Mike, AB1YK – Panadapterįinally, Mike, AB1YK brought in a number of projects that he has done including a Panadapter and a CW Generator. To make CW workable we used a CW reader and keyer with preloaded exchanges and a keyboard. This was a big hit with the kids who visited us for ARRL Kids Day. On the left is the most recent decoded text. Just blind decoding of random speed Morse code, without using smart DSP algorithms, dont get good results. All these decoders works somehow, but two of them are the best in my opinion, mainly because they use complex DSP algorithms. When you hook up a monitor and a straight key to the Raspberry Pi, it will decode what you key in. To access it, go to the main screen which shows the current audio spectrum and bandpass filter settings, then press the mode button to cycle between bandpass filter, bandstop filter, and morse decoder mode. Are a lot of CW decoders on the internet available, and I tested (just for fun) many of them. I ( AB1QB) demonstrated a Raspberry Pi project that I built over the holidays. I’m looking forward to using this to get the last 20 80m contacts for my 5 Band DXCC! Anita AB1QB – CW Pi He has programmed our MicroHam system to automatically have the box switch the matching system as we tune through the 80m band. Dennis hows plans for his KX2 Standįred, AB1OC brought an 80m band matching system that he will install in order to make our 80m delta loop be resonant across the band. New ':' notation to specify the passband center frequency in the URL and frequency entry box. Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. 'mykiwi:8073/extcw,500' will lock the cw filter at 500 Hz. Dave K1DLM – Heakthkitĭave, K1DLM showed us a Heathkit that he plans to build.ĭennis, K1LGQ had another explosive presentation when he showed us a KX2 stand that he built. The cw extension parameter will lock the frequency of the cw decoder filter and keep it from tracking with changes to the Kiwi passband. Hamilton, K1HMS brought Antenna Switches that he had built. Dave K1DHP – VLF Detectorĭave, K1DHP showed us the VLF Detector that he built. A simple Morse Code Decoder Based on the STM32 ARM Processo - GitHub - jmharvey1/STM32CWDecoder: A simple Morse Code Decoder Based on the STM32 ARM Processo. Bob KB1TEK – QRP Kitsīob, KB1TEK brought some QRP kits that he had built. Our Programs Chairperson, Scott, NE1RD led it off by showing us some kits he had built, including the K1EL PaddleStick Keyer that we will be building for the February Tech Night. This year’s Project Night was full of interesting projects built by our members. Every January Meeting we hold Project Night, where members bring in and share recent homebrew projects that they have built.
