**[[Q code]] and [[prosigns for Morse code]] are used in [[amateur radio]], aviation, and [[marine radio]]. They provide specific abbreviations for concepts related to aviation, shipping, RTTY, radiotelegraph, and amateur radio.<ref>{{cite web |url=http://cbradiosource.com/archives/q_codes.pdf |title=Q Codes |publisher=CB Radio Source |access-date=2010-01-23 |url-status=dead |archive-url=https://web.archive.org/web/20140814025822/http://cbradiosource.com/archives/q_codes.pdf |archive-date=2014-08-14 }}</ref> In [[radiotelegraph]] operation, a Q code is often shorter,<ref name=Qcode_10code>Ten-codes require transmission of three prefix characters "10-" and two numbers, so five characters, on top of which digits and punctuation are all long sequences in Morse (5–6 dits or dahs). Letters are all short sequences in Morse (1–4 dits or dahs), so the prefix "Q" and two letters is fewer characters and shorter code sequences.</ref> and provides codes standardized by meaning in all languages – essential for international [[shortwave]] radio communications.
**[[Z code]]s are used for military radio communications [[NATO]] countries, and like Q codes are standardized across languages.
