For decades, no actual transmissions were made using Lincos; it remained largely a theoretical exercise, until [[Canadians|Canadian]] [[astrophysicist]]s [[Yvan Dutil]] and [[Stéphane Dumas (astrophysicist)|Stéphane Dumas]], working at the [[Defence Research and Development Canada|Canadian Defense Research Establishment]], created a noise-resistant coding system for messages aimed at [[Communication with extraterrestrial intelligence|communicating with extraterrestrial civilizations]].{{Citation needed|reason=Reference needed describing the coding and its relation to Lincos|date=February 2017}} In 1999, the astrophysicists encoded a message in Lincos and used the [[Yevpatoria RT-70 radio telescope]] in [[Ukraine]] to beam it towards close stars. This is known as [[Cosmic Call]]. The experiment was repeated (using other close stars as target) in 2003. The message was a series of pages describing some basic mathematics, physics and astronomy.<ref>Webb, Stephen ''Where Is Everybody?'', Praxis Publishing Ltd, 2002, p. 260</ref> The Dutil–Dumas experiment was promoted by an organization called ''Encounter 2001''.<ref>{{Cite web |url=http://www.encounter2001.com |archive-url=https://web.archive.org/web/20150918042825/http://www.encounter2001.com/ |archive-date=2015-09-18 |url-status=dead |title=Encounter 2001, promoters of the experiment by Dutil and Dumas which encoded a message in Lincos and beamed it towards close stars.}}</ref>

Some [[Communication with extraterrestrial intelligence|researchers]] have explored the similar issues in communicating with intelligent animals such as [[cetacea]]ns.{{Citation needed|reason=Reliable source needed|date=February 2017}} Lincos messages (even if sent by pulses of sound rather than radio) are complex and need to reach the most patient, logically oriented members of the target species. A far simpler approach aimed at average members of a species can cover numbers, >, <, =, +, -, and time.{{citation needed|date=March 2022}}
