Step 5. Plug both the microphone connector and the external
speaker jack into your transceiver.
Wiring to a Data Jack
If you chose to wire your KAM’ 98 to your SSB radio’s data (ACC) jack, this is
the right place. Connections for the KAM’98 Radio Port end of the cable assem
-
bly will be the same as if you were making up a cable to connect to the MIC and
Speaker jacks of the radio. Completing the cabling end to attach to the radio’s
data jack will, of course, be different.
You’ll have to determine which pins in the data jack match up with which pins in
the KAM’98 radio port. You’ll need to make four connections:
1. data in, i.e. data coming from the KAM’98 to the jack,
2. data out, i.e. data coming from the radio to the KAM’98 (audio),
3. push-to-talk, the line that will key your radio (also called standby),
4. ground.
In addition, you’ll need to obtain the proper connector for the data jack. Most ra-
dios use a 7 or 8-pin DIN, available from Radio Shack.
Assembly: Follow the guidelines in the previous section for wiring the KAM’98
DB-9 Radio Port side of your DATA JACK cabling assembly. Then wire up the
data jack end of the cable, with needs as determined by the radio manual and
matching up names (functions) with the KAM’98’s signals listed above.
Adjusting Receive Volume and Squelch Control of Your
Transceiver
Both non-packet and packet modes should function properly when your trans
-
ceiver is adjusted to a comfortable listening level, and most signals are copyable
by the KAM’98 even at levels you may not hear. Weak signals, however, may not
be read if your radio has a receive signal squelch control and its level is set too
high.
Follow the procedures below if you are going to use squelch operation, usually -
but not always - reserved for FM packet operations. If you don’t wish to listen to
traffic but want to copy all signals possible, leave the squelch completely open
but reduce audio volume, or wire receive audio via the radio data jack..
