HELP vs SOS: Which Should You Use?
While both HELP and SOS communicate distress, they serve different purposes. SOS (··· −−− ···) is the internationally recognized distress signal with a specific legal meaning — sending SOS indicates a life-threatening emergency and obligates nearby stations to respond. HELP is simply an English word with no special status in international signaling protocols. If you are in genuine danger and signaling with Morse code, always use SOS rather than HELP. SOS is also easier to send: its symmetrical pattern of three-three-three is simpler than the varied patterns in HELP.
How to Signal HELP in Morse Code
To tap or flash HELP in Morse code: start with H (four quick taps: ····), pause briefly, then E (one quick tap: ·), pause, then L (tap-long-tap-tap: ·−··), pause, then P (tap-long-long-tap: ·−−·). Remember the timing: a dash is three times as long as a dot, gaps between elements within a letter are one dot-length, and gaps between letters are three dot-lengths. At 15 words per minute, the entire word HELP takes about 3-4 seconds to transmit.
Emergency Morse Code Signals Beyond SOS and HELP
International Morse code includes several other emergency and urgency signals. MAYDAY (spoken voice) replaced SOS for voice radio but SOS remains valid for Morse. The prosign XXX (−··− −··− −··−) indicates an urgency message that is less critical than a distress call. PAN-PAN (·−−· ·− −· / ·−−· ·− −·) signals urgency without immediate danger to life. In aviation, squawk code 7700 is the transponder equivalent. Knowing SOS is the most important — it works across languages and is recognized by rescuers worldwide.
Teaching Children and Beginners to Signal HELP
HELP is one of the first practical words many survival courses teach in Morse code after SOS. The word uses four common letters that beginners can learn quickly. A helpful mnemonic: H has four dots like four quick heartbeats when scared, E is the simplest single dot, L starts with a dot then has a dash and two more dots, and P starts with a dot followed by two dashes and a final dot. Practice by tapping on a table until the rhythm becomes automatic — in a real emergency, muscle memory matters more than mental recall.
