Your Transceiver’s Microphone Connections to Your KAM’98.
If you use the microphone on your transceiver, you may wish to makes notes of
the following connections, which you will use for wiring your assembly:
•
identify and make a note of the microphone input (which will be wired to
pin 1, transmit audio on the KAM’98’s DB-9 “Radio” port),
•
identify and make a note of the PTT or STBY connection (which will be
wired to pin 3, Push-to-Talk on the KAM’98’s DB-9 “Radio” port),
•
for base or mobile (but not hand-held) transceivers, identify and make a
note of the ground connection (which, optionally, may be wired to pin 9,
one of the ground pins on the KAM’98’s DB-9 “Radio” port, or left
unconnected).
Your Transceiver’s Speaker Jack Connections to Your KAM’98
For the speaker jack on your transceiver, make a note of the following connec-
tions, which you will use for wiring your assembly:
• identify and make a note of the connector to the tip of your external
speaker plug (which will be wired to pin 5, receive audio on the
KAM’98’s DB-9 “Radio” port),
• identify and make a note of the connector to the sleeve of your external
speaker plug (which will be wired to pin 6, one of the ground pins on the
KAM’98’s DB-9 “Radio” port).
Constructing the Cable Assembly
Important: As shown in the wiring side diagram immediately below, the pins in
the KAM’98’s female DB-9 “Radio” connector are numbered from the upper
right (pin 1) to the lower left (pin 9). As you connect wires to pins on the DB-9
connector on your cable, you need to be sure to connect to the correct pins.

Similarly, when working with a typical 8-pin Mic connector where you know the
pin numbers of pins, you need to consider which way you are looking at the con
-
nector (looking at pins/holes or looking at the wiring side, where the wires are
actually connected).
