73 (magazine)
''73 Magazine'' (also known as ''73 Amateur Radio Today'') () was a United States–based amateur radio magazine that was published from 1960 to 2003.

History The first issue of ''73'' was published in October 1960 from Green's business offices in Brooklyn, New York. A major contributing editor was Ken Sessions, K6MVH, who wrote a column called "The Chronicles of 76", a reference to the FM transmitting frequency of 146.76 megahertz. Sessions also authored many books on the subject of amateur radio, and designed many of the how-to projects included in the magazine. Another contributing editor was Jean Shepherd, K2ORS.

Morse Code Abbreviations
Morse code abbreviations are used to speed up Morse communications by foreshortening textual words and phrases. Morse abbreviations are short forms, representing normal textual words and phrases formed from some (fewer) characters taken from the word or phrase being abbreviated. Many are typical English abbreviations, or short acronyms for often-used phrases. Distinct from prosigns and commercial codes Morse code abbreviations are not the same as prosigns. Morse abbreviations are composed of (normal) textual alpha-numeric character symbols with normal Morse code inter-character spacing; the character symbols in abbreviations, unlike the delineated character groups representing Morse code prosigns, are not "run together" or concatenated in the way most prosigns are formed. Although a few abbreviations (such as for "dollar") are carried over from former commercial telegraph codes, almost all Morse abbreviations are ''not'' commercial codes. From 1845 until well into the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
