Click the Audio tab.
·
Under Sound Playback and Sound Recording ,
select your computer s soundcard as the Default
Device . The exact name of your computer s
soundcard will vary, but unless you have more than
one sound card installed, you will only see the
computer s sound card and the SignaLink s sound
card listed ( USB Audio Codec ). Click the OK
button and close the Control Panel.
·
Your computer is now configured to send all
system sounds to your computer s sound card and
speakers (see the important note below).
NOTE: If your computer is used only for Amateur Radio
Operation, then you might want to select the SignaLink
USB ( USB Audio Codec ) as your default sound card.
This will force all programs (communications and
otherwise) to always use the SignaLink USB. This can also
be done if you are using an old sound card program that
won t let you select the sound card that you want to use. If
you do select the SignaLink USB s built-in sound card as
the default card, then we suggest that you disable all
Windows system sounds.

- SETTING THE AUDIO LEVELS -

The SignaLink USB s built-in sound card provides the same
consistent audio levels no matter what computer you are
using, so the software audio level setting procedure has been
greatly simplified. Before you operate your SignaLink USB
on the air, you will need to adjust the PLAYBACK software
volume controls, and the SignaLink s TX and RX level
controls. Note that the SignaLink USB does NOT use
software RECORDING controls ( waterfall drive , etc.), so
you will not need to worry about adjusting those.
Adjustment of the Receive Audio is done completely by the
SignaLink s RX level control.
While most levels are not too critical, incorrect adjustment
of any of these levels can cause poor performance or
unreliable operation. This procedure tells you how the
levels should be set.

Preliminary Setup

·
Before you can adjust the audio levels, the SignaLink
USB must be connected to the computer and radio.
Both the SignaLink USB and the radio should be
powered ON and a communications program that you
have selected should already be installed on your
computer. Note that

continuous "Tune" mode.
DigiPan is ideal for making these adjustments.

jack, then set your radio to USB mode (note that you
can change this later if the mode you want to run
requires LSB).

If the SignaLink USB is connected to a Data or
Accessory Port, then you will need to set your radio to
the appropriate mode for this type of connection. USB
will work on most radios, but you may need to select a
special mode such as Data , User , or D-USB . If
you are not sure which mode to use, then consult your
radio manual.

Set the radio s Mic Gain control to 50%. Note that if
the SignaLink is connected to a Data or Accessory Port,

Set your radio s Forward Power control to provide
maximum power (this will be adjusted later to bring the
power down to a suitable level).
