I have written new firmware for keyr.
This sends characters that can be read (maybe) off waterfall, or multi -tone Hell.
The attached .jpg is picture from mshv waterfall of test audio across desk and the

right click on the test .wav
www.qsl.net/zs1agx/shell/dc.wav
to save it
then, with spectran, select for input the .wav file.
or look at the attached picture from android soundanalyser..
