<br>
I've been trying to set up my APRS equipment and make sure everything
works before I put it in the car. The problem I have is that the TNC
will not key up the radio in GPS mode. <br>
<br>
I have the following hardware:<br>
<br>
Garmin GPS V Deluxe<br>
Kantronics KPC 3+<br>
Kenwood TH-79A dual band HT<br>
<br>
The GPS is working fine because I connected it to my pc and could see
the data displayed in hyperterminal every 2 seconds. The cable that
came with the GPS has a 9-pin female connector, and the TNC has a
25-pin female connector. I used a 25-pin male to 9-pin female adapter,
and a 9-pin male to male gender changer to get the GPS and TNC
connected. <br>
<br>
I configured the TNC exactly the same as the example shown in the
manual for GPS use. The baud rate is set to 4800 for both the GPS and
TNC. The GPS is set to output NMEA type data. The TNC's receive light
comes on as it normally would when a signal is heard. The TNC will key
up the radio in TERMINAL mode, but not in GPS mode. I used the
following parameters to set up my TNC:<br>
<br>
GPSINIT $PGRMO,GPGGA,1
<br>
GPSHEAD 1 $GPGGA
<br>
LTP 1 GPS via DIGI
<br>
BLT 1 EVERY 00:01:00
<br>
ABAUD 4800
<br>
INTFACE GPS
<br>
<br>
<br>
Does anyone have any suggestions on how to get this going?<br>
<br>
Thank you<br>
