Historically radio communication has been a big part of military and Armed Forces communication. This usually means jamming your frequency with interference making it impossible to use that frequency. Most major airlines use the alphabet to communicate passenger name records (PNRs) internally, and in some cases, with customers.

Guide to Radio Communications Standards RI DEM ERP 4-3, p. 1 . To enable the U.S., UK, and Australian armed forces to communicate during joint operations, in 1943 the CCB (Combined Communications Board; the combination of US and UK upper military commands) modified the U.S. military's Joint Army/Navy alphabet for use by all three nations, with the result being called the US-UK spelling alphabet. o Rhythm.  ICAO's directions to him were that "To be considered, a word must: After further study and modification by each approving body, the revised alphabet was adopted on 1 November 1951, to become effective on 1 April 1952 for civil aviation (but it may not have been adopted by any military). Red on Red: Enemy-on-enemy fire. For instance, “Alpha” means “A,” “Bravo” means B, and so on. VP is used by the military, maritime /air service, civilian emergency response service, etc. They should be used whenever appropriate. Back in 1937, the Association of Public Safety Communications Officials (APCO) developed the so-called ‘ten-codes’. Radio Regulations and Additional Radio Regulations (Atlantic City, 1947), 1959 Administrative Radio Conference (Geneva, 1959), International Code of Signals for Visual, Sound, and Radio Communications, United States Edition, 1969 (Revised 2003), "Delta" is replaced by "Data", "Dixie", or "David" at airports that have a majority of, "Lima" is replaced by the old RAF word "London" in. Military communication - Military communication - World War II and after: In communications electronics, World War II was in one sense similar to World War I: the most extravagant prewar estimates of military requirements soon proved to represent only a fraction of the actual demand. Contrary to what Hollywood would have you think, Roger only means "last transmission received/u… Not only was Popov’s receiver suitable for radio communication, but he also used it, with some added components, for the automatic recording of lightning discharges. VP maximizes clarity of spoken communication and reduces misunderstanding. ", "The Postal History of ICAO: Annex 10 - Aeronautical Telecommunications", "What is the standard phonetic alphabet? 2.
