Could someone give me a hand concerning the radio call letter used both in today's U.S. Military and those of the WWII era? Are they different from what I gather. The International Radiotelephony Spelling Alphabet (IRSA) is what the U.S. Military Phonetic Alphabet is called. The phonetic alphabet was created by the International Civil Aviation Organization (ICAO) to help decipher similar sounding letters and numbers between different countries and organizations. The United States Military relies on the NATO phonetic alphabet code covering letters A to Z (26 in all). Each letter is assigned a word so verbal communications.

The Military Alphabet (Phonetic from Alpha Bravo Charlie Delta to Zulu)

However, since many of the sounds were unique to the English language, a new version of the alphabet was developed in Latin America called the Ana Brazil alphabet. It was originally developed by the International Civil Aviation Organization and subsequently adopted by NATO North Atlantic Treaty Organisation among other significant global and national bodies covering telecommunications, maritime, and aviation.

Who made military call letters up? As an agency of the United Nations, it made sense for the ICAO to create a standardised alphabet, one which — even if made of English words — had sounds common to all languages and so could be spoken and pronounced internationally no matter what nationality the pilot.

Jean-Paul Vinay of the University of Montreal, a noted professor of linguistics, was charged with creating a new alphabet equivalency list and completed it in American radio stations announce their call military call letters at the top of each hour, as well as sign-on and sign-off for stations that do not broadcast 24 hours.

John's by the Dominion of Newfoundland government retain their original VO calls. In South America call signs have been a traditional way of identifying radio and TV stations. Some military call letters still broadcast their call signs a few times a day, but this practice is becoming very rare.

In Australia, broadcast call signs are optional, but are allocated by the Australian Communications and Media Authority and are unique for each broadcast station. Most European and Asian countries do not use call signs to identify broadcast stations, but Japan, South Korea, Indonesia, the Philippines and Taiwan do have call sign systems.

Britain has no call signs in the American sense, but allows broadcast stations to choose their own military call letters mark call sign up to six words in length. At least two of the terms are sometimes still used by UK civilians to spell words over the military call letters, namely F for Freddie and S for Sugar.
