excellent, letting the user control
the display. I can really see a correlation here between the Kenwood radios
and the LinkSys WRT54G's, where the open source of the device INCREASED the
manufacturers revenue by creating a large secondary market for the custom
firmware. The hams/hackers COULD write the software, but the HARDWARE was
close to impossible to duplicate, hence the manufacturer took little risk
releasing it.
I wish I knew more about them, but I never owned one. Does anyone know how
the software prom is held in place? Is there one for the radio/display/TNC or
separate ones? Is it a E2, OTP micro or something else? I'm thinking it might
be possible to build a SMD PIC daughter board, but never seeing a schematic,
that is SWAG on my part.
Its my guess both the D7 and D700 are near end of life from a manufacturing
standpoint, so this might be the time to approach them. Certainly doesn't
hurt to try.

My recollection is they bought the tnc as a sub assembly of hardware and
code from a third party, and do not own the rights... Just my memory, so do
not take it for book...

It was thinking about that that led me to the idea about trail monitoring I
brought up earlier. At least, I think I brought it up here... the idea was
to use buried seismic sensors at critical trail junctions to trigger a
Pocket Tracker type transmitter, sending a timestamp that could be used for
SAR purposes.
