Operate Virtually All Sound Card Digital & Voice Modes!
The SignaLink sound card - radio interface combines legendary performance of the SL-1+ with a state of the art built-in low-noise USB Sound Card. This ground breaking innovation delivers 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.
Virtually ALL sound card Digital and voice modes are supported by the SignaLink unit. This includes traditional modes such as RTTY, SSTV and CW (to name a few), as well as today's hottest new modes like PSK31, WSPR, WINMOR, MT-63 and EchoLink. 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 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 cables are available for all common base and mobile radios. A special un-terminated radio cable is available for radios that use a non-standard connector, or for use with hand-held radios.
The SignaLink unit comes fully assembled and tested. It employs "State Of The Art" surface mount construction, and every unit is Robotically Assembled to ensure maximum performance and reliability. All components are of the highest quality, and every unit undergoes stringent quality control and inspection.
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 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 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 fly"!
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!
Supports All 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.
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 audio transformers and a relay-based PTT keying circuit.
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.
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..
