I have a rigpi3, but as the software used on it now is so out of date ie wsjtx and the pi os I have set up another sd card with bookworm, and have installed flrig as a radio control and wsjtx 2,70 rc6 flrig jscall etc.
I can use fldigi on all its modes including cw just using the usb cat port on my ftdx3000. But I would like to use the keyer board on the rigpi. It is based on the Winkeyer 3 IC and according to the rigpi manual is on serial port /devttyS0 at 1200 baud, but I have so far failed to get it to work on Fldigi apart from very occasional dits and dahs from the rigpi's speaker which were non reproducable.
Has anyone any idea or better still had it working without rigp os.
