<DIV><FONT size=2 face=Arial>Gday,</FONT></DIV>
<DIV><FONT size=2 face=Arial>I also used an OPENTRACKER OT1plus in my 4WD in
VK6</FONT></DIV>
<DIV><FONT size=2 face=Arial>on 30m HF on 300Baud.</FONT></DIV>
<DIV><FONT size=2 face=Arial>I have installed a switch to switch between 300baud
and 1200baud (HF/VHF)</FONT></DIV>
<DIV><FONT size=2 face=Arial>Both modes work great and on top the OT1plus can
transmit telemetry data ( so I used that feature to transmit temperature of
engine and barometric altitude, etc...)</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>However for sucessful tracking on 300baud AFSK a
good network of receiving GATEways in mandatory. Unfortunately most IGATES on HF
only use old TNCs,</FONT></DIV>
<DIV><FONT size=2 face=Arial>which have very narrow bandpass. So your mobile has
to meet very acurate frequency setting (30Hz), which is unrealistic even with
modern trx in outback temp range.</FONT></DIV>
<DIV><FONT size=2 face=Arial>As far as I know, only the Igates in VK6 and VK8
have new DSP-technology in use, with 800Hz (!!) capturing :</FONT></DIV>
<DIV>>></DIV>
<DIV>300 baud AFSK (old HF-Packet standard) with new developed multi-detector:
The DSP automatically processes a frequency range of +- 400 Hz looking for 300
bd transmissions and receives all detected signals in PARALLEL. No exact tuning
by the user is necessary any more, but always perfect reception! Very important
feature for automatically operating HF APRS gateways.</DIV>
<DIV>>></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>So in recent years I prefer to use a SCS DSP-TNC
for my HF-APRS mobile activities. Here is why:</FONT></DIV>
<DIV><FONT size=2 face=Arial>it has a full stand alone DSP-TNC/ Tracker for
9600/1200/300baud and Robust Packet mode,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>it can display received positions of other
mobile stations on GPS-screen,</FONT></DIV>
<DIV><FONT size=2 face=Arial>(helpful to see other 4WDs driving in the
outback)</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>it can be used as a Cross-Mode--CrossBand
Digipeater.</FONT></DIV>
<DIV><FONT size=2 face=Arial>( nice to use ur VHF handheld VX-8 or THD7 on
hiking, while using ur parking 4WD as digipeater to transvert ur sigs from vhf
to hf 30m.</FONT></DIV>
<DIV><FONT size=2 face=Arial>just setup ur FT100,FT857 or IC706,IC7000 for SPLIT
operation 145rx/10tx)</FONT></DIV>
