Don't remember that but what about attaching a HamHUD II
(http://www.hamhud.net) to the D700? It does do SmartBeaconing and much
more...
73 de Juergen
P.S. Didn't test if it works but as D700 has a TAPR-like command-set it
could, may be. :-)

Cheapest solution would probably be to connect a TinyTrak III to the
MiniDIN 6-pin "packet" (i.e. TX audio, RX audio and PTT) jack on the D700.

Here is an old message I had saved about it.

Subject: [aprssig] smart beacon
Here's the first draft of the smart beacon for kenwood d700 and basic
stamp 2. For this code to work, you simply need GPS input on PIN P0,
and Kenwood db9 pin 3 to PIN P1, and grounds, of course. Yes this code
is sloppy... PBASIC does not allow for IF THEN ELSE, nor does it allow
for IF THEN / ENDIF structures. I'll clean this up RSN, but have had
alot of interest and want to get the code out fast as possible.
Smart beacon will beacon:
1. a fixed distance (actually, a number of seconds determined by your
speed in KNOTS) 2. At the moment you stop moving, and every 30 minutes
after that. 3. When you go around a curve, once you have driven in a
straight line for a few feet.
Pros:
1. stops endless fixed position beacons of parked cars.
2. randomizes posit reports w/o coordination required by GPS Slot time
methods. 3. Does not interfere with normal operation of radio (for the
most part).
Cons:
1. Smartbeacon used on a kenwood radio will not beacon when you are
talking on teh other 1/2 of the radio 2. If you are entering a message
or viewing station list, and the smart beacon wants to TX, it escapes
you from the menu. From the serial port, I have no way to know the user
is viewing the station list or is trying to enter a message. Need a
manual inhibit button. Something to put the stamp to sleep for, say, 60
or 120 seconds. Future version may query the radio to see if the user
has switched off BCN command and use that as a hold off. 3. Smart beacon
sure is chatty here on the east coast where we have many curvey roads.
Other applications I see for this are being able to power the radio on
and off.
Although teh basic stamp isn't good at watching two serial ports at
once, I'd like to be able to monitor 144.39 for information like the
locations of digi's that may be on other frequencies, or for local paths
in a given geographic area. Lots of potential here!

' Smart beaconing for the PIC processor
' Wes Johnston, kd4rdb
' Hook this to the same GPS which is connected to your kenwood radio via
a Y cable. ' The PIC processor will harvest GPRMC sentences from your
GPS. ' When this SmartBeacon device decides the time is right to beacon,
it will toggle ' the kenwood's beacon mode causing it in turn to beacon
your position. ' Plug the output of this unit into the serial connector
on the kenwood radio. ' Thanks Steve Bragg KA9MVA and Tony Arnerich
