HELP ME in Morse code is ···· · ·—·· ·——· —— ·, written as .... . .-.. .--. -- .. Six letters across two words, 16 signals total. It is a more explicit distress phrase than HELP alone — specifying that the sender personally needs assistance — and can be transmitted by any two-state medium: radio, light, sound, or tapping.
Letter-by-Letter Breakdown
- H —
....— four dots - E —
.— one dot - L —
.-..— dot-dash-dot-dot - P —
.--.— dot-dash-dash-dot - (word gap — 7 units of silence)
- M —
--— two dashes - E —
.— one dot
The word gap between HELP and ME — seven units of silence — is the longest pause in the sequence. It must be noticeably longer than the letter gaps (three units) and much longer than the intra-letter gaps (one unit). This timing is what makes the two-word structure readable to a receiver.
Use the Translator to hear HELP ME played correctly with all timing. Type HELP ME and press Play at 5 WPM to hear the gaps clearly, then increase the speed.
How to Signal HELP ME
Flashlight: H — four short flashes. E — one short. L — short-long-short-short. P — short-long-long-short. Pause (7 units — about 2–3 seconds at slow speed). M — two long flashes. E — one short. Pause. Repeat.
Tapping on any surface: Same pattern, same timing. Four quick taps (H), one quick tap (E), quick-long-quick-quick (L), quick-long-long-quick (P), pause, long-long (M), one quick (E). Metal pipes and walls carry the signal furthest. Tapping through walls or debris to signal rescuers has saved multiple lives in building collapse scenarios.
Sound (whistle or horn): Three short blasts = H, one short = E, short-long-short-short = L, short-long-long-short = P, pause, two long = M, one short = E. A whistle is significantly louder than a human voice at the same effort and carries through walls and debris.
Radio: Send HELP ME in Morse on Channel 16 VHF (maritime distress, 156.8 MHz) or 121.5 MHz (aviation). On amateur radio, 14.300 MHz is the maritime mobile calling frequency. If voice is available, send MAYDAY instead — faster response in modern emergencies.
HELP ME vs SOS vs HELP — Priority and When to Use Each
In a genuine emergency, transmission order matters:
SOS (···———···) first. Nine signals, one continuous unit, internationally standardised, legally recognised. Faster to send than HELP or HELP ME. Any trained operator worldwide responds immediately. This is always the priority.
MAYDAY on voice radio second (if available). Voice MAYDAY gets faster modern response — coast guard can immediately request position, vessel name, and situation.
HELP ME as a supplement or alternative. More explicitly communicates that the sender needs assistance, not just attention. Useful when communicating with someone who has partial Morse knowledge but may not know that SOS means distress specifically. The English words are self-explanatory even to partial Morse readers.
Teaching HELP ME to Non-Morse Readers
The pattern three-three-three (SOS) and the word HELP ME are both worth teaching to people who accompany you in wilderness or maritime situations — even if they will never formally learn Morse code. Knowing two distress signals and when to use them takes less than 10 minutes to teach and could matter enormously.
The teaching sequence: show SOS first (simplest, most important). Then show HELP ME as the backup. Demonstrate with a flashlight or by tapping. Have them repeat both patterns back to you. Confirm they can send SOS correctly from memory — that is the minimum.
Learning HELP ME for the Quiz and Practice
HELP ME uses six letters: H, E, L, P, M, E. All covered in the first six lessons of the Learn page. M is in Lesson 2 (as one of the six simplest letters). H and E are in Lesson 1. L and P are in Lessons 4 and 6 respectively.
In the Two-Button mode, sending HELP ME involves:
- H: left-left-left-left
- E: left
- L: left-right-left-left
- P: left-right-right-left
- (word pause)
- M: right-right
- E: left
The Quiz Level 3–4 includes all these letters in timed questions. When you can identify H, E, L, P, M in under 3 seconds each, you can decode HELP ME by ear in real time.
The Psychology of Distress Signalling
One of the underappreciated aspects of learning distress signals is the psychological benefit of having a plan. People who have practised emergency procedures — not just memorised them, but actually practised the physical execution — consistently report lower panic responses in actual emergencies. The familiar action gives the brain something useful to do when the threat response is trying to hijack rational function.
Practising SOS and HELP ME until they are automatic costs very little time. Five minutes a week for a month. The return — the ability to signal correctly under stress — is disproportionately large. More importantly, knowing that you have a reliable distress signal reduces baseline anxiety in outdoor and maritime environments where emergencies are possible.
Building Emergency Morse Fluency Step by Step
The most efficient path to emergency Morse competency:
- Learn SOS (···———···) as a single continuous unit — not three letters. Practise until it is automatic by tapping, flashing, and in the Two-Button mode.
- Learn S (···) and O (———) as individual letters through the Lesson 1 audio flashcards.
- Add H, E, L, P, M — the letters needed for HELP and HELP ME. All in Lessons 1–6.
- Practise sending HELP ME as a complete phrase until consistent timing is automatic.
- Learn the distress frequencies: Channel 16 VHF (156.8 MHz marine), 121.5 MHz (aviation).
At step 4, you have meaningful emergency Morse capability. Steps 1–4 take most people about two weeks of 15-minute daily practice using this site's free tools. That is a very small investment for a skill that could matter in an extreme situation.

HELP ME in Context With Other Emergency Resources
Morse code is one tool in a broader emergency communication toolkit. Knowing its place alongside other tools helps you prioritise correctly:
- First priority: Voice radio MAYDAY on Channel 16 VHF (maritime) or 121.5 MHz (aviation). Fastest modern response, allows two-way communication immediately.
- Second priority: SOS by any Morse medium — radio key, flashlight, sound, tapping.
- Third priority: HELP ME and other explicit messages when communicating with someone who may not formally recognise SOS.
- Fourth priority: Ground signals visible to aircraft — SOS in large letters using available materials.
- Ongoing: Personal Locator Beacon (PLB) or EPIRB if carried — these transmit automatically on 406 MHz without operator action.
HELP ME in Morse sits at tier three — important to know, but not the first thing to reach for. The value of knowing it is the flexibility it adds: a second distress message you can send when SOS has already been transmitted and you need to communicate additional information to a receiver who is listening.

HELP ME With M — Why That Letter Matters
The M in HELP ME (——) is two dashes — the simplest all-dash pattern in Morse, second only to T (single dash). It is the Morse letter with the lowest information density and the most "weight" — slow, deliberate, unmistakeable. In audio, M sounds like a low steady sound twice in a row.
M is also among the six simplest letters in Morse code and one of the first taught in Lesson 2 alongside T, E, I, A, N. These six letters together cover the most fundamental patterns: single dot, single dash, two dots, two dashes, and the simplest mixed patterns. Once these six are automatic, adding the letters for HELP ME (H, L, P in addition to E and M) is straightforward.
The two-dash pattern of M is useful beyond HELP ME: 73 (best regards — the standard Morse farewell) ends with —— (M) as part of its last character sequence. MM is a common abbreviation for "momentarily" in CW contacts. Knowing M thoroughly means knowing a small but frequently useful character well.
For continued learning beyond HELP ME, the 12-lesson curriculum takes you from HELP ME's six letters through the complete alphabet. The Two-Button mode builds both sending and receiving speed. The Quiz Level 1 includes E and M — both are testable immediately after Lesson 2.
