[[Amateur radio]] operators began experimenting with packet radio in 1978, when—after obtaining authorization from the Canadian government—Robert Rouleau, VE2PY; Bram Frank, VE2BFH; Norm Pearl, VE2BQS; and Jacques Orsali, VE2EHP<ref>I wrote the code for the demo on May 31st 1978 at the M.A.R.C. meeting in Montreal</ref> of the Montreal Amateur Radio Club [[Montreal]], [[Quebec]], began experimenting with transmitting [[ASCII]] encoded data over [[VHF]] amateur radio frequencies using homebuilt equipment.<ref>Rouleau, Robert and Hodgson, Ian (1981).

In 1989, Lockhart was inducted by the Canadian Amateur Radio Federation (CARF, now [[Radio Amateurs of Canada]]), as its First Member of the Canadian Amateur Radio Hall of Fame (CARHOF) for his outstanding contribution to the development of Amateur Packet Radio Communications.<ref>https://www.rac.ca/carhof/canadian-amateur-radio-hall-of-fame-1989-doug-lockart-ve7apu/</ref>  In 2003, Rouleau was inducted into [[CQ Amateur Radio]] magazine's hall of fame for his work on the Montreal Protocol in 1978.<ref>{{cite web|title=The CQ Amateur Radio Hall of Fame|publisher=[[CQ Amateur Radio]]|date=June 2007|url=http://www.cq-amateur-radio.com/AmateurRadioHofFMay2907.pdf|access-date=2009-05-02|archive-url=https://web.archive.org/web/20081203062737/http://www.cq-amateur-radio.com/AmateurRadioHofFMay2907.pdf|archive-date=2008-12-03|url-status=dead}}</ref>

Not long after this activity began in Canada, amateurs in the US became interested in packet radio. In 1980, the United States [[Federal Communications Commission]] (FCC) granted authorization for United States amateurs to transmit ASCII codes via amateur radio.<ref name=chron>{{cite web| last=Mendelsohn |first=Alex |url=http://www.n1fd.org/bulls/2000/0005/dxrx.html |title=Amateur Packet – A Brief Chronology: Phase 1 (1970–1986) |access-date=2009-08-09 |archive-url=https://web.archive.org/web/20010129134100/http://www.n1fd.org/bulls/2000/0005/dxrx.html |archive-date=2001-01-29}} See ''FCC Gives The Nod'' and ''Making Modifications''</ref> Repeaters may be designed for amateur packet radio, these are dubbed "digipeaters". The first known amateur packet radio activity in the US occurred in [[San Francisco]] during December 1980, when a packet repeater was put into operation on [[2 meters]] by [[Hank Magnuski]] KA6M, and the Pacific Packet Radio Society (PPRS).<ref>Kenney, Larry [http://www.choisser.com/packet/part01.html "Introduction to Packet Radio – Part 1"], "A Short History – How it all began".

Many groups of amateur radio operators interested in packet radio soon formed throughout the country including the Pacific Packet Radio Society (PPRS) in [[California]], the [[Tucson Amateur Packet Radio Corporation]] (TAPR) in [[Arizona]] and the Amateur Radio Research and Development Corporation (AMRAD) in [[Washington, D.C.]]<ref>American Radio Relay League (2008).

By 1983, TAPR was offering the first TNC available in kit form. Packet radio started becoming more and more popular across [[North America]] and by 1984 the first packet-based [[bulletin board system]]s began to appear. Packet radio proved its value for emergency operations following the [[Aeroméxico Flight 498|crash of an Aeromexico]] airliner in a neighborhood in [[Cerritos, California]], in August 1986. Volunteers linked several key sites to pass text traffic via packet radio which kept voice frequencies clear.
