PK-232 MBX – OPERATING MANUAL RADIO INSTALLATION
4/91 3-7 31
The PK-232 is configured for positive PTT at the factory so it will operate with most equip-
ment without changes. However, if necessary, you can change the polarity of the PTT con-
figuration on either or both RADIO 1 and RADIO 2 ports. Follow these steps:
o Remove four screws from the sides and two screws from the rear of the PK-232
chassis cover and lift off the cover.
o Locate Jumper posts JMP2 and JMP3 which are near the RADIO 1/RADIO 2 switch
SW2.
o JMP2 configures the RADIO 1 port and JMP3 configures RADIO 2.
o When the shorting jumper is towards the front, the port is configured for Positive
(+) PTT. When the shorting jumper is towards the rear, the port is configured for
Negative (–) PTT.
NOTE: This is especially useful if you want to configure one radio port for positive
PTT and the other for negative PTT.
Replace the cover and six screws when you are finished configuring the polarity of the PK-
232 PTT circuit.
3.4.2 PK-232 Connections
Remove power from the PK-232, 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-232 and your transceiver(s).
IMPORTANT NOTE
MAKE SURE THAT THE RADIO CABLES EXIT "DOWNWARD" FROM THE TWO RADIO
JACKS ON THE REAR PANEL. ALTHOUGH NO DAMAGE WILL OCCUR FROM REVERSE
CONNECTION, YOUR PK-232 AND RADIO WILL NOT OPERATE CORRECTLY!
If you wired cables for CW keying, Direct FSK or an Oscilloscope 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. If you are connecting
an FM transceiver to one of the radio ports of the PK-232, then we recommend that you ad-
just 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 moni-
tor 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.
