Once again Tigertronics sets the pace in digital operating! The SignaLinkTM USB sound card - radio interface combines the legendary performance of our original SignaLinkTM with a state of the art 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 SignaLinkTM 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 SignaLinkTM 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 SignaLinkTM 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 modern 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 SignaLinkTM 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:


*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 an issue if you attach the SignaLink to your radio's Data or Accessory Port.
