CW Decoder 3.66

View and analyze continuous waveforms to get the information they carry, like Morse code. Select between line and waterfall displays modes and tweak such parameters as signal strength, text display size, character spacing, code status, WPM counters, and others.

CW Decoder was designed to allow CW operators to see, hear, and display as text CW signals from their receivers and to transmit CW using the serial port of the computer. This is accomplished by routing the audio from the receiver output to the audio (MIC In) input of the sound port of the computer.
