TROUBLESHOOTING GUIDE

INSTALLATION:  Did you use PKUNZIP -d to get all the following subdirectories?
                   SYSTEM    (must have INITTAPR.TNC and RESTORE.TNC)
                   MAPS      (Must have at least WORLD or USA map)
                   BAKS
                   LOGS
                   HSTS
                   README
OPERATION:  Is your receiver volume set high enough so that the DCD lamp
on the TNC lights whenever there is received data? 

RECEPTION:  Verify reception by observing the DCD lamp whenever data is heard.
If the data is strong enough, and ERROR-FREE, then it will be displayed
on the bottom line of the display.  Verify proper decoding by observing
the L and P lists for collection of packets from other stations.

TRANSMISSION:  Hit the OPS-PING command to force your system to transmit.
Within a second or so, and after the channel is clear, your transmitter 
should key up for about a second.

VERIFY COMMS BETEEN YOUR PC AND TNC:  Do an OPS-COMM-TNC to verify proper
serial interface to your TNC.  Hit ENTER and verify that you see the TNC 
cmd: prompt.  If OK, then your serial PORT and TNC are communicating.  Hit
ESC to return to the program.  Do NOT type any commands to the cmd: prompt
because there are 100's of commands, each one of which can screw up the TNC!
APRS initializes your TNC using the commands in APRS\SYSTEM\IinitTAPR.TNC
or InitAEA.TNC.

VERIFY PROPER DATA FORMATS:  Using the OPS-COMM-TNC command, observe  
received packets.  They should appear in approximately the following format:

   W3XYZ>APRS,WIDE:@123456/.......etc

The WIDE represents a list of digipeaters, but nothing else should be in the
received packet header other than the FROM call, APRS, digipeaters, and then
the COLON: that begins the data.  The data must be on the same line as the
header.  If not, set HEADERLINE OFF.  If any other stuff is being inserted 
into the monitored packet, use your TNC manual to turn off all other monitoring
features.  If your TNC needs any special set up parameters, add them to the
InitTAPR or InitAEA.TNC files.


BAD COMMS BETWEEN PC AND TNC:  If there appears to be no data going to or from
the TNC and there is no cmd: prompt in the OPS-COMM-TNC mode, then stay in the
OPS-COMM-TNC mode and do a power cycle on the TNC power.  You should get a 
RESET of the TNC and see several lines of initialization text.  If you do, 
then ESC back to the program and do an alt-SETUP-TNC command to have the 
program initialize the TNC parameters.  If there is still no data, then check 
your serial port cables.

PARITY:  The MFJ and other standard TAPR TNC's need PARITY 0, but the 
Kantronics products need PARITY 4.

AEA PRODUCTS:  Since some of the AEA setup commands are different than the 
standard, you must tell APRS that you are using an AEA so that it will use
the commands in InitAEA.TNC.  Also, the AEA monitor format is different.
In some early models of the PK-12, the monitor function was not correct.
If you add the command BBSMSGS ON to the InitAEA.TNC file, then the AEA will
emulate the standard TAPR monitoring function and work properly.
