When the electric grid and the internet are down and there is no cell service, radio can still work to help communities stabilize. Starting 2024 we will break down our coverage of the radio frequency technology standards used in educational settlements into into two categories:
Radio 300: Security and maintenance radio. These usually use a single radio channel and operate in a half-duplex mode: only one user on the channel can transmit at a time, so users in a user group must take turns talking. The radio is normally in receive mode so the user can hear all other transmissions on the channel. When the user wants to talk he presses a “push-to-talk” button, which turns off the receiver and turns on the transmitter; when he releases the button the receiver is activated again. Multiple channels are provided so separate user groups can communicate in the same area without interfering with each other.
Radio 400: Student radio. College radio stations are typically considered to be public radio radio stations in the way that they are funded by donation and grants. The term “Public radio” generally refers to classical music, jazz, and news. A more accurate term is community radio, as most staff are volunteers, although many radio stations limit staff to current or recent students instead of anyone from the local community. There has been a fair amount of drama over student-run radio station history; a topic we steer away from.
The Low Power FM radio service was created by the Commission in January 2000. LPFM stations are authorized for noncommercial educational broadcasting only (no commercial operation) and operate with an effective radiated power (ERP) of 100 watts (0.1 kilowatts) or less, with maximum facilities of 100 watts ERP at 30 meters (100 feet) antenna height above average terrain. The approximate service range of a 100 watt LPFM station is 5.6 kilometers (3.5 miles radius). LPFM stations are not protected from interference that may be received from other classes of FM stations.
We follow — but do not respond — to consultations on titles covering the use of radio frequencies for the Internet of Things. At the moment, most of that evolution happens at the consumer product level; though it is wise to contemplate the use of the electromagnetic spectrum during widespread and extended loss of broadband services.

We do not include policy specifics regarding the migration of National Public Radio beyond cultural content into political news; though we acknowledge that the growth of publicly financed radio domiciled in education communities is a consideration in the technology of content preparation informed by the Public Broadcasting Act of 1967.
We drill into technical specifics of the following:
Radios used for campus public safety and campus maintenance
Student-run campus radio stations licensed by the Federal Communications Commission as Low Power FM (LPFM)
Facilities for regional broadcast of National Public Radio operating from education communities
Off-campus transmission facilities such as broadcast towers.
Grounding, bonding, lightning protection of transmission and receiving equipment on buildings
Broadcast studio electrotechnologies
Radio technology is regulated by the Federal Communications Commission with no ANSI-accredited standards setting organizations involved in leading practice discovery and promulgation.

Dutch student radios (known as studentenzenders or campus radios) are typically non-commercial, educational broadcasting initiatives run by universities or student associations. They operate primarily as cable radio stations (kabelradio) distributed via campus or university cable networks, rather than over-the-air FM/AM transmissions. This avoids the need for expensive ether frequency licenses and aligns with their limited, non-public reach. Over-the-air broadcasting is rare for student radios due to regulatory hurdles and costs, but if pursued, it falls under general broadcasting rules.
Standards are governed by the Dutch Media Act (Mediawet), enforced by the Dutch Media Authority (Commissariaat voor de Media, CvdM) for content and permissions, and the Dutch Authority for Digital Infrastructure (Rijksinspectie Digitale Infrastructuur for technical aspects. For cable distribution, no broadcast license is required if confined to private/university networks, but equipment must comply with EU directives.

