Oct 17, 2023 · With an Arduino, an LCD module and a few components you can have your own pocket-sized "secret decoder" that will do up to 80 wpm, enabling even you the "noob" to dive feet first into the CW bands with an electronic set of "swimmies!"

A CW encoder written for the ARRL and presented during Hamvention 2024. BOM and Circuit Diagrams Available in the ReadMe file. Please feel free to use this as you like.

Jan 7, 2023 · How tough would it be to build a morse code decoder? Or otherwise known as a cw (for continuous wave) decoder for the ham radio operators out there. The internet search engines led me to these instructions by Hjalmar Hansen OZ1JHM and this video on the “learnelectronics” youtube channel.

Jun 13, 2024 · This device is especially useful for HAM radio beginners, and also SW listeners who can monitor CW communications without knowing Morse code.

Mar 31, 2014 · Using the 567 decoder keeps the hardware interface simple, and uses logic-level signals for both transmitting and receiving. Most of this article covers the 567 circuit, but the receiver can alternatively read audio tone data from the A0 pin of the UNO.

If the signal is weak, noisy or keyed with a paper clip, even the best decoder, namely your ear, could have difficulty perceiving a message. Do you want to play with CW (telegraphy) decoder, so this is a very nice little project that will not cause you much anguish. My version of the program can be DOWNLOADED here...

Apr 22, 2023 · This is an open source Arduino based CW (Morse Code) keyer with a lot of features and flexibility, rivaling commercial keyers which often cost significantly more. The code can be used with a full blown Arduino board or an AVR microcontroller chip can be programmed and used directly in a circuit.

I came across a CW Decoder based on an Arduino Uno implementing the Goertzel algorithm, and have lashed together a prototype which works quite well. The CW Decoder circuit and code come from Hjalmar, OZ1JHM and are described in his web page A VERY simpel CW decoder EASY BUILD. Thanks Hjalmar!

Explore the circuit, controls, and setup of this innovative device designed by Allen Baker (KG4JJH). Decode Morse code efficiently, providing a valuable tool for operators, from novices to veterans, and offering a hands-on experience with Arduino technology.

A diy project to develop a simple cw decoder using the Arduino microprocessor. The code is optimised for the limited power of the Arduino and includes novel processing to track the transmitter frequency.
