<DIV><FONT size=2 face=Arial>Andrew,</FONT></DIV>
<DIV><FONT size=2
face=Arial>
thanks for getting back to me.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The FMI = Fleet Management Interface, was a
function of some Garmin GPS systems (1990's) that allowed the boss of say a
courier service to databurst packet info to their employees - employees out in
their veh can respond back. It allows the Garmin 350 to display callsign
info as a Point Of Interest on the GPS, it needs the special cable (translator)
from Argent Data Systems to do this. This also allows you to send and receive
messages like you would for texting SMS or as you would on APRS.fi maps. The GPS
is NMEA 0138 input/output format & the cable/TNC recognises this.To bring up
the "Despatch" menu on the GPS, all you need do is plug in the translator cable
& it appears (can reset the GPS back to normal use if
required).</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The OT3 (TNC) has test functions built into it to
adjust your audio level, test tones can be produced to adjust audio, check the
TX PTT & some other functions of the TNC, I can get the functions to work
fine - but with no audio tones for testing the TX. This should be TX'd over RF
& heard by another RXCVR - I've tried. This is all done from the
PC program. I know the GPS and translator cable work fo TXing a msg
as I can send commands to the TNC (OT3) and I get an answer back after it
has interrogated it, I can even send a msg to my VX8GR & the RF signal is
picked up at VK2RCC-1 & I can see myself on APRS.fi maps.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I plug a USB cable into the OT3 to
interrogate/program it.The GPS & radio are still connected when this occurs,
although I can and have removed them previously for programming - no
effect. I have adjusted the configuration as suggested from APRS .net
website for OT3's & even from the guy that makes these units (Scott Miller
in USA). - NO JOY!</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The TNC has several modes, tracker being one of
them. I'm using it as "Garmin" on the A port.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>You are quite correct - they do work somewhere
else, just not for me. I am unsure if it is hardware or configurations. I have
been told it is a matter of adjusting the audio level to get the TNC to work
correctly. That may be the case but I don't see how if it is already TXing some
msg's from the GPS, but NOT RXing it. My understanding is the audio setings are
for the TX to allow correct deviation configuaration. I thinkthe problem lies in
GPS / cable / TNC. The FT8800R is correctly setup for packet.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I thought somebody out there may have experienced
the same problem, I'm the only APRS user around these parts so bit hard to
find help.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Sorry for being long winded - hope this clarifies
things.</FONT></DIV>

350 & OT3m</DIV>
<DIV><BR></DIV>
<DIV><FONT size=2 face=Arial>Good morning, </FONT></DIV>
<DIV><FONT size=2
face=Arial>
I'm after some help with my APRS mobile set up. I've got a FT8800R, Garmin
Nuvi 350 & Argent Data System OT 3 TNC. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The OT3 is operating the radio correctly. My
problem is the garmin 350 is not displaying POI, receiving messages or
sending any messages from the FMI (GPS unit). I have the correct Garmin
cable from Argent Data Systems. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> I have tried the configuration program
for the Open Tracker 3 & cant get any of the test tones to work (I cant
hear them form my speaker or another radio).Can anyone shed some light - I'm
getting frustrated with it.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Cheers,</FONT></DIV>
