Once again Tigertronics sets the pace in digital operating! The SignaLink^TM USB sound card - radio interface combines the legendary performance of our original SignaLink^TM with a built-in low-noise USB Sound Card, delivering optimum performance while eliminating the need to attach to your computer's existing sound card. Convenient front panel controls and simplified installation make this one of the most user-friendly interfaces on the market, continuing to show that the Tigertronics SignaLink is truly the "Ultimate sound card interface"!

Virtually ALL sound card Digital and voice modes are supported by the SignaLink^TM USB. This includes today's hottest modes like FT8, FT4, JS8CALL, VarAC, VARA HF, VARA FM (Wide and Narrow), MSK144, PSK31, JT65, WSPR, FREEDV and EchoLink, as well as traditional modes such as RTTY, SSTV and CW. Performance on all modes has been optimized by the use of special low-noise parts and careful design techniques, while ease of operation is provided by front panel controls that let you adjust your Transmit Audio, Receive Audio and Transmit Delay "on the fly".

The SignaLink^TM USB works with virtually ALL radios and can be attached to the Mic jack, Data Port or Accessory Port. Most customers will want to attach the unit to the back of the radio (Data or Accy Port), as this will allow the microphone to stay plugged in. A wide selection of Fully assembled radio cables are available for virtually all common base and mobile radios, as well as a number of Icom, Kenwood, Yaesu, Baofeng, Wouxun and similar HTs. A special un-terminated radio cable is available for radios that use a non-standard connector, or for other applications when you want to build your own radio cable.

The SignaLink^TM USB comes fully assembled and tested. As with all Tigertronics products, it employs Surface Mount construction, and every unit is Robotically Assembled in our own factory to ensure maximum performance and reliability. All components are of the highest quality and every unit undergoes the same stringent quality control and inspection standards that you have grown to expect from Tigertronics! We invite you to compare every aspect of the SignaLink^TM USB to other sound card interface products. We think you will agree that we have offered a level of innovation, quality, and value that cannot be beat!

Features:

FCC Certified - Unlike some 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 Rules.
Built-in 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.
Simple 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 computer audio cables to get mixed-up!
Easy 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 virtually always done completely by the SignaLink front panel "RX" control (the "Recording" slider normally needs no adjustment).
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 fly"!
Works with virtually ALL Radio Mic, Data, and Accessory Ports - The SignaLink USB works with virtually 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!
Supports virtually All Sound Card Digital & Voice Modes - The SignaLink USB supports virtually ALL Digital and Voice modes that are available for sound card interfaces. This includes today's hottest modes like FT8, FT4, JS8CALL, VARA HF, VARA FM (Wide and Narrow), MSK144, PSK31, JT65, WSPR, FREEDV and EchoLink, as well as traditional modes such as RTTY, SSTV and CW. Virtually ALL standard sound card communications programs will work with the SignaLink USB.
Complete 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 wide bandwidth audio transformers and a relay-based PTT keying circuit.
Transmit Audio / "Side Tone" Monitor 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.
External Speaker 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.
No 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 an audio cable to be installed between the SignaLink USB and the radio. This is never needed if you attach the SignaLink to a standard radio Data or Accessory Port.

What's Included?

The SignaLink USB is supplied with the following items:

Fully Assembled Detachable Radio Cable - The SignaLink part number determines which radio cable is supplied with the unit. Cables are available for virtually all base, mobile and heldheld radios. An un-terminated radio cable (bare wires on the radio end) is available if you need to build your own cable. All radio cables are approximately three feet in length. Some are also available in a 6ft length for a small additional charge. Please see our SignaLink USB Product Guide to find the part numbers that are needed for your radio. You can search this guide for your radio model and see exactly part numbers we recommend for the radio cable, jumer module and the SignaLink USB .
USB Cable - This cable connects the SignaLink USB to your computer. It is approximately six feet in length. A 10ft USB cable is also available upon request for a small additional charge.
Audio Cable - This cable is approximately three feet in length and is normally only used with radios that do not have Receive Audio on the Mic jack. Note that this cable is packaged with our microphone radio cables and select others that might require it. It is not normally supplied with Data/ACC cables because it is not needed.
Jumper Wires - A set of six 24 AWG wires are precut and stripped, and are used to configure the SignaLink for your specific radio. No soldering is required - The jumpers simply push into a socket on the circuit board! See our jumper settings page for jumper settings for most popular radios. Settings for other radios can be easily obtained by following the step-by-step procedure in the SignaLink manual, or by contacting our Technical Support Staff.

If you do not want to install jumper wires, then be sure to see our Plug & Play Jumper Modules. They are inexpensive and greatly simplify installation! They're also the easist way to change your configuration when moving the SignaLink to a differnet radio!
Allen Wrench - 3/32" size. Used to open the SignaLink USB case.
Rubber Feet - These are included with every SignaLink USB and can be installed by the user if desired.
Printed Installation Manual - The SignaLink manual provides clear, step-by-step installation instructions that can easily be followed by users of all experience levels. Troubleshooting Tips and an Audio Level Adjustment procedure are also included.
FREE Telephone Tech Support - If you have any questions, or if you need assistance with the installation of your SignaLink, our Technicians are available to help you. Click here for information on contacting Tech Support.
