Raspberry pi cw decoder4/1/2024 It tracks each instance on a channel which is rounded at 100 Hz of the audio signal frequency. The software detects peaks in the spectrum and starts a new decoder instance based on the detected peak signal frequency. With lower threshold you can enable weaker CW stations to be decoded but often you get just noise and the decoder produces garbage as visible in Fig 1. If you have Signal Browser open you can slide the horizontal control at the bottom to adjust the signal decoding threshold. I am interested getting feedback and improvement ideas to make the Bayesian decoder better.Ĭheckbox "Bayesian decoding" enables multichannel operation. Things are not yet well optimized so you are likely to see a lot of misdecoded signals. The following description explains the options and expected behavior in this alpha software version. I am running Windows FLDIGI version v3.21.83cw-a4 connected to PowerSDR v2.6.4 and my Flex3000 radio. below I have screenshot where I have the multichannel signal browser and Fldigi configuration screen for Modems / CW visible. This version has still multiple problems that need to fixed. The v3.21.83cw-a4 tarball sources and Windows version are available in Many thanks to Dave W1HKJ there is now an alpha build available also for Windows platform. Development of the Bayesian CW decoder is moving forward.
