3.4.2 PK-900 Connections
Remove power from the PK-900, your transceiver and all accessories
before making any connections.
Connect the radio cable(s) you constructed in section 3.3.5 between a
Radio port on the PK-900 and your transceiver(s).
If you wired cables for CW keying or Direct FSK then connect these to
the appropriate point on your equipment.
3.5 Transceiver Adjustments
This section is split into separate procedures for FM and SSB radios.
You may adjust either port at any time without affecting the other.
3.5.1 FM Transceiver Final Adjustments
1. Turn on your computer and PK-900 and start your terminal
program.
2. Connect the radio to a dummy load. Be prepared to monitor your
transmissions with another nearby radio such as a handheld
transceiver.
3. Verify that your PK-900 and FM radio are connected as shown in
Figure 3-5 below.

4. If you are using an AEA program such as PC-PAKRATT II 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-900's tone generator from "Mark" (the lower pitched
tone) to "Space" (the higher pitched tone). The PK-900
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."
