Morse code prosigns you can hear
Prosigns are procedural signals — often written as two letters with a bar, sent as one run-on pattern without the usual letter gap. SOS is the famous one; traffic also uses AR, SK, BT, KN, and others. Tap a row to hear it.
Procedural signals — usually sent without the normal letter gap. Practice reference, not a bandplan.
Tap a prosign to hear the run-on pattern.
When to use
Learning what you hear at the end of a practice QSO; decoding a puzzle that uses SK/AR; linking SOS to the wider prosign idea; comparing run-on timing to letter-spaced letters.
Better elsewhere
Plain punctuation → punctuation page. SOS rhythm → SOS page. Operating rules for your country stay in your license manual.
Assumptions
A practical subset of common amateur/practice prosigns; exact club preferences may differ. Play uses the shared audio engine after a tap.
Examples
Input
Play AR (end of message)
Result
Hear run-on .-.-. — not A gap R
End-of-message habit in practice traffic.
Input
Play SK · then open SOS
Result
End-of-contact vs continuous distress pattern
Input
Play BT · compare to = on punctuation charts
Result
Procedural break vs punctuation row — know which page you need
How it works
- Table of symbol → element pattern for a common set.
- Tap a row to play the continuous pattern via shared audio.
- Compare to letter-spaced A then R when teaching the gap difference.
Run-on element pattern · no letter gap inside the prosign · dit ms ≈ 1200 / WPM
Gotchas
- Writing AR as two letters with a space is not how the prosign is sent.
- Charts disagree on rare signs — we stick to the common set.
- SOS is a prosign; treating it as three dictionary letters teaches the wrong gap habit.
- Club charts may list rarer signs — we stick to the common set.
Compare
Letter gap vs prosign gap
Writing AR as A then R with a normal letter space is not how the prosign is sent. Prosigns are often one run-on pattern. Tap a row here to hear the continuous form; compare to letter-spaced A + R on the translator.
