Adjusting the KPC-9612 for receive is fairly easy. Connect a voltmeter (analog preferred) to pin 8
of the DB-15 connector (RX S/N) or test point J on the PC board and pin 10 (ground) of the DB-
15. Have another 9600 baud station transmit long packet bursts, and adjust R33 for a peak read-
ing on your Voltmeter. (Maximum reading is approximately 3 VDC.) This is the signal quality line in-
dicating how well the 9600 baud modem is decoding the received signal. This indication is more
accurate than using the eye-pattern method (used with the G3RUH modems). (See the Calibra-
tion/Equalization section later in this manual for more information.)
Operating Packet
After you have connected the KPC-9612 to the radio(s), you will begin receiving packets. As pack-
ets are received, the KPC-9612 sends them to your terminal for display. A typical received packet
might look like this:
W0XI>WK5M/1<<I00>>:
Good morning.
The first line is the header line which displays the callsigns of the stations talking. The
/1
indicates
that this packet was received on the 1200 baud port. A packet received on the 9600 baud port
would show
/2
at the end of the header line. The following line(s} are the actual transmitted mes-
sage. You may see the RCV LED light at times, indicating that a signal is being received, although
nothing displays on your screen. This is normal and is the result of the many monitoring com-
mands that are discussed in detail in the Reference Manual.
As you monitor, you will begin to learn which stations are in your area and will then want to try to
connect to one of them. To instruct your KPC-9612 to connect, disconnect or to change any of the
operating pararneters, you must be in the COMMAND Mode. To send data from your keyboard over
the radio, you will need to be in the CONVERS Mode. The KPC-9612 automatically switches to the
CONVERS Mode when you connect to someone and returns to the COMMAND Mode when a dis-
connect occurs. If you are in the CONVERS Mode and want to force your KPC-9612 back to the
COMMAND Mode, type CONTROL-C. Remember, you must be in the COMMAND Mode in order to
give instructions to your KPC-9612.
Connecting at 1200 baud
Suppose you want to connect to WD0EMR, a station you monitored on port 1 (1200 baud). First,
be sure you have the KPC-9612 in the Command Mode. To do this, type a CONTROL-C and press
return. You should see a command prompt (
cmd:
). Since this station was monitored on 1200
baud, you must make sure your KPC-9612 is ready to transmit packet at 1200 baud. Type the ver-
tical bar (
|
) and the letter "
a
". This will set the KPC-9612 to transmit on port 1. Now use the CON-
NECT command to start the connection. To connect to WD0EMR, simply type
CONNECT WD0EMR
and press return, just as you did in the sample connect to your mailbox.
In some cases you may need to use a relay station, called a digipeater, to contact another station.
This is similar to using a voice repeater when the station you want to talk to is out of simplex
range. To connect to a station using digipeaters, you still use the CONNECT command, but you
must also specify the callsigns (or aliases) of the digipeaters that must be used. For instance, if
you need to use two digipeaters with callsigns of W0XI and KO0W in order to connect to KA5ZTX,
you enter the command as:
CONNECT KA5ZTX VIA W0XI,KO0W
