Raspberry Pi4 CW Keyboard

[Chuck aa0hw]

Using just a Raspberry PI and the RECRI KEYER's  software CW KEYBOARD

with the Pi's own native bcm2835 headphone output

This setup is QRQ fast from TYPING on the SCREEN and hearing the CW AUDIO SIDETONE from the pi4's headphone jack     Recri Keyer has a massive amount of adjustable CW parameters    from CW pitch, to Raised Cosine WINDOW(s)...weight by percentage, weight by time, rise/fall time, volume      it has it all...

in addition to just having the Pi4 CW Keyboard play out its headphone jack,  you can use it to KEY CW on your RIG and receive audio from the RIG,  and you can use it to send CW to another OP over ip and receive CW from another OP over ip     this example uses ZiTA-NJbridge for REMOTE RIG operations and Gstreamer for CW AUDIO over IP operations
