Hardware for learning Morse Code
Full-featured standalone learning tool. It is a multifunctional Morse code device that can be used as a practice trainer, keyer, file player, and Morse code decoder. It has built-in capacitance paddles and speaker. Check out this review video. Also works as a LoRa transceiver on 430MHz!
K1EL Morse Tutor Keyer Kit
Trainer and built-in capacitance keyer. It can be used for standalone practice. Or practice with a buddy by connecting an RCA cable between two kits!
MFJ-418 Code Tutor with LCD Display
Pocket-sized and convenient
W8BH Morse Tutor
The W8BH Morse Tutor is a great project for learning programming, for learning about hardware, for beginners to learn the Morse code, and for people who already know the Morse code to increase their speed, both in copying and sending, with either paddles or a straight key. You can build the Morse code tutor for $20 in parts. Check out Bruce’s website for other interesting projects. If you wish to use the Mega2560 instead of the ESP32 or STM32, check out KM4NFQ’s port of the code. Here is a short video clip demonstrating how to use two of them for practice with two people across the room.
K3NG CW Keyer
Open source Arduino-based CW keyer that has an incredible amount of features and flexibility, including K1EL’s WinKeyer compatibility. It can be used as a keyer and to learn Morse code. It can be used for send practice, and receive practice with Keyboard or Receive/Transmit Echo Practice.
OZ1JHM Timing Keyer
An open hardware and open source keyer that allows you to precisely diagnose any timing errors in your keying. Check out the review video. The software for it can be found here.
