Count what transmission actually costs
Supported/unsupported characters, dots, dashes, words, signal units and estimated transmission time are calculated from the same Morse engine and selected timing profile.
International Morse boundary
WebToolArc follows ITU-R M.1677-1 for the International Morse alphabet and the 1-dot / 3-dot / 7-dot spacing relationships. Common extensions are labeled separately, and learning-oriented Farnsworth spacing changes gaps without changing dit/dah character speed.
