An LM567 tone decoder, and support components.These available, as well, but this project uses the The prototyping shield, with a breadboard attached.The hardware I chose initially for the project controller consists of these essential (i.e., the modem functions) without the need to modify the user interface. make new hardware-based controllers that will do the modulation and demodulation This would allow people to do exactly what I am describing here This project has also convinced me that the ham community is in need of adoptingĪ standard modem interface for use with our more popular HF digital mode From here in, I will refer to the "modem",īut it is easily used as a terminal device by connecting to it using a terminalĮmulator such as miniterm or the Serial Monitor included in theĪrduino development environment. Program for real-time keyboard-to-keyboard QSOs, or integrated into a moreĬomplex software package, as the command and configuration interface is readily adaptedįor use in existing programs. I call this project a "modem," but it can be used with a simple terminal Through its A/D converter, and then do some basic DSP detection and filtering ofĪnalog CW signals, without the need for an external tone detector. Microcontroller also has enough computing power to read audio data directly I was surprised to learn that the little AVR Perform the morse code decoding operations, while offloading the tone detection My original goal was just to get the Arduino to This project has gone through several revisions, and now supports This article describes hardware and firmware forĮncoding and decoding of on-air CW using an modem based on these controllerīoards. I recently started playing withĪruduino boards for various ham applications, and thought a CW program for theĪrduino might be fun. Version 2.0 modem, based on the Teensy, see the Version 2.0Ĭode) is one of my favorite activities.
