Yes, this works fine in my car.  I do this with a Deluo GPS unit that feeds
a TinyTrak to a radio that is the beacon.  The GPS has unidirectional data,
so multiple devices can be fed.  In my car, the other split goes to my
Laptop to feed mapping/tracking and also can attach to a second TNC.  Not
sure you can use the same radio for both, though.

I need some advice on building a multi-mode APRS tracker. 

The attached schematic illustrates what I'm trying to do.  In case the list
manager strips attachments, it shows that I want to build a beacon-style
tracker that will simultaneously feed the GPS position and APRS network
traffic to a laptop PC.  The GPS data would be used for onboard vehicle
navigation and the APRS feed is to monitor the location of other stations. 

I'm using a dedicated radio (Yaesu FT-1500) for this purpose.  The FT-1500
has a 6-pin DIN port on the back specifically for TNC communications. 

My original design concept was to attach a Byonics TinyTrak3+
<http://www.byonics.com/tinytrak/tt3plus.php>  to the microphone connector
of the radio for the beacon.  An RS-232 splitter
<http://www.sfcable.com/store/d920-yy.html>  would send the GPS
<http://www.deluoelectronics.com/customer/product.php?productid=99>  data to
the TinyTrak and to the laptop simultaneously.  An Elcom USB MicroTNT
<http://www.elcom.gr/>  in KISS / listen mode attached to the radio's data
port would send all of the APRS data to the laptop.  Will this work?

Alternatively, I just read a writeup about the PacComm
<http://www.paccomm.com/>  dual-port PicoPacket...

It looks like the PicoPacket will do all of the above, w/o the need for a
second TNC or strange cabling, yes?


Thanks!
