Adjust the PK-232's front panel THRESHOLD control so that the
DCD LED lights when a properly tuned packet is being received.
You must also make certain that the DCD LED goes out when no
packet signals are present on the frequency.
After you have a packet station tuned in, you should start seeing
HF packet stations on your display.
4.7.5 Transmitter Adjustments
Make sure your PK-232 is adjusted for your SSB transmitter as
described in section 3.5 and 3.5.2 of this manual before transmitting.
These are very critical adjustments. If your PK-232's AFSK level and
transmitter microphone gain are not adjusted properly, other stations
will not be able to copy your packets. Check your plate or collector
current or the power output of your rig before going on the air.
