Amateur Radio and Innovation in Telecommunications Technology AMATEUR RADIO AND INNOVATION IN TELECOMMUNICATIONS TECHNOLOGY by Kevin William Lloyd McQuiggin B.Sc., Simon Fraser University, 1983 THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF ARTS in the School of Communication ã Kevin William Lloyd McQuiggin 2001 SIMON FRASER UNIVERSITY November, 2001 All rights reserved.

Approval Name: Kevin William Lloyd McQuiggin Degree: Master of Arts Title of thesis: Amateur Radio and Innovation in Telecommunications Technology Examining Committee: Chair: Adjunct Professor Adam Holbrook, School of Communication Committee Chair Associate Professor Peter Anderson Senior Supervisor School of Communication Dr. Richard Smith Assistant Professor School of Communication Mr. Nigel Bell External Examiner Industry Canada, Surrey, British Columbia ii Abstract Throughout its history, amateur radio has made significant contributions to science, industry, and the social services. The economic and social benefit derived from amateur radio research has founded new industries, built economies, empowered nations, and saved lives. Amateur radio represents a unique research and development (R&D) environment that cannot be duplicated in the labs or research parks of either industry or the government. Existing at the intersection of the social, economic, cultural and scientific spheres, amateur radio leverages this position to invent and innovate from a unique perspective. Many now-commonplace communication technologies have their genesis in amateur radio. However, the amateur radio service, or more specifically, the portion of the electromagnetic spectrum allocated to the activity, is under extreme pressure from the telecommunications industry. Recent exponential growth in commercial wireless communication systems has taxed existing commercial spectrum allocations, and industry is eager for expansion. Amateur radio spectrum is threatened. Ironically, many of the communication technologies used by these firms were initially developed within the field of amateur radio. To justify their quest for additional spectrum, industry lobbyists portray amateur radio as an anachronism, and characterize amateur bands, particularly in the UHF and microwave region, as underutilized. On the contrary, innovative communications research within the hobby is alive and well, and many of these new amateur projects utilize the higher-frequency bands sought after by industry. There iii is commercial interest in some of the new technologies currently under development within amateur radio, and amateur radio continues to contribute to the state of the radio art. Therefore, amateur radio must be supported by government and the telecommunications industry it helped create, so that it may continue to innovate and serve as a source of creativity for both technological and social change as we move forward into the twenty-first century. iv Dedication To My Wife, Laura Purcell-McQuiggin v Acknowledgments I would like to acknowledge the assistance of the following individuals in my research and in the preparation of this thesis.

This monograph conducts a historical study of the Army Amateur Radio System, the predecessor to the Military Auxiliary Radio System (MARS). MARS is primarily known for its performance during the Vietnam conflict in providing morale communications for US service personnel. In 2009, the Department of Defense changed the MARS mission to support homeland security functions by using MARS to provide backup emergency communications to local, state, and federal authorities. Viewed as a new direction for MARS, the responsibility of providing emergency communications is the same mission that was ably conducted by the Army Amateur Radio System prior to the United States entry into World War II.

I. Introduction RM-11831 cures ongoing deficiencies that the ARRL and FCC have ignored since the late 1990s. Adoption of RM-11831 would remove existing rule ambiguities to ensure that all data transmissions in amateur radio have a readily available decoder for public use and eavesdropping, so that the public and other amateur operators can “read the mail” and learn about the hobby while intercepting any data signal for meaning over the air. As shown here in my reply to comments, RM-11831 would vastly improve the effectiveness of ACDS transmissions in emergency situations by making all data “open” for others to hear and react to, as required in 13-1918.

  • Amateur Satellite Frequency Coordination Request1
    Amateur Satellite Frequency Coordination Request — Page 1 AMATEUR SATELLITE FREQUENCY COORDINATION REQUEST1 1. Amateur-satellite service. Amateur stations meet the requirements of the radio regulations2, RR 1.56. and 1.57. RR 1.56 amateur service: A radiocommunication service for the purpose of self- training, intercommunication and technical investigations carried out by amateurs, that is, by duly authorized [licensed] persons [individual natural people] interested in radio technique solely with a personal aim [for themselves] and without pecuniary interest [compensation]. (NOTE: Explanatory terms in brackets are not part of the treaty text.) RR 1.57 amateur-satellite service: A radiocommunication service using space stations on earth satellites for the same purposes as those of the amateur service. Before asking for help from IARU with frequency coordination in the amateur-satellite service, make sure that your proposed operation meets the treaty requirements. NOTE: “Without pecuniary interest” means that you may accept free will donations of goods and services, that is, with nothing required in return. You may not sell services or data to anyone for any reason. Ultimately, the decision of whether the proposed operation is appropriate for the amateur- satellite service rests with your country’s administration (your national telecommunication regulator). Therefore, before sending your frequency coordination request to IARU, we suggest that you consult with your administration to determine whether the amateur-satellite service or another radiocommunication service is appropriate for your operation. 2. Self coordination. For over 100 years, amateur radio operators have maintained an effective tradition of self-regulation. Amateurs are expected to coordinate their use of frequencies.
