For special signals requiring un-filtered
"discriminator" audio, you will need to move the
"SPKR" jumper to pin #4 (9600 baud output). Note
that some newer radios do NOT provide this output, so
this may not apply to your radio.
**IC-706MKIIG - If you are using the Data Port on
this radio, then you must set menu #29 "9600
Mode" to 1200.
***IC-746PRO / IC-7000 - Some users have reported
that this radio has a very sensitive Data Port, making
power adjustments with the SignaLink USB's TX knob
somewhat touchy.
****Mic audio is NOT muted on this radio.
## IC-910H: You will need to connect the
SignaLink to the “Main” data port connection on
this radio (not the “Sub” port)
***NOTE: The SignaLink USB's TX control is "touchy", making it difficult to control my RF power - This is most likely because the radio’s Mic,
Data or Accy Port gain control is set too high, but before continuing, please be sure that you have NOT installed special jumper JP3 inside the SignaLink.
This jumper is rarely needed, and will normally cause the SignaLink to provide too much audio to the radio making adjustment of the TX knob difficult.
If the SignaLink is attached to your radio's Mic jack, then you can resolve this issue by turning the radio’s Mic Gain control down. If the SignaLink is
attached to the radio's Data or Accy Port, then your radio likely has a menu setting or trimmer to adjust the gain. This gain adjustment is often called “Packet
Input Level” or “Packet Gain”, but may have another name, so check your radio manual carefully. Note that the radio's Mic Gain control on some older
radios may also affect the Data/Accy Port (TS-440 for example), so you should check this as well.
If the above solutions don't help, then we suggest that you install Special Jumper JP4 inside the SignaLink and LOWER the software "Wave" control for the
SignaLink's sound card. Note that the "wave" control is the "Applications" volume control if you are using Windows Vista, or Windows 7. The "Wave"
control can be lowered to just above the point where the SignaLink's PTT LED turns OFF, so as to provide minimal TX Audio to the radio while insuring
that the SignaLink's PTT circuit functions correctly. We recommend finding this threshold while transmitting a steady test tone, and with the SignaLink's
Delay knob set to minimum.
***NOTE: If you are using an ICOM IC-7000, IC-746PRO, or Yaesu FT-450, please note that some customers have reported that these radios have
unusually sensitive Data Ports, which can make adjustment of the SignaLink's TX knob somewhat difficult. If this is the case with your radio (and the
solutions listed above don't work), then you can easily resolve the issue by replacing the SignaLink's "Mic" jumper wire with a standard 1/4 watt size
resistor. Both a 47K and 100K resistor have been reported by several customers to allow easy adjustment of the power level. Please note that you **DO
NOT** solder this resistor. It simply plugs into the JP1 socket in place of the MIC jumper wire. Be sure that you use a 1/4 watt size resistor, so that you
do not damage the SignaLink's socket!

24-pin DIN Accessory Port Connector - Tigertronics
does not manufacture a cable for the ICOM 24-pin
Accessory Port connector, but you can easily build one
using our un-terminated radio cable (p/n
SLCABNC). To build your cable, simply wire it
straight-through for pin numbers 1-8 (Pin #1 to Pin #1,
Pin #2 to Pin #2, etc.). Note that your cable MUST be
wired straight-through or the jumper settings shown
below will NOT work, and you might DAMAGE
YOUR RADIO OR THE SIGNALINK!
Pins marked as "N/C" are not used by the SignaLink, but
might be connected internally inside the radio.
