 +==== Signalink USB ====
  
 +For Digimodes using **fldigi** and a Signalink USB soundcard requires a simple Cat5 ethernet cable to connect the IC-706 Mic socket to the Signalink USB soundcard. The Jumper information is here : [[https://tigertronics.com/sl_wirebm.htm]]

 +==== Rigctl / Hamlib ====
 +
 +
 +Connect serial RS232 from laptop to **IC-R75** and then C-IV cable between IC-R75 and IC-706. The IC-R75 will convert between RS232 and C-IV. Separate C-IV hex addresses means each radio can be addressed individually through one serial connection (/dev/ttyUSB0)
