Editing Varicode (section)

'''Varicode''' is a [[self-synchronizing code]] for use in [[PSK31]]. It supports all [[ASCII]] characters, but the characters used most frequently in English have shorter codes. The space between characters is indicated by a 00 sequence, an implementation of [[Fibonacci coding]].  Originally created for speeding up real-time keyboard-to-keyboard exchanges over low [[Bandwidth (computing)|bandwidth]] links, Varicode is freely available.<ref>{{cite web |author=Steven L Karty, N5SK |title=PSK31 Spec |publisher=ARRL Website |url=http://www.arrl.org/psk31-spec |accessdate=18 Dec 2010}}</ref><ref>{{cite web |title=PSK31: A New Radio-Teletype Mode |author=Peter Martinez, G3PLX |url=http://www.arrl.org/files/file/Technology/tis/info/pdf/x9907003.pdf |accessdate=28 Sep 2017}}</ref><ref>{{cite web |author=ITU Working Party 5A |title=ITU-R M.2034: Telegraphic Alphabet for Data Communication by Phase Shift Keying at 31 Baud in the Amateur and Amateur-Satellite Services. |publisher=International Telecommunication Union (approved Feb, 2013) |url=http://www.itu.int/rec/R-REC-M.5B22-0-201302-D/en |accessdate=21 Feb 2013}}</ref>
