Here’s something Jimmy Smith never tried – using a Hammond B3 organ to send coded message via HAM radio.
Forrest Cook developed Tonewriter – an experimental system that uses an Arduino and a Hammond B3 organ to encode text as a series of audio tones. The messages can then be displayed on a spectrogram – used by ham radio operators to visualize the audio that is received by a radio receiver.
Normally, the digitized audio data is fed into a decoder program. The tones generated with Tonewriter, though, can be directly read as characters in the waterfall display.
We’re still partial to more traditional uses of the B3 – but you can find out more about Tonewriter at Cook’s site.
