VERY IMPORTANT NOTE! You are about to install
the jumper wires. The wires must be 24ga AWG or
you will damage the socket! It would be best to use the
wires that we provided for this purpose to avoid
damage.
·
Install Jumper Wires
jumper wires go, all you need to do is install them!
This is best done by gripping them close to the end with
needle-nosed pliers. When pushing the wires into the
socket, be very careful not to bend them back and forth
or they might break. If you break a wire off in the
socket, there is no way to remove it. You will have to
have a new socket installed! This should not be an
issue if you are just a little bit careful. If you plan to
change the socket configuration often for different
radios, you might prefer to use a Dip Header for
programming, rather than wires. The Dip Header is a
small terminal block that you can solder the wires onto
and then simply plug into JP-1 when it s finished. This
is by far the best method if you need to switch radios
often. The Dip Headers are available from Tigertronics
as part number SLHEAD , and from electronic
suppliers like DigiKey (P/N A103-ND) and Mouser
(P/N 544-16PT-02).
Once you have all of the jumpers installed, take a
minute to look them over. You might want to compare
your jumper settings to the sample settings shown in
the Jumper Settings
CDROM.
NOTE:
If you are using the external SPKR or
PWR input jacks on the rear of the SignaLink, then
you should NOT have any jumpers going to the
SPKR or PWR pins on JP-1.

Measure Accessory Voltage
not necessary. But, if you have wired the accessory
power from your radio and are not sure if it is adequate
to power the SignaLink, then you can easily verify the
voltage. First make sure the pc board is on an insolated

Now that you know where the
section of the SignaLink
This step is normally
surface (no metal or wire clippings under board!).
Turn on the radio and press the Power switch on the
SignaLink. The green Power led should illuminate.
Using your multimeter (volts) verify the voltage
between chassis ground and test point TP-1 near the
left rear corner of the SignaLink pc board (Figure-4).
The voltage should be at least 6.75 volts for proper
operation. If the voltage is not adequate, then you will
need to remove the Power jumper on JP-1 and power
the unit externally (see Connecting Power ).

- AUXILIARY AUDIO OUTPUT
The SignaLink has an Auxiliary Audio Output jack on the
front panel that can be used to attach an external radio
speaker or headphones for monitoring receiver audio.
Inside the SignaLink we have provided jumper JP-2 to
allow you to select when the external audio jack is active.
By default we have jumpered both positions on JP-2 which
makes the audio available all of the time. However, you can
move the jumpers to allow the jack to be active only when
the SignaLink is ON or OFF. To make the jack active when
the unit is ON, jumper pins 1 & 2. To make the jack active
when the unit is OFF, jumper pins 3 & 4. For example, if
you only install the jumper on pins 3 & 4, the audio jack
will only be active when the SignaLink is OFF. This is a
nice way to mute the speaker when you are working the
digital modes! Note that if your radio has audio on the mic
connector, you can also use the rear panel SPKR connector
for an external speaker. This jack is wired directly to the
SPKR pin on JP-1.
NOTE: Attaching or removing an external speaker while
you are using the SignaLink will change the loading on the
radio s speaker circuit. This will probably cause a change
