CW Trainer: Learn Morse Code

Become a real CW operator. CW Trainer takes you from your first letters all the way to real QSOs and contests, with a radio simulator that sounds and responds like the real thing.

PROGRESSIVE KOCH METHOD
Learn Morse code one letter at a time with the proven Koch method. A 40-lesson curriculum, per-character accuracy stats, and automatic progression when you're ready.

QSO WITH AI OPERATOR
Have realistic radio conversations with an intelligent operator. You call, copy, exchange RST, name, QTH — and if you miss something, the operator repeats it, just like on the air. Every QSO is with a different station from around the world, and you get a score and coaching at the end.

CONTEST MODE
Train for CQ WW and WPX contests in Search & Pounce or Running. Pile-ups, rapid exchanges, ever-changing callsigns, and realistic error handling.

CALLSIGN TRAINER AND PILE-UP
Copy callsigns at speed, and pull single stations out of a pile-up across five difficulty levels.

MAKE IT YOURS
Speeds from 5 to 60 WPM, a level system from Bronze to Legend, daily reminders, and leaderboards to challenge other operators.
