K1EL Morse Tutor



The MTB was designed to be a low cost educational platform for learning and practicing Morse code. Everything the student needs is on the board including touch pad inputs. Optimal touch paddle sensitivity is maintained by an auto-calibration algorithm. The MTB is implemented in a Microchip PIC16F1825 microcontroller and utilizes a special version of the K1EL K16 keyer core which provides a wide range of features. Setup commands are directly entered on the paddles in Morse code. All settings and messages are stored in nonvolatile memory so that they are preserved when the keyer is turned off. The K16 keyer core has many original features not found in other keyers.
