What is it?

Fldigi is computer software used by amateur radio operators to transmit and receive digital messages in conjunction with a transceiver using the computers soundcard. Fldigi is short for fast light digital. There are many different ways to interface your transceiver with the computer, so it controls the radio directly, including using cat control, signalink, or rigblaster. For simplicity, we will be using the acoustic coupling method, which can be accomplished with any transceiver and requires no direct connections from the transceiver to the computer. Because there are several different operating systems, this will be a multi-part tutorial. Wayne County ARES uses fldigi frequently, because of this it is a good skill to have.
