Tigertronics SignaLink USB Installation And Operation Manual page 13

· The Windows Playback Application control can be
adjusted higher than the recommended 50% level. This will
increase the Transmit Audio to the radio which will increase
the RF power output.
· See the Special Jumpers section of this manual and
enable jumper JP3. This will dramatically increase the
SignaLink s Transmit Audio level. Note that this is NOT
needed for most radios, so you really need to be sure that
everything else has been checked before doing this.
·
If the SignaLink is attached to a Kenwood 13-pin
Accessory Port, then you may have set the PTT jumper
incorrectly. Double-check the document that was supplied
with your radio cable or our online support information to
see what configuration your radio requires.
Radio switches to transmit but the RF power level is too
high, or difficult to control with the SignaLink's TX
knob.
NOTE: Be sure that the SignaLink's TX knob is actually
affecting the RF output level before proceeding. If it has no
affect whatsoever, then skip to the next problem.
· Verify that special jumper JP3 is NOT enabled inside the
SignaLink.
· Verify that the Windows Playback Application control
for the SignaLink's USB's sound card is set at 50%.
· Verify that the radio s speech processor/compressor is
turned OFF.
· If the SignaLink is attached to your radio's Mic jack, then
lower the radio's Mic gain control. Too much Mic gain can
make adjustment of the SignaLink's TX knob touchy.
· If the SignaLink is attached to your radio's Data or Accy
Port, then the radio may have a Transmit Input Level (or
similar) menu setting that you can lower. Note that the Mic
Gain control may also affect the Data/Accy Port on some
radios, so it is also worth checking.
·
Some radios such as the IC-746PRO, IC-7000 and
FT-450D have a very sensitive Data Port and require
different settings to allow smooth control of the RF power
level. For these radios we suggest that you do ALL of the
following:
1 Install special jumper JP4 inside the SignaLink (see the
Special Jumpers section of this manual).
2 Set your radio's RF Power setting 10 watts higher than
the desired power level. For example, if you want to run 10
watts for PSK31, then set the radio for 20 watts.
3 With your communication program in Transmit and the
SignaLink's DLY knob OFF (fully counter-clockwise), lower
the Windows Playback
SignaLink's sound card all the way down to 0%.
Application control for the
SignaLink's PTT LED should turn OFF. Next, very slowly
adjust the Application control back up until PTT just turns
ON. Note this threshold point and then adjust the
Application control 15-20% higher. The goal is to have the
Application control set as low as possible while maintaining
reliable PTT activation. You may want to repeat this step a
few times to be sure you have correctly identified the
threshold point. Note that if you set the Application control
too low, PTT will be intermittent or not function at all.
Radio switches to transmit and puts out power, but the
SignaLink's TX knob has no affect on the power level -
This is virtually always because the radio is in an FSK mode
instead of AFSK. Please see the Radio Setup section of
this manual for help selecting your radio's AFSK mode.
Transmit signal is wide or distorted
always the result of over-driving your radio.
common cause of this problem is adjusting your RF Power
output with the radio's RF Power control instead of the
SignaLink's TX knob.

difficult to control with the SignaLink's TX knob above
and go through the steps listed there.
I can't seem to receive. Waterfall or spectrum is blank or
dark (Receive Audio is NOT present).
· Confirm that the SignaLink USB is powered ON and set
the SignaLink's RX Knob to 100% (you'll need to readjust
this later once the problem has been resolved).
· Confirm that your radio's squelch is open (noise should be
heard in the speaker even with no signal present).
· If the SignaLink is connected to the radio's Mic jack, then
set the radio's Volume control to 50% (you may need to
adjust this later once the problem has been resolved).
· Verify that your communication program is configured to
use the SignaLink's Speakers - USB Audio Codec and
Line
for both Transmit and Receive.
· Verify that the Window's Recording level slider for the
SignaLink's Line
set properly and NOT muted. See the Setting The Audio
Levels section of this manual for details.
· The radio's Receive Audio signal may not be getting to the
SignaLink.
SignaLink and Connecting the Radio sections in this
manual to check this. Pay careful attention to whether or not
the supplied audio cable needs to be connected, or if you
need to install the SPK jumper wire inside the SignaLink, or
enable the SPKR jumper on the jumper module.
