Teaching with Technology: a Proposal for Using Amateur Radio in the Classroom
DOCUMENT RESUME ED 378 943 IR 016 946 AUTHOR Newell, Peter R. TITLE Teaching with Technology: A Proposal for Using Amateur Radio in the Classroom. PUB DATE Dec 94 NOTE 29p.; Adapted from a paper submitted in partial fulfillment of class requirements for VTE 500, Contemporary Concepts in Vocational-Technical Education, Spring 1994, and published in the 1994 American Radio Relay League National Educational Workshop proceedings. A"AILLE FROMPeter R. Newell, 8226 Trevi Lane, Clay, NY 13041 ($10). PUB TYPE Viewpoints (Opinion/Position Papers, Essays, etc.) (120) Reports Evaluative/Feasibility (142) EDRS PRICE MF01/PCO2 Plus Postage. DESCRIPTORS *Communication (Thought Transfer); Educational Innovation; *Educational Radio; Educational' Technology; Elementary Secondary Education; Interdisciplinary Approach; Language Arts; Self Esteem; *Student Motivation; ''Teaching Methods; *Vocational Education IDENTIFIERS *Ham Radio ABSTRACT Amateur radio is a technology and activity that offers great potential when integrated into academic or vocational curricula. Programs with electrical, electronics, and electromechanical content can benefit from the use of amateur radio, and can also enhance language and communications skills. The biggest value of amateur radio may lie in its ability to enhance a student's motivation and self-esteem. In addition to its specific vocational and technical applications, amateur radio can assist in teaching basic skills and in reducing the isolation of students and teachers as it promotes interdisciplinary education and cultural awareness. Amateur radio is distinctly different from citizens band, as it is a noncommercial service. Ham operators do not need an electronics background, although technical knowledge and skills are helpful. Several examples of the educational use of amateur radio illustrate its potential for academic and vocational education. -

Federal Communications Commission April 27, 2019 445 F St. NW Washington, DC 20022 Subject: Reply Comments in RM-11831 Dear
Prof. Theodore (Ted) S. Rappaport, Ph.D, PE David Lee/Ernst Weber Professor of Electrical & Computer Engineering NYU WIRELESS Tandon School of Engineering New York University 9th Floor, 2 Metrotech Center Brooklyn, NY 11201 www.NYUWIRELESS.org Ph: 646 997 3403 [email protected] Federal Communications Commission April 27, 2019 445 F St. NW Washington, DC 20022 Subject: Reply Comments in RM-11831 Dear FCC and ARRL Officials: In my role as a wireless communications engineer and expert, a former Federal Communications Commission Technological Advisory Council member, a friend to the amateur radio community, a licensed amateur radio operator (N9NB), a Professional Engineer in Virginia and Texas, and a life member of the American Radio Relay League (ARRL), I file this reply regarding RM-11831 to reinforce why the FCC must urgently adopt this proposal in principle, in order to ensure data transparency in amateur radio and to eliminate the use of private email and secret file transfers that are currently being transmitted in the amateur radio spectrum. 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. -
A Century of WWV
Volume 124, Article No. 124025 (2019) https://doi.org/10.6028/jres.124.025 Journal of Research of the National Institute of Standards and Technology A Century of WWV Glenn K. Nelson National Institute of Standards and Technology, Radio Station WWV, Fort Collins, CO 80524, USA [email protected] WWV was established as a radio station on October 1, 1919, with the issuance of the call letters by the U.S. Department of Commerce. This paper will observe the upcoming 100th anniversary of that event by exploring the events leading to the founding of WWV, the various early experiments and broadcasts, its official debut as a service of the National Bureau of Standards, and its role in frequency and time dissemination over the past century. Key words: broadcasting; frequency; radio; standards; time. Accepted: September 6, 2019 Published: September 24, 2019 https://doi.org/10.6028/jres.124.025 1. Introduction WWV is the high-frequency radio broadcast service that disseminates time and frequency information from the National Institute of Standards and Technology (NIST), part of the U.S. Department of Commerce. WWV has been performing this service since the early 1920s, and, in 2019, it is celebrating the 100th anniversary of the issuance of its call sign. 2. Radio Pioneers Other radio transmissions predate WWV by decades. Guglielmo Marconi and others were conducting radio research in the late 1890s, and in 1901, Marconi claimed to have received a message sent across the Atlantic Ocean, the letter “S” in telegraphic code [1]. Radio was called “wireless telegraphy” in those days and was, if not commonplace, viewed as an emerging technology. -
Echolink Users Guide
EchoLink Users Guide Version 1.0 Affiliated Club EchoLink Internet Linking for Amateur Radio What is Echolink? EchoLink uses VoIP (Voice Over Internet Protocol) to allow licensed amateur Radio Operators to communicate with other Amateurs via the Internet. It is primarily a Windows based application and is offered free of charge at http://www.echolink.org. There is also a new EchoLinux and EchoMac available. Now available is an iPhone and Android app that can be used to con- nect to operators around the world while you are on the go. It was developed by Jonathan Taylor (K1RFD) in 2002 (He received Hamvention 2003 Special Achievement Award). The system allows reliable worldwide connections to be made between radio amateurs, greatly enhancing Amateur Radio's communications capabilities. In essence it is the same as other VoIP applications (such as Skype), but with the unique addition of the ability to link to an amateur radio station's trans- ceiver. Before using the system it is necessary for a prospective user's call sign to be validated. The EchoLink system requires that each new user provide positive proof of license and identity before his or her call sign is added to the list of validated users. EchoLink Users Guide Version 1.0 | 3 Modes EchoLink can be operated strictly between two computers connected to the Internet using the PC soundcard with Speakers and a Microphone. EchoLink can be interfaced to a standard FM transceiver as a “simplex link” from your home QTH. EchoLink can be interfaced to a VHF or UHF repeater for more coverage.
