Morse code translator

Type a word or a phrase and get it in Morse code, with letters apart by a space and words by a slash. Or paste dots and dashes and read them as text. Both work as you type. Press Play to hear the code at the speed you choose.

Spacing below the speed leaves longer gaps between letters and words, as in the Farnsworth method: the letters keep their full-speed sound. Tap any code in the table below to hear it.

Letters, figures, punctuation and signals as the ITU defines them in Recommendation M.1677-1.1 A dot is · and a dash is −; the translator accepts ., ·, -, − and _ alike.

Prosigns

A prosign is sent as one character, the letters run together with no gap. Type it in angle brackets, such as <SK>, to put it in the code.13

ProsignCodeMeaning
<SOS>Distress signal
<AR>End of message (same code as +)
<BT>Break, new paragraph (same code as =)
<KN>Over, only the station called may reply (same code as ( )
<SK>End of contact
<AS>Wait
<SN>Understood (also written VE)
<HH>Error: eight dots
<CT>Starting signal (also written KA)
<K>Go ahead: invitation to transmit

How it works

Each letter becomes its ITU code, letters are kept apart by a space and words by a slash.1 Going back, the box reads dots as ., · or •, dashes as -, −, – or _, and a slash, a bar or a run of three spaces as the end of a word. A code that is not in the table shows as #.

The player follows the ITU timing: a dash lasts three dots, the gap inside a letter one dot, between letters three dots and between words seven. The ITU sets no speed unit; hams count words per minute by the word PARIS, which takes 50 dot lengths, so at 20 WPM a dot lasts 60 ms.2 With the spacing set lower, the letters keep the full speed and only the gaps grow, by the ARRL's Farnsworth formula.2
