What is R in Morse code?

R in Morse code is ".-.", spoken di-dah-dit. It is three elements long (dot dash dot) and takes 420 milliseconds to send at 20 words per minute. It sits three steps from the root of the Morse code tree.

Which Morse code characters are confused with R?

R (.-.) is easy to confuse with K (-.-), its mirror image with dots and dashes swapped, and with G (--.), S (...) and W (.--), each of which differs from it by a single element. Practise them back to back until the difference is a sound rather than a count.

How do you learn R in Morse code?

By its sound, not its shape: R is spoken di-dah-dit. Listen to it at full speed instead of counting its elements. MorseForge's 7-day plan teaches it on day 3, together with S, U and W.

R in Morse code

R in Morse code is ".-.": dot, dash and dot, spoken "di-dah-dit". It is one of the 8 three-element letters, so it sits three steps from the root of the Morse code tree, and it is the mirror image of K, which is dash-dot-dash. The 7-day plan teaches R on day 3. At 20 words per minute it takes 420 milliseconds to send.

Where R sits in the Morse code tree

The path through the Morse code tree to R: from the root, a dot to E, a dash to A then a dot to R.

In the Morse code tree a dot branches left and a dash branches right, so every character sits exactly where its own code leads. R sits three steps from the root, directly below A. From R, a dot leads to L.

Characters confused with R

R is easiest to mistake for K, G, S or W. Practise them back to back until the difference is a sound rather than a count.

How to learn R

7-day plan

The plan teaches R on day 3, together with S, U and W. Learn it by its sound, "di-dah-dit", at full speed rather than by counting its elements.

In the Koch method it is character 3 of 36.

Practise

Practice brings R back just before you would forget it, in all three skills: copying it by ear, reading it, and sending it yourself.
