Smarter Morse Practice

The main screen shows decoded characters in a clear green window, with the raw dits and dahs underneath. You see exactly what you sent and where mistakes creep in, making it ideal for self-study and structured practice.

The built-in games include:

  • Listen – copy random character strings and reveal the answer to check accuracy
  • Random Letter – send the correct character and watch your percentage score climb
  • Send Random String – match a target string to progress
  • Send Letters – enter your own text and have the trainer play it back in Morse
  • ELIZA Interactive Mode – simulate a full CW QSO, exchanging name, QTH, RST, rig, antenna and WX

Flexible Hardware & Audio

  • 3.5 mm key input – tip/ring wired for dot/dash paddle or straight key
  • Configurable audio – choose tone and octave, set independent volumes for internal buzzer and 3.5 mm output
  • Key output or audio output on rear jack – drive LEDs/keying circuits or headphones/speaker, selectable in the menu
  • Right/left hand paddle setting – swap sides in software with a single tap

Wi-Fi Control & Web Interface

Setup is simple. On first power-up the Morse Trainer creates its own access point so you can connect from your phone, tablet or PC and enter your home Wi-Fi details. Once on your network, just browse to morsetrainer.local (or its IP address) to access the full web interface.

From the browser you can:

  • Adjust WPM, Farnsworth spacing and ELIZA response delay
  • Change key type (paddle/straight) and paddle handedness
  • Configure audio output and volumes
  • Update firmware over the air
  • Reboot or factory reset if needed

Always Up To Date

The firmware is under active development, with detailed release notes and frequent enhancements – from new games and localisation, to improved straight-key handling, mDNS/Bonjour support and more. Updates are delivered securely over Wi-Fi, and an emergency recovery mode is available if an update is interrupted.

Power & Portability

  • Internal 18650 Li-ion battery – around a day’s typical use per charge
  • USB-C charging – keep operating while you charge
  • Status LEDs – red while charging, blue when fully charged
  • Compact, handheld form factor – ideal for the shack, the sofa or the club room

If you’ve struggled with Morse in the past, or simply want a dedicated CW practice unit that grows with you, the TopBytes Morse Trainer is a powerful, modern tool to get you on the key and keep you improving.
