Coffee Society
Durham (Dunholm O.E.) as a Northumbrian learning settlement originates with its Cathedral; founded in 995 AD as part of a Benedictine monastery. Monks maintained libraries and created an intellectual hub for the English speaking peoples. Fast forward a millennium and we find "DU Coffee Society" which describes itself as a welcoming space for students to learn about coffee making, latte art and each other.
Radio 300
United States educational settlements have one of the largest radio networks in the world; much of it funded with public money. During today's colloquium we limit our break down to, (1) Security and maintenance personnel radio, (2) Broadcast and student radio. We do not cover content issues; though we cover the technology that supports those content enterprises and the emergence of electromagnetic spectrum as the foundation of the Internet of (Small) Things.
Radio Transmission Power & Frequency Allocation
Why are there at least ten publicly funded radio stations receivable in a 75 mile radius up and down the I-94/I-75 corridor in Lower Peninsula Michigan -- all of them domiciled in public universities? Today at 16:00 UTC we explore signal strength standards and implications of gaps and overlaps from a public safety standpoint.
Global Positioning System: A Generation of Service to the World
Major Ben Calhoon, Chief of the Positioning, Navigation and Timing Branch within the Space Operations Division of Headquarters Air Force discusses the astonishing speed at which the world has accepted the global positioning system as the central element in time and space identification and measurement.
Quadrivium: Autumn
Educational settlements are where people come to feel at home in beautiful surroundings. The stack informing the beauty of these "cities-within-cities" changes 100 to 1000 times per day globally. Titles are time-sensitive, copyright protected and land in public law. We monitor the action continuously to formulate response to public consultations. Topics appear on our CALENDAR and explored every day at 16:00 UTC. Recommend refresh of this web page once or twice to see timeliest information.
Campus Low-Power-Transmitters
The electromagnetic spectrum is the most heavily regulated form of energy on earth. In the USA Carrier Current stations and Campus Radio stations do not require a license to set up and operate. A carrier current station consists of an AM radio frequency signal on a frequency between 535 and 1705 kHz injected into a power line. They are governed by 47 CFR Sections 15.207(c), 15.209(a), and 15.221 of the Commission's rules and are accessible in the link provided here.
Current Issues & Recent Research
We examine the proposals for the 2028 National Electrical Safety Code; including our own. Public comment on proposed changes will be received until March 24th. The 2026 National Electrical Code which has recently been released for public use (public input on the 2029 revision will be received until April 9, 2026). Next Tuesday we prepare proposals for Technical Committee CMP-2.
Fire Alarm & Signaling Code
There are hundreds of fire alarm shops, and thousands of licensed fire alarm technicians in the education communities guided by this core title in the NFPA catalog. For athletic facilities (such as large stadiums and gymnasiums) we take particular interest in Chapter 24 requirements for Emergency Communication Systems in enclosed and open air spaces. Public comment on the First Draft of the 2028 Revision will be received until June 3, 2026.
Hunting for Radio Frequency Interference
Amy Nordrum, Associate Editor for IEEE Spectrum, joins an expert on a hunt for radio frequency interference; an important journey since much of legacy radio communication will still be available if the world wide web is not.
