The SignaLink SL-1+ provides all the features of our original SignaLink Model SL-1, "plus" more!  With full support for ALL radio Mic, Data, and Accessory Ports, the SL-1+ can be attached to the radio's Mic jack, or to the back of the radio (Data or Accy Port), so that you can keep your microphone plugged in!  This permits easy switching from Voice to Digital operation (great for SSTV!), and provides the same functionality as other more expensive interfaces.

In addition to supporting all available Digital modes, the SignaLink SL-1+ supports the latest Voice modes such as Internet Repeater Linking (EchoLink®, VOIP, etc.), Remote Base, and Voice Keyer operation.  Performance on these modes has been optimized by improving the sensitivity of our Auto-PTT circuit, and by the addition of a front panel selectable Variable Transmit Delay.   This variable delay is set at the factory for typical Voice applications, but can easily be adjusted to suit the operator's preference.

To make the installation of the SignaLink SL-1+ as easy as possible, we offer a large selection of fully assembled radio cables.   Cables are available for all of the common base/mobile Mic, Data, and Accessory Ports.  With the exception of our 13-pin cables, ALL of our radio cables are universal, and will work with ANY RADIO that uses the same connector type.  Our 13-pin cables are available in two specific configurations, one for Kenwood radios, and one for ICOM radios (they are not interchangeable).

The SignaLink SL-1+ comes fully assembled and tested.  It employs "State Of The Art" Surface Mount construction, and Robotic Assembly for maximum performance and reliability.  All components are of the highest quality, and every unit must pass stringent quality control and inspection standards.  We invite you to compare every aspect of the SignaLink to other sound card interface products.  We think you will agree that nothing else offers the same level of innovation, quality, and value!
