Arduino Morse Decoder LCD DSP Goertzel: A Portable and Versatile Tool for Amateur Radio Operators

In recent years, there has been a resurgence of interest in amateur radio among hobbyists and professionals alike. One aspect of this hobby that has remained popular over the decades is the use of Morse code to send messages over the airwaves. For those who wish to send Morse by hand, a portable unit with an LCD display and rotary control for adjusting speed was created using Arduino technology.

The device, known as the VK2IDL Morse Encoder, allows users to type their Morse code via a keyboard or connect it to a manual key or Morse paddle for hands-free operation. The encoder is based on an Arduino Nano, which provides a compact and user-friendly interface. The unit can be used with a variety of inputs, including a keyboard, manual key, and Morse paddle.

The LCD display shows the Morse code being sent in real-time, providing users with immediate feedback as they transmit. A rotary control allows for adjustable speed settings from 6 to 30 words per minute (wpm), making it easy to adjust the transmission speed to suit individual needs.

In addition to its keyboard input option, the device also includes hardware inputs for manual key and Morse paddle connections. These secondary options were added to provide users with more flexibility in how they choose to send their Morse code messages.

The VK2IDL Morse Encoder was designed with portability in mind, making it easy to take on the go or use in a variety of settings. Its compact size and lightweight design make it an ideal companion for amateur radio operators who need a reliable and user-friendly tool for sending Morse code.

Overall, the Arduino-based Morse decoder LCD DSP Goertzel is a versatile and portable tool that has been designed with the needs of amateur radio operators in mind. Whether you're just starting out with Morse code or are looking to improve your skills, this device provides a unique and innovative way to send messages over the airwaves.