We sweep through the world’s three major time zones; updating our understanding of the literature at the technical foundation of education community safety and sustainability in those time zones 24 times per day. We generally eschew “over-coding” web pages to sustain speed, revision cadence and richness of content as peak priority. We do not provide a search facility because of copyrights of publishers and time sensitivity of almost everything we do.
Our daily colloquia are typically doing sessions; with non-USA titles receiving priority until 16:00 UTC and all other titles thereafter. We assume policy objectives are established (Safer-Simpler-Lower-Cost, Longer-Lasting). Because we necessarily get into the weeds, and because much of the content is time-sensitive and copyright protected, we usually schedule a separate time slot to hammer on technical specifics so that our response to consultations are meaningful and contribute to the goals of the standards developing organization and to the goals of stewards of education community real assets — typically the largest real asset owned by any US state and about 50 percent of its annual budget.
1. Leviathan. We track noteworthy legislative proposals in the United States 118th Congress. Not many deal specifically with education community real assets since the relevant legislation is already under administrative control of various Executive Branch Departments such as the Department of Education.
We do not advocate in legislative activity at any level. We respond to public consultations but there it ends.
We track federal legislative action because it provides a stroboscopic view of the moment — the “national conversation”– in communities that are simultaneously a business and a culture. Even though more than 90 percent of such proposals are at the mercy of the party leadership the process does enlighten the strengths and weakness of a governance system run entirely through the counties on the periphery of Washington D.C. It is impossible to solve technical problems in facilities without sensitivity to the zietgeist that has accelerated in education communities everywhere.

Abstract. The analysis presented in this paper indicates that the FM radio spectrum is underutilized in the areas of the continental United States that have a population of 100000 or less. These locations have vacant FM radio spectrum of at least 13 MHz with sufficient spectrum spacing between adjacent FM radio channels. The spectrum spacing provides the required bandwidth for data transmission and provides enough bandwidth to minimize interference introduced by neighboring predicted and unpredicted FM radio stations and other low-power short-range Internet of Thing (IoT) devices. To ensure that low-power short-range IoT devices maintain reliable communications vacant radio spectrum, such as the FM radio spectrum in these areas, will need to be used through cognitive radio.
The term “podcast” is a combination of “iPod,” Apple’s portable media player, and “broadcast.” It originated in the early 2000s when individuals began creating audio content specifically designed for download and playback on portable media players, including the iPod. Over time, the concept has evolved, and podcasts are now a popular and diverse form of digital media covering a wide range of topics, including news, education, entertainment, and more. The key feature of a podcast is its on-demand nature, allowing listeners to access content at their convenience.
We examine the proposals for the 2028 National Electrical Safety Code; including our own. The 2026 National Electrical Code where sit on CMP-15 overseeing health care facility electrical issues should be released any day now. We have one proposal on the agenda of the International Code Council’s Group B Committee Action Hearings in Cleveland in October. Balloting on the next IEEE Gold Book on reliability should begin.

