Troubleshooting - Tigertronics SignaLink USB Installation & Operation Manual

If you do not find your problem listed here, or if you are
unable to resolve the problem, then please refer to the
Technical Support section of this manual for instructions on
contacting our Technical Support Staff.
Radio doesn t transmit AND the SignaLink USB's PTT
LED is OFF - Check the following:
·
Verify that the SignaLink USB s PWR LED is ON. If
it is not, then check your USB cable connection to the
computer and the SignaLink.
·
Verify that your communications program is configured
to use the SignaLink USB s built-in sound card. The
program should have USB Audio CODEC selected as
the sound card for both Transmit and Receive.
·
Verify that the PLAYBACK volume controls for the
SignaLink USB are set according to the Setting The
Audio Levels procedure. If they are too low, then the
SignaLink USB will NOT transmit.
Radio doesn t transmit even though the SignaLink's
PTT LED is ON - If the SignaLink USB's PTT LED turns
ON but the radio doesn't switch to transmit, then you have
most likely jumpered the PTT signal incorrectly on JP-1 (go
back and double-check ALL jumpers). If the SignaLink is
attached to your radio s Data or Accessory Port, then
another possible cause is that your radio isn t configured
properly to use that port. Consult your radio manual and
verify that your radio is in the correct Mode (Digital USB,
etc.).
Radio transmits but there is no power output, or it is too
low
The SignaLink USB can provide more than enough
Transmit Audio to drive any radio to full power. If you
have set the TX level control to maximum and still cannot
get enough power, then check the following:
·
If you are using a CAT interface to control your radio,
then you need to disable "PTT by CAT Control" (or
similar option) in your communications software, so
that the SignaLink can key the radio. This is necessary
because some radio's will only look for Transmit Audio
on the Mic jack if the radio is switched into Transmit
by the CAT interface. Note that this is a design issue
with the radio and has absolutely nothing to do with the
SignaLink.
·
Verify that your radio s Forward Power (sometimes
called RF Power or Carrier Power ) control is set to
maximum.
·
If the SignaLink is attached to your radio s Mic jack,
then try turning up your radio s Mic Gain control.

radio s speech processor/compressor is turned OFF. Your
radio s Forward Power control (sometimes called RF

you have lowered this control to decrease your transmit

correctly, then try turning the radio s Mic, Data or Accy
Port gain and see if that improves the quality of your signal
(Data/Accy Port gain is usually a radio menu setting). If
this has no effect, then you may have the software PlayBack
volume controls, or the SignaLink USB s TX level control
set to high. See the Setting The Audio Levels procedure
to correct this.
The SignaLink s TX control is near minimum but the
Radio s transmit power is too high
because the radio s Mic, Data or Accy Port gain control is
set too high. If the SignaLink is attached to the Mic jack,
then try turning the radio s Mic Gain control down ( this
may also affect Data/Accy Ports on some radios). If the
SignaLink is attached to a Data or Accy Port, then your
radio should have a menu setting or trimmer to adjust the
gain. Note that some radios call the Data or Accy Port gain
control Packet Input Level or Packet Gain . Contact
Tech Support if you are unable to resolve this problem.
