8-Pin Din Radio Connector (KAM HF)
8-Pin Din
Female (Looking at Holes)
Pins 1, 2, 3 and 6 must be connected to your radio.
Pin 1 - AFSK Out - white lead. This line carries the AFSK tones generated by the
KAM to the Audio Input (microphone) line of your transceiver.
Pin 2 - Ground / Shield - black and shield of 9-wire cable and shield of audio cable.
Connect the push-to-talk ground and AFSK shield to this line. With some transceivers
which do not reference PTT and audio shielding to a common ground, it may be
necessary to leave the AFSK shield (braided wire) disconnected. Note: All TNC grounds
are common.
Pin 3 - Push-To-Talk - brown lead. This line controls the PTT line in your transceiver
allowing the computer to switch the transceiver from/to transmit or receive. Connect
directly to the PTT line of the mic-jack connector.
Pin 4 - Key Out - orange lead. This line may be used to control CW keying on your
E?
transceiver.
Separate
a
small
length
of
this
lead
and
attach
a
lead
with
the
appropriate
i plug for your transceiver key jack, where you would normally connect a straight key.
Pin 5 - FSK Out- red lead. This line is for use if your transceiver provides FSK keying
for
radioteletype
operation.
Separate
a
small
length
of
this
lead
and
attach
a
lead
with
the appropriate plug for your FSK input connector on the transceiver. It will also be
necessary
to
provide
for
PTT
keying
via
the
mic
jack,
accessory
port
or
other
method
specified by your transceiver manual.
Pin
6
-
Audio
Signal-
2
conductor
audio
cable,
center
conductor
and
9-wire
cable,
purple
conductor.
Plug
this
lead
to
one
leg
of
the
Y-connector
cable
provided
in
the
KAM
accessory
bag.
Plug
the
Y-connector
cable
into
the
external
speaker
jack
of
the
transceiver.
The
remaining
female
connector
on
the
Y-connector
cable
may
be
used
for
an
external
speaker.
Do
not
use
a
headphone
output
from
the
transceiver.
If
you
use
an
accessory
or
phone
patch
output,
it
may
be
necessary
to
provide
a
padding
network
to
reduce
amplitude
of
the
signal
being
fed
to
the
KAM.
High
level
fixed
outputs
may
have
a
tendency
to
"swamp"
the
KAM
input
circuits.
Fixed
output
signals
in
excess
of
50
mV
should
be
padded.

This
pin
is
not
connected
in
the
KAM
but
the
blue
conductor
of
the
9-wire
cable
is
attached
to
this
pin.
Pin
8
-
XCD
-
yellow
lead.
This
line
may
be
used
to
connect
the
squelch
line
from
your
HF
transceiver
if
desired.
This
connection
will
not
normally
be
required,
nor
used,
unless
operating
on
a
shared
voice
channel.
