The CW Decoder is an excellent tool for viewing and displaying continuous wave data from multiple sources. The graphical spectrum, text lines, signal strength indicator, code status panels, WPM counters, and other features make it easy to interpret the data. I especially like the two display modes for visualization, line and waterfall, which make the data easier to understand. Highly recommended!

From the developer:
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.
