PK-232 MBX – OPERATING MANUAL PACKET-RADIO
4/91 4-5 40
70 cm (440 MHz) band: 440.975 MHz, 441.000 MHz, 441.050 MHz, 441.025 MHz,
441.075 MHz
You know you've found a Packet channel when you hear the characteristic
"Braaaaaap" sound of packet transmissions.
5. Once you've found an active Packet channel, you must make sure you have enough
receive audio (volume) from your transceiver to light the DCD LED on the PK-232
when a packet is being received. If the DCD LED does not light when packets are
received, you must either increase the audio level from your transceiver, or rotate
the PK-232's front panel THRESHOLD control CLOCKWISE. The DCD LED must light
for the PK-232 to be able to receive packets.
You must also make sure that the DCD LED goes out when no Packet signals are
present on the channel. If the DCD LED does not go out when the channel is clear,
make sure the Squelch control on your transceiver is set high enough to silence the
speaker. If your Squelch is functioning, then you must either rotate the PK-232's
front panel THRESHOLD control Counter-Clockwise until the DCD LED goes out
when no signals are present, or decrease the audio level. When the channel is qui-
et, the DCD LED must be OFF.
If the DCD LED stays on when the Packet channel is quiet, your PK-232 will never
send packets to other stations.
4.3.1 What You Should See
If all is operating properly, you should see some packets on your screen. Some typical
packets you might "Monitor" are shown below:
N7ALW*>WA7GCI [C]
WA7GCI*>N7ALW (UA)
K6RFK>N7ALW*>N7GMF:
Goodnight John, its been nice talking to you.
N7ALW*>WA7GCI:
Hi Bob, how are you this evening?
KD7NM*>MAIL:
Mail for: K6RFK N7ML
N7HWD-8*>ID:
NET/ROM 1.3 (SEA)
SEA*>N7ML:
SEA:N7HWD-8> Connected to #SEA:N7HWD-7
K6RFK>N7ALW*>N7GMF [D]
N7GMF>N7ALW*>K6RFK (UA)
NOTE: You will probably see data (packets) on the tuning bar-graph which do not
print on the screen. This is normal and is a function of the MONITOR and the
MPROTO commands.
