About MorseCoder
A free International Morse translator and practice hub. Last verified: August 2026 — timing checked against ITU-R M.1677-1.
What this site is
MorseCoder exists so anyone can convert text to International Morse and Morse back to English in a browser — with CW-style audio, Farnsworth spacing, light, vibrate, and a trainer. The living standard we implement is ITU-R M.1677-1 (International Morse), not American / railroad Morse.
We do not claim a licensed Extra Class identity, an FCC callsign, a university affiliation, or years-on-air that we cannot document. Those claims previously appeared on this site and have been removed. The translator still works the same way; the trust signal is the published standard, not a borrowed ham ticket.
If you need on-air operating practice, treat this as a timing and recognition tool, then get instruction from a licensed amateur radio club or CW academy. We are not a licensing body and we do not issue callsigns.
The translator, alphabet audio, chart downloads, and practice trainer all use the same character table. A dot is one unit, a dash is three, the gap inside a letter is one unit, the gap between letters is three, and the gap between words is seven. When a page and the official recommendation disagree, the recommendation wins and the page should be corrected. Send the page address through the contact form. Corrections are checked against ITU-R M.1677-1 before they are published. There is no named editor on the byline. The publisher name on every page is MorseCoder.
What we will and will not say
Published standard
Letter timing follows ITU-R M.1677-1: a dash is three times a dot; intra-character gap is one dot.
