Please check project status on GitHub and the QSO recordings database. This decoder detects automatically the right tone and speed of the received CW signal. Expert Electronics - Topic: CW keying N1MM and SUNSDR3 SW. So here is a review of the project so far, and what I intend to do with the project going forward. This project exists of a Semi-automatic CW Decoder, Called Morseduino. вЂ“ that would show the letters as you transmit them out.

Also adding in an audio oscillator / switch & plug to insert a key on the oscillator вЂ“ then feed the output to the Arduino would immediately mean this kit could be used as a practice oscillator too. CW Decoder (Morse Decoder) with Arduino UNO ad 1.8 st7735r display. The location of the pins for the display / reset switch and audio OUT should be on the other side of the board. That solved the issue, and I have already corrected the fault for the next batch of boards.Дў further observations of the boards & the project as a whole have highlighted 2 further improvements to the project. I did fix this by attaching a wire to ground from one of the caps. But the 2nd and more serious issue is I forgot to ground 2 caps. That is an easy fix for the next version. Each character (letter or numeral) is coded/represented by a unique sequence of dots and dashes. CW-decoder by ELFA Radio (Requires a simple LM567 interface) QTC 9/1979. The first issue was sitting the capacitors a bit too close to the LM567 IC. This is a re-upload of a video where I show my latest Arduino project. I did make 2 small errors on these boards. All white and exactly how I laid them out. I tested it with an Arduino program called вЂcwfoxhuntвЂ™ which you can find here. I liked the project and built it in a home made enclosure made from PCB. I also wanted to box the project, so my rationale was to find a box first to work out the physical dimensions of the finished project.ДЄs with the Vero Version вЂ“ I created a layout that would fit on top of the UNO.ДЄfter submitting the design, and waiting a week I managed to get hold of 3 boards. In the VERON magazine of November 2015 there was a description of a CW Morse decoder built around an Arduino Nano. This was my very first attempt at creating a PCB, so nerves were a wee bit on the tense side.
