It can do messaging, it just has no user interface of its own. If you plug
it in to a dumb terminal (I use an old Palm III) it'll send and receive

I think Rich Painter's uSmartDigi beats it for flexibility, but I don't
think it's remotely configurable like the T2. The main limitation is the
lack of buffer space - you don't want to use the T2 for digipeating TCP/IP
or anything.

Better to use the GPS display to see when someone's coming, IMHO.
Especially when you can check the waypoint comments and see if they have a
calling frequency listed.

I have made two or three -- in the past -- oh -- say -- 6 or 8 years! Lee
Dahlen was one, Bob Bruninga was another. And in the middle of nowhere,

In "APRS" mode, the D700's internal firmware creates an APRS terminal on
the control head's screen and sends nothing to the serial port. The serial
port WILL accept commands to configure the radio (load/read memories,
switch bands, change freq and PL, dim the panel, etc) and to change TNC
mode (APRS, PACKET or OFF).
In "PACKET" mode, the D700 just acts like any radio connected to a TNC.
What comes out of the D700's DB9 serial port is about the same as you would
get from a TNC2 in normal conversational mode, plus GPS passthrough from
the dedicated GPS port ala KPC3+.
You can even live dangerously and command the D700 into KISS mode, but your
external device must be really fast on the draw to accept data as soon as
it appears, in order to avoid the dreaded KISS overrun from a far-too-small
buffer in the '700s internal TNC.

Probably the simplest thing would be to leave the T2 stock and feed it
fixed-level receive audio from the D700's 6-pin Mini-DIN packet/data
connector. (The D700 has connections for an external TNC even though it
has one internally.) You can take your pick of raw unsquelched
discriminator audio or squelched, de-emphasized RX audio, both at constant
level.
The only disadvantage is that the audio on this jack follows whichever side
of the radio is selected for mike PTT, meaning that anytime you are NOT in
a voice QSO on the right side, you need to push the left vol control to
transfer PTT to the left side.

.... by default, anyway. There is a command you can send to put it in a
sort of monitor mode so that you can see lots of data. U think the NMEA
sentences pass through, but unfortunately the APRS data is in some odd
internal format and I've never tried to reverse engineer it so that it
could be translated into an APRS data stream. Here are a few examples of
the specific strings that pop up when a station is heard:

Subject: RE: [aprssig] APRS Icons on Garmin Receivers
I started thinking about how to set this up with my T2, and unless there's
a way to make the garmin TX NMEA and RX garmin binary, this probably won't
work (it could if you've got an extra serial port on your GPS, or have an
extra GPS). Unless the T2 will translate Garmin binary into NMEA and I've
forgotten?
I may still set it up just for grins, with the old Trimble GPS engine
feeding NMEA to the D700 and use the Garmin MAP60C with the T2 for pretty
icons on the maps.
On the D700 mini-DIN connector: it sure seems to me that letting it
follow the PTT setting on the control head was a boneheaded decision. It
makes it useless for anything I've ever wanted to do with it. I would
_love_ to have access to the TNC via rs232, or to that side of the radio
via the mini-DIN, and still use the D700's APRS application.

Subject: [aprssig] gps sneakers ?
Do these units transmit to a satellite or to a cell phone tower???
Engineer: GPS shoes make people findable By KELLI KENNEDY,
Associated Press Writer
Fri Feb 9, 12:45 PM ET
Isaac Daniel calls the tiny Global Positioning System chip he's embedded
into a line of sneakers "peace of mind." He wishes his 8- year-old son had
been wearing them when he got a call from his school in 2002 saying the boy
was missing. The worried father hopped a flight to Atlanta from New York
where he had been on business to find the incident had been a
miscommunication and his son was safe.
Days later, the engineer started working on a prototype of Quantum
Satellite Technology, a line of $325 to $350 adult sneakers that hit
shelves next month. It promises to locate the wearer anywhere in the world
with the press of a button. A children's line will be out this summer.
"We call it a second eye watching over you," Daniel said.
It's the latest implementation of satellite-based navigation into everyday
life - technology that can be found in everything from cell phones that
help keep kids away from sexual predators to fitness watches that track
heart rate and distance. Shoes aren't as easy to lose, unlike phones,
watches and bracelets.
The sneakers work when the wearer presses a button on the shoe to activate
the GPS. A wireless alert detailing the location is sent to a 24-hour
monitoring service that costs an additional $19.95 a month.
In some emergencies - such as lost child or Alzheimer's patient - a parent,
spouse or guardian can call the monitoring service, and operators can
activate the GPS remotely and alert authorities if the caller can provide
the correct password.
But the shoe is not meant for non-emergencies - like to find out if a teen
is really at the library or a spouse is really on a business trip. If
authorities are called and it is not an emergency, the wearer will incur
all law enforcement costs, Daniel said.
Once the button is pressed, the shoe will transmit information until the
battery runs out.
While other GPS gadgets often yield spotty results, Daniel says his company
has spent millions of dollars and nearly two years of research to guarantee
accuracy. The shoe's 2-inch-by-3-inch chip is tucked into the bottom of the
shoe.
Experts say GPS accuracy often depends on how many satellites the system
can tap into. Daniel's shoe and most GPS devices on the market rely on
four.
"The technology is improving regularly. It's to the point where you can get
fairly good reflection even in areas with a lot of tree coverage and
skyscrapers," said Jessica Myers, a spokeswoman for Garmin International
Inc., a leader in GPS technology based in Kansas. "You still need a pretty
clear view of the sky to work effectively."
Daniel, who wears the shoes when he runs every morning, says he tested the
shoes on a recent trip to New Jersey. It tracked him down the Atlantic
Coast to the Miami airport and through the city to a specific building.
The company also has put the technology into military boots and is in talks
with Colombia and Ecuador, he said.
But retail experts say the shoe might be a tough sale to brand-conscious
kids.
"If (parents) can get their kids to wear them, then certainly there is a
marketplace. But I think the biggest challenge is overcoming... the cool
marketplace," said Lee Diercks, managing director of New Jersey-based Clear
Thinking Group, an advisory firm for retailers.
The GPS sneakers, available in six designs, resemble most other running
shoes. The two silver buttons - one to activate and one to cancel - are
inconspicuous near the shoelaces.
The company is selling 1,000 limited-edition shoes online and already has
orders for 750, Daniel said.
Parents who buy the pricey kicks don't have to worry about their kids
outgrowing them fast. This fall, the company is unveiling a plug-and-wear
version that allows wearers to remove the electronics module from their old
shoes and plug it into another pair of Daniel's sneaks.
