Certified - Unlike virtually all of
our competitors, the SignaLink USB has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15 of the FCC
Low Noise Sound Card - This provides optimum performance and
frees your computer's existing sound card for other uses.
It also greatly simplifies installation and operation, by reducing the
number of cable connections, and by providing consistent performance that is
independent of the computer's sound card.
Installation - The SignaLink USB has only one USB connection to the computer, and in most cases,
only one connection to the radio*. There are no audio cables to get
Setup and Operation - The SignaLink USB's built-in sound card
provides consistent audio levels and performance that is
completely independent of the computer's sound card. This lets us
streamline our Audio Level Setting procedure like never before. Simply
set the software "Transmit" audio controls as described in the
SignaLink manual, and then adjust the SignaLink's front panel "TX"
control for the desired RF power level. Setting of the RX Level is even easier, as this
is done completely by the SignaLink front panel "RX" control.
There are no software "Recording" controls to adjust!
Convenient Front Panel
Controls - You can now easily adjust your TX Audio, RX Audio and
Transmit Delay without having to open the SignaLink case. This lets
you optimize your Transmit Audio (RF Power), Receive Audio level ("waterfall
drive"), and Transmit "Hang Time" delay "on the
Works with ALL Radio Mic, Data,
and Accessory Ports -
The SignaLink USB works with ALL radios, and can be attached to
your radios Mic, Data, or Accessory port. This allows most users to
attach the SignaLink to the back of the radio (Data or Accessory Port) and leave
the microphone plugged in!
Sound Card Digital
& Voice Modes
- The SignaLink USB supports ALL Digital and Voice modes
that are available for sound card interfaces. This includes ALL
traditional modes such as CW, RTTY, AMTOR, and SSTV (to name a few), and ALL new modes
such as PSK-31, MT-63, and EchoLink. All standard sound card communications programs will work with the SignaLink USB.
Isolation - Unlike some interfaces
on the market, ALL SignaLink models
COMPLETELY isolate your computer from your radio. This eliminates troublesome ground loops and prevents
hum and noise from degrading the signals. The SignaLink USB provides
isolation through the use of audio transformers and a relay-based PTT keying
Transmit Audio / "Side Tone"
Output - A rear panel "Monitor" jack can be used with
headphones or powered (amplified) speakers to monitor your Transmit Audio,
or Side Tone during CW operation.
Support - If your installation requires that you attach the
SignaLink to your radio's External Speaker jack, then you can plug an
external speaker or headphones into the SignaLink's rear panel
"Aux" jack and continue to hear your RX Audio.
External Power Required - The SignaLink USB is always powered
by the computer's USB port, so external power is NEVER required..
*NOTE: Some radio's do not have the "RX Audio" signal on the Mic connector and will require a mono cable to be installed between the SignaLink USB and the radio. This is never an issue if you attach the SignaLink to your radio's Data or Accessory Port.
Every SignaLink USB is supplied with the following items:

**The Linux operating system is not officially supported by our chipset manufacturer, or Tigertronics. We will do our best to help you get your SignaLink working in Linux if you call for Tech Support (click here for some customer provided information on running the SignaLink USB in Linux), but please understand that we do not run this OS ourselves so support for it will be very limited. If you are not familiar with installing and configuring software/hardware in Linux, then we strongly suggest that you use a different OS with your SignaLink.
