Package xdemorse

http://www.qsl.net/5b4az/pkg/morse/xdemorse/xdemorse.html

xdemorse is a GTK+ graphical version of demorse, using the same
decoding engine as demorse.

It has an FFT-derived "waterfall" display of the incoming audio signal's
spectrum, as well as a 'scope-like display of the audio detector's output
and status of the mark/space discriminator ("slicer"). xdemorse also has
CAT for the FT-847 and this can be used to net the receiver's frequency
to the incoming signal, by clicking near its trace in the waterfall display.
