<P> In the United Kingdom, many people learned the Morse code by means of a series of words or phrases that have the same rhythm as a Morse character . For instance, "Q" in Morse is dah - dah - di - dah, which can be memorized by the phrase "God save the Queen", and the Morse for "F" is di - di - dah - dit, which can be memorized as "Did she like it ." </P> <P> A well - known Morse code rhythm from the Second World War period derives from Beethoven's Fifth Symphony, the opening phrase of which was regularly played at the beginning of BBC broadcasts . The timing of the notes corresponds to the Morse for "V", di - di - di - dah, understood as "V for Victory" (as well as the Roman numeral for the number five). </P> <Table> <Tr> <Th> Category </Th> <Th> Character </Th> <Th> Code </Th> </Tr> <Tr> <Td> Letters </Td> <Td> A, a </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> B, b </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> C, c </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> D, d </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> E, e </Td> <Td> <Table> <Tr> <Td> </Td> <Td> </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> F, f </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> G, g </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> H, h </Td> <Td> <Table> <Tr> <Td> </Td> <Td> </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> I, i </Td> <Td> <Table> <Tr> <Td> </Td> <Td> </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> J, j </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> K, k Prosign for "Invitation to transmit" </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> L, l </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> M, m </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> N, n </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> O, o </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> P, p </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> Q, q </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> R, r </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> S, s </Td> <Td> <Table> <Tr> <Td> </Td> <Td> </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> T, t </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> U, u </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> V, v </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> W, w </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> X, x </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> Y, y </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Letters </Td> <Td> Z, z </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Numbers </Td> <Td> 0 </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Numbers </Td> <Td> </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Numbers </Td> <Td> </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Numbers </Td> <Td> </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Numbers </Td> <Td> </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Numbers </Td> <Td> 5 </Td> <Td> <Table> <Tr> <Td> </Td> <Td> </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Numbers </Td> <Td> 6 </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Numbers </Td> <Td> 7 </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Numbers </Td> <Td> 8 </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Numbers </Td> <Td> 9 </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Punctuation </Td> <Td> Period (.) </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Punctuation </Td> <Td> Comma (,) </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Punctuation </Td> <Td> Question Mark (?) </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Punctuation </Td> <Td> Apostrophe (') </Td> <Td> <Table> <Tr> <Td> </Td> <Td> − − − − </Td> </Tr> </Table> </Td> </Tr> <Tr> <Td> Punctuation </Td> <Td> Exclamation Point (!)
