Signal Stage

Receive a message, send a reply

Each lesson introduces new characters through listening and echo practice, followed by a short memory exercise. Then an incoming message appears as grouped dots and dashes. Type its translation, including spaces between words, before sending the reply. You can skip the introductory drills; a new message attempt still starts with receiving.

The first incoming message is MEET. Your reply is MEET ME. A 36-character reference shows the letters and numbers and lets you hear each one. Hide the written incoming signal when you want to practice by listening.

Guided sending shows the pattern when hints are enabled. Recall hides it until you ask. Both modes help with spaces between characters and words, and require the correct character before moving on. Continuous reads the marks and pauses you send, then checks the whole decoded message, including word spaces.

First steps and controls

1. Choose Start learning and open the first link. Select Guided, Recall or Continuous, then choose Learn & echo or Skip to receiving.
2. Read or hear the incoming signal. Enter its translation and choose Check translation. A wrong answer stays available for correction.
3. Press and release Space or hold the large on-screen key with a pointer or touch. A short hold makes a dot; a longer hold makes a dash. D and F, or the Dot and Dash buttons, add marks without holding.
4. In Guided and Recall, choose Finish character when the pattern is ready. Enter also finishes from the main play area or transmit key. Backspace clears the current marks. In Continuous, use pauses to separate characters and words, then choose Check transmission.
5. Escape pauses active sending. Q exits practice. Tab moves between controls, and Enter activates a focused button. Text fields keep their normal typing controls.

Settings includes signal speed, volume, pitch, mute, text size, stronger contrast and reduced motion. Codebook and help remain available during practice. Guided and Recall do not grade timing; Continuous uses the game’s stated practice windows. Speaker, headphone and input latency have not been calibrated.

Keep a practice record

Each letter and number has a reading bar and a sending bar. A bar fills after five correct instances in a row in that direction. An attributable error resets the corresponding streak; error totals remain visible. Hints, repeats and targeted drills count. A full bar records practice and does not certify mastery.

Local profiles keep separate records. The game saves accepted progress in this browser, and Continue returns to a saved attempt. During active sending, F5 saves the last accepted character boundary and F9 restores it. An unfinished character is cleared on restore; Continuous starts a fresh signal stream.
