How to Say "No" in Morse Code?
Short answer: No in Morse Code is: -. ---
That's N (-.), O (---) with a single space between letters. Because Morse is timing-based, you can send "NO" with beeps, flashlight blinks, phone vibration, tapping on a surface, or over radio—no special gear required.
Letter-by-Letter Breakdown
N
-. (Dash then Dot)
O
--- (Three Dashes)
Put together with a single space between letters: -. ---
The contrast between N's dash-dot and O's three dashes makes this a highly distinctive signal.
Timing Rules (The Key to Clarity)
Morse isn't just dots and dashes—it's proportions. Here is the proper timing:
| Dot | = 1 unit |
| Dash | = 3 units |
| Gap within letter | = 1 unit |
| Gap between letters | = 3 units |
The "NO" Rhythm:
To send Morse code NO cleanly: key -. → wait for a 3-unit gap → then key ---. Keep the tempo steady; clarity beats speed every time.
How to Send It
Flashlight
Dots are quick blinks; dashes are 3x longer. Blink N (-.), pause, O (---).
Whistle/Horn
Short vs. sustained blasts give clear contrast. Send three full "NO" groups.
Tapping
Tap counts precisely (1 for dots, 3 for dashes). Keep the 3-unit letter gap crisp.
Radio / Key
Key at a comfortable speed. After "NO," you can acknowledge instructions.

2-Minute Practice Plan
Listen & Echo
Play the -. --- audio at the top of the page once, then immediately echo it with taps.
Count It Out
Say "one" for dots; "one-two-three" for dashes; "one-two-three" of silence between letters.
Self-Check
Record a quick clip of yourself sending it and confirm your dashes are exactly triple the dot length.
Common Mistakes
Too-short dashes
If dashes are clipped, O (---) can be misread as T (-) or M (--).
Collapsed letter gap
Without the full 3-unit gap, N and O smear together. Exaggerate the pause while learning.
Extra dot on N
N is -. (dash then dot), not -- or .-..
When to Use "NO" in Morse
Quick Refusals
A short, unambiguous negative reply in noisy or low-light settings.
Group Coordination
Paired with YES in Morse Code, it enables clear go/no-go signals.
Learning Bridge
The contrast between N and O builds dash control before learning longer words.
After this, try SOS in Morse Code or friendly starters like Hi in Morse Code.
