3.5 Transceiver Adjustments
This section is split into separate procedures for FM and SSB radios.
If you are connecting an FM transceiver to one of the radio ports of
the PK-232, then we recommend that you adjust this radio first. This
will establish the AFSK level from the PK-232. If the only radio you
will be connecting is an HF SSB transceiver, then skip the FM section
and proceed directly to the HF SSB Adjustment section.
3.5.1 FM Transceiver Final Adjustments
1. Turn on your computer and PK-232 and start your terminal program.
2. Connect the radio to a dummy load such as the AEA DL-1500. Be
prepared to monitor your transmissions with another nearby radio
such as a handheld transceiver.
3. Verify that your PK-232 and FM radio are connected as shown in
Figure 3-6 below.

4. If you are using a Timewave or AEA program such as PC-PAKRATT II,
COM-PAKRATT or MACRATT, you must enter the Dumb Terminal mode to
access the CALIBRATE Mode as described below.
5. Enter the Calibrate mode by typing: "CAL <Enter>."
NOTE: In the Calibrate mode only, the "K" key toggles the
transmitter PTT line on and off. The "SPACE BAR" toggles
the PK-232's tone generator from "Mark" (the lower pitched
tone) to "Space" (the higher pitched tone). The PK-232 has
a transmit watchdog timer circuit that unkeys your
transmitter automatically after sixty (60) seconds. As you
perform the following adjustments, unkey periodically, then
rekey the transmitter by typing "K."
6. Press the "K" key on the keyboard to key the transmitter. You
should hear a continuous tone in the monitor receiver.
7. Tap the space bar several times until the higher pitched of the
two tones ("space") is heard.
9. With the PK-232 keying the transmitter and sending the higher of
the two tones, adjust the transmit audio level as follows:
4/91 3-9
