Practice receiving International Morse Code without relying on four answer choices. Play a signal, type the character or word you heard, and use instant feedback to decide what should come back next. Start with eight easy-to-separate letters, progress through A–Z and numbers, or switch to short words when individual characters feel familiar.

A chart tells you what a signal looks like. Receiving practice trains the separate skill of hearing a complete rhythm and producing the answer before you look it up. The drill above keeps that loop short enough to repeat and gives missed signals extra opportunities to return.
The Starter 8 set uses E, T, A, N, I, M, S, and O. These signals introduce one-, two-, and three-element rhythms without asking you to recognize the entire alphabet immediately. When you can type them comfortably from sound, switch to A–Z and then add numbers.
Press Play Morse signal and answer from what you hear. The written dots-and-dashes hint is optional on purpose. Use it to verify a rhythm when you are stuck, then hide it again so recognition gradually moves from visual notation to sound.
A missed answer is added to the round's weak-signal list and becomes more likely to appear again. This is different from a completely random quiz: the session spends more of its limited questions on the signals that actually caused trouble while still mixing in the rest of the selected set.
Morse speed is not only about making every beep shorter. Character WPM controls the internal timing of each dit and dah. Farnsworth, or text, WPM can be set lower so the individual characters keep a clean faster rhythm while the gaps between characters and words are stretched.
20 WPM → characterControls how quickly the elements inside each character are sent. Raising this value shortens dits, dahs, and intra-character gaps together.
12 WPM → textKeeps the character rhythm at the selected character WPM but adds more space between characters and words. The text speed cannot exceed character speed.

There is no need to hide the alphabet forever; it is a useful reference. The problem is using the chart as the answer mechanism for every signal. A better training loop is to listen, commit to an answer, check the result, and use the reference only when you need to compare a pattern.
Increase the character set only after your current set feels recognizable from sound. If accuracy falls sharply, reduce the set or slow the text spacing instead of repeatedly guessing. Speed is useful when it measures recognition, not when it hides a basic character gap.
The word set adds sequences such as CQ, SOS, TEST, RADIO, and SIGNAL. These drills introduce letter spacing and require you to hold more than one character in memory, while still keeping the answer short enough for fast feedback.
One ten-signal round is a snapshot. Repeat the same set, notice which signals keep returning in the weak list, and compare accuracy at the same settings. When a set becomes easy, widen the pool or raise the character WPM a little rather than changing every variable at once.
This page generates controlled training audio. For four-choice recognition, use the Morse Code Quiz. To inspect a real microphone or uploaded CW recording, use the Audio Decoder instead.
These tools share the same International Morse definitions, but they solve different jobs. Choose by what you are trying to do rather than opening another page that looks similar.

You can practice directly on this page without creating an account. Choose a character or word set, play the Morse signal, type what you heard, and check the answer. Missed signals are weighted to return more often during the round so practice stays focused on actual weak spots.
A practical approach is to learn a small group of characters, listen to each complete rhythm, answer from sound, and add more characters only when recognition becomes comfortable. Short repeated sessions are easier to evaluate than trying to memorize an entire chart at once. Use the alphabet as a reference, not as the only form of practice.
There is no single reliable number because the goal matters. Recognizing a few common characters is different from copying full messages at conversational CW speeds. Track accuracy at a comfortable speed, practice regularly, and raise the character set or WPM when your current drills become consistently easy rather than aiming for a fixed number of days.
Yes. The listening trainer is free in a modern browser and does not require an account. The core receiving drills, speed controls, written hint, weak-signal repetition, and current-signal WAV download are available on the page.
Farnsworth timing keeps each individual character at the selected character speed while adding extra spacing between characters and words so the overall text arrives more slowly. It lets you hear the proper rhythm of a faster character without forcing the whole message to arrive at that same rate. Keep the text speed at or below the character speed.
Yes. Download WAV saves the current generated practice signal using the same character speed, Farnsworth text speed, 600 Hz tone, and International Morse timing used for playback. This page currently exports WAV, not MP3.
