PK-232 MBX – OPERATING MANUAL RADIO INSTALLATION
4/91 3-6 30
NOTE:
Polarity of the FSK signals is not standardized by the radio manufacturers.
We have observed that Icom radios most often use FSK, while Kenwood ra-
dios most often use FSKR. Consult your transceiver's manual to identify the
proper polarity.
2. Connect the FSK lines from the PK-232 to your radio's FSK input in accordance with
your radio's requirements. See Figure 3-4 below.
Figure 3-4 Connector J7 FSK Connections
NOTE: When using FSK, the same power and duty cycle limits apply as cited earlier
for AFSK operation. Consult your radio's operating manual for any power or
transmit time limits.
3.3.8 Connections for an Oscilloscope
Although the PK-232 has a built-in tuning bar-graph, you may also attach an oscilloscope
for more precise tuning. Any low cost or surplus scope capable of the X-Y display of audio
signals can be used. Most station "Monitor Scopes" also have this feature.
o Connect the oscilloscope to Pins 3 (mark) and 5 (space) on rear panel connector J7.
o Connect the oscilloscope ground return to Pin 2 of J7.
o See figure 3-5 below for connections to J7.

NOTE: If your Oscilloscope cannot be AC coupled, you must place a 0.1 µF disc ca-
pacitor in series with your connections to both pin-3 and pin-5 of J7.
3.4 PK-232 Configuration Jumpers and Connections
Before operating the PK-232, you must first make sure it is correctly configured for your ra-
dio's PTT. After this has been checked you should then connect the cables you constructed
in the above steps.
3.4.1 Push-To-Talk (PTT) Configuration
Before you connect the Radio cable(s) you just made to the PK-232, consult your trans-
ceiver's manual for Push-To-Talk keying polarity. Most transmitters and transceivers made
in the last 15 years use Positive PTT keying. However some gear, especially if it contains
vacuum tubes, may use a negative PTT keying voltage.
