Well thanks everyone for the feedback. We were right. :)
Its amazing that the solution was this simple.
Now I have the Garmin Etrex mounted on the motorcycle along with the THD7
and the Ipaq showing turn by turn information and receiving the waypoints
directly from the D7 on the mapping screen.
To think I would have used a second GPS unit for this.
When I have the new RAM mounts for the D7 and Ipaq Ill take pictures and
place them up for all interested to see.
Thanks Again
best regards
Julian

Does anyone know of the smallest tracker for APRS ?
Anybody want to volunteer their project as the smallest ?

Can I make a comment about the LED's.
I think Scott is on the right track. You really only need yo look at them
for traouble shooting.
After that you close the box up and shuv it under the seat.

Some may find a application I am using to provide GPS data to multiple
operations interesting.
I have been using a program called REDIRECTOR supplied by LANTRONICS. The
Redirector creates a virtual comm port. Whenever one of the two programs I
run plus the external marine VHF DSC requests input from the GPS they are
directed to the virtual port where the GPS data is streaming.
More specifically, I run a navigation program called The CAP'N. The CAP'N
receives the GPS data and displays the boat's position and track on the
chart. In addition I can plot a course with any number of waypoints and
direct the CAP'N to control the boat's autopilot to maintain the boat's
position on the planned track. The second program is WinAPRS which utilizes
the HF side of a KAM+ which controls the Icom M800 marine SSB. The third
operation is used in an Icom M602 marine VHF. The VHF port of the KAM+
sends the GPS data to the VHF radio which in turn provides my boat's
position data via DSC. New safety regulations require vessels to be
equipped with position transmission capability if a MAYDAY is sounded.
A Garmin 48 supplies the data to the laptop and from there it is redirected
to the 3 applications. The system has been working flawlessly for the past
2 years.

For compactness of the whole package, it's hard to beat the PocketTracker
with a Deluo. I run mine with basically 3 "blocks": the PocketTracker
(combined TinyTrak3 and transmitter), the Deluo, and a 4xAA battery pack
for the Deluo.

There's also gpsd, which does a similar thing. You can connect any
number of applications to it, either from the local machine or
across the 'net, and get GPS data. Xastir has support for this
built-in, as do a lot of other apps. gpsd is free. I don't know if
it runs on Windows.

Make sure that only one transmitter is talking to the GPS. If you
have both the THD7 and the Ipaq trying to drive the receive line to
the GPS, you'll either have problems with them talking, or perhaps
damage either the RS-232 transmitter in the THD7 or the Ipaq. You
can put a switch in line to select which one should talk to the GPS.
I can see reasons to have each talk to it at different times.

For mobile use, you're probably right. For portable use, I want to
turn on the LED's every so often just to make sure the darn thing is
still running.

Hi Scott,
I also have the Garmin 16. The 18 is built just as rugged as the 16 at
half the price. It looks to be well sealed. I would not hesitate to have
it on top of car in driving rain. The bottom half is made of a rubber
type material that is nice. Just sitting on my dash it did not want to
slide around. On the bottom center is a threaded insert fot fixed mount.
I'm going to order 5 more of them It locked in the first time in
about a min, thereafter, it locks in about 10-15 seconds.
I had it laying on the dash and temp only got about 110F for a few hours
but no problems. Hope this helps.
Roger

I do that with a Magellan 310. One stream goes to the D7 GPS port.
From there the signal goes through the TNC back out to a notebook
running APRS. The second stream (in parallel) goes through a DB-9 to
USB converter into the same notebook running Street Atlas. The only
trick is to select the right GPS device in Street Atlas.

I don't know why, but when my home APRS station beacons, I can hear
the packet on the D7A, but nothing is displayed. If my home station
digis someone else's APRS packet, it will then display. I think this
must be in the settings of the D7A. Can anyone tell me what needs to
be changed?
Thanks,

I second GPSD. I use it in a commerical application of mine, and it really
is nice. It has a simply command line interface (you telnet to it) in which
you can poll for altitude/lat/lon or also a RAW streaming output. Multiple
clients can be connected to it, and you don't even need to be on the same
machine (I once connected to a GPSD running in a car in Los Angles over
CDPD... which I was ~2000 miles away).
>I don't know if it runs on Windows.
If a windows application like this doesn't exist, it really would be a good
idea to clone. The concept is similar to AGWPE's IP interface. Something
like GPSD could be thrown together with Delphi and one of the tcp/ip OCX's
quite quickly for windows.
