I have made some software changes to suit my circumstances. The CW decoder uses the same basic LM567 circuit designed by Budd Churchward WB7FHC which is connected to an Arduino Nano.

And for the final part, the CPU interfaces to the LCD line display, sending ASCII characters to it and monitoring LCD status. VK2IDLCWDecoder A Morse Code Decoder based on WB7FHC's Simple Morse Code Decoder. Each of the symbols that are received, an equivalent 'code word' is assembled and is convert to its ASCII equivalent character for display. This output drives both an input to the PIC16F84 microcontroller and an LED that is used as a receiver tuning aid.Īnother part is the PIC16F84 microcontroller, its function is to measure the duration of the one-zero input string from the tone decoder, and translate the pattern into DOTs, DASHs, symbol spaces, character spaces, or word spaces. The next part of the project is the PLL (phase lock loop) tone detector/decoder NE567 its output is a one-zero pattern replicating the dots-and-dashes sequence of the received signal.

Its band edges are determined by the size of the coupling capacitors, and the feedback capacitor between the transistor's base and collector terminals. pre-programmed micro controller - no programming required. The project's first part is composed of an electret microphone followed by a common emitter follower amplifier this transistor amplifier also acts as a first level bandpass filter. Compared to voice, Morse code is less sensitive to poor signal conditions, yet still comprehensible to humans without a decoding device, therefore, a useful alternative to synthesized speech for sending automated data to skilled listeners (radio operator) on a voice channel. Each character (letter or numeral) is coded/represented by a unique sequence of dots and dashes. ( Budd's Sketch is available here) I simply downloaded the sketch and uploaded it to the Arduino.

As mentioned Budd Churchward had created a series of videos on how he wrote the Sketch, created a PCB and published his code. I used the limited shared knowledge and discovered that the electronics is. express, freight, 938.07 coal, 407.80 decoding weather bulletins, 300. I ventured further and wanted to know what electronics Budd was using to achieve this excellent little project. 107.50 sundries, 35.51 1.353 76 Canadian Fairbanks- Morse Company. Morse code is used in telecommunication it is a method of transmitting and receiving coded information. Thursday, 30 July 2015 CW decoder The Arduino This is arguably the simplest part of the project. I stumbled across a video on YouTube where Budd Churchward showed his Arduino copying and decoding CW straight off the HF band and at a reasonably high speed.