Recap of the May meetings of the Industrial & Commercial Power Systems Conference in Las Vegas. The conference ended the day before the beginning of the 3-day Memorial Day weekend in the United States so we’re pressed for time; given all that happened.
We can use our last meeting’s agenda to refresh the status of the issues.
We typically break down our discussion into the topics listed below:
Codes & Standards:
While IAS/I&CPS has directed votes on the NEC; Mike is the only I&CPS member who is actually submitting proposals and responses to codes and standards developers to the more dominant SDO’s — International Code Council, ASHRAE International, UL, ASTM International, IEC & ISO. Mike maintains his offer to train the next generation of “code writers and vote getters”
Performance-based building premises feeder design has been proposed for the better part of ten NEC revision cycles. The objective of these proposals is to reduce material, labor and energy waste owed to the branch and feeder sizing rules that are prescriptive in Articles 210-235. Our work in service and lighting branch circuit design has been largely successful. A great deal of building interior power chain involves feeders — the network upstream from branch circuit panels but down stream from building service panel.
Our history of advocating for developing this approach, inspired by the NFPA 101 Guide to Alternative Approaches to Life Safety, and recounted in recent proposals for installing performance-based electrical feeder design into the International Building Code, appears in the link below:
Access to this draft paper for presentation at any conference that will receive it — NFPA, ICC or IEEE (or even ASHRAE) will be available for review at the link below:
NFPA 110 Definitions of Public Utility v. Merchant Utility
NFPA 72 “Definition of Dormitory Suite” and related proposals
Buildings:
Renovation economics, Smart contracts in electrical construction. UMich leadership in aluminum wiring statements in the NEC should be used to reduce wiring costs.
This paper details primary considerations in estimating the life cycle of a campus medium voltage distribution grid. Some colleges and universities are selling their entire power grid to private companies. Mike has been following these transactions but cannot do it alone.
Variable Architecture Multi-Island Microgrids
District energy:
Generator stator winding failures and implications upon insurance premiums. David Shipp and Sergio Panetta. Mike suggests more coverage of retro-fit and lapsed life cycle technicals for insurance companies setting premiums.
Reliability:
Bob Arno’s leadership in updating the Gold Book.
Mike will expand the sample set in Table 10-35, page 293 from the <75 data points in the 1975 survey to >1000 data points. Bob will set up meeting with Peyton at US Army Corps of Engineers.
Reliability of merchant utility distribution systems remains pretty much a local matter. The 2023 Edition of the NESC shows modest improvement in the vocabulary of reliability concepts. For the 2028 Edition Mike submitted several proposals to at least reference IEEE titles in the distribution reliability domain. It seems odd (at least to Mike) that the NESC committees do not even reference IEEE technical literature such as Bob’s Gold Book which has been active for decades. Mike will continue to propose changes in other standards catalogs — such as ASTM, ASHRAE and ICC — which may be more responsive to best practice assertions. Ultimately, improvements will require state public utility commission regulations — and we support increases in tariffs so that utilities can afford these improvements.
Mike needs help from IEEE Piscataway on standard WordPress theme limitations for the data collection platform.
Mike will update the campus power outage database.
Healthcare:
Giuseppe Parise’s recent work in Italian power grid to its hospitals, given its elevated earthquake risk. Mike’s review of Giuseppe’s paper:
Mike and David Shipp will prepare a position paper for the Harvard Healthcare Management Journal on reliability advantages of impedance grounding for the larger systems.
The Internet of Bodies
Forensics:
Giuseppe’s session was noteworthy for illuminating the similarity and differences between the Italian and US legal system in handling electrotechnology issues.
Mike will restock the committee’s library of lawsuits transactions.
Ports:
Giuseppe updates on the energy and security issues of international ports. Mike limits his time in this committee even though the State of Michigan has the most fresh water international ports in the world.
A PROPOSED GUIDE FOR THE ENERGY PLAN AND ELECTRICAL INFRASTRUCTURE OF A PORT
Other:
Proposals to the 2028 National Electrical Safety Code: Accepted Best Practice, exterior switchgear guarding, scope expansion into ICC and ASHRAE catalog,
Apparently both the Dot Standards and the Color Books will continue parallel development. Only the Gold Book is being updated; led by Bob Arno. Mike admitted confusion but reminded everyone that any references to IEEE best practice literature in the NFPA catalog, was installed Mike himself (who would like some backup help)
Mike assured Christel Hunter (General Cable) that his proposals for reducing the 180 VA per-outlet requirements, and the performance-base design allowance for building interior feeders do not violate the results of the Neher-McGrath calculation used for conductor sizing. All insulation and conducting material thermal limits are unaffected.
Other informal discussions centered on the rising cost of copper wiring and the implications for the global electrotechnical transformation involving the build out of quantum computing and autonomous vehicles. Few expressed optimism that government ambitions for the same could be met in any practical way.
Are students avoiding use of Chat GPT for energy conservation reasons? Mike will be breaking out this topic for a dedicated standards inquiry session:
To what degree does the endless and, frankly shameless, on-air fundraising by an organization with widely tolerated bias constitute de facto political fundraising for the Democratic Party? In Southeastern Michigan — in less than a 50 mile region — you can hear the same NPR “content” from six different universities: Ann Arbor, Ypsilanti, Toledo, Detroit, East Lansing, and Flint.

National Public Radio follows guidelines and best practices when conducting fundraising campaigns, but they’re not so much strict “rules” as they are principles and standards upheld by NPR and its member stations. Here are some common practices and considerations:
Transparency: NPR and its member stations are typically transparent about their funding needs and where the money goes. They often provide detailed breakdowns of their budgets and expenses.
Ethical Solicitation: Fundraising efforts should be conducted ethically and in accordance with NPR’s values. This means avoiding misleading tactics and being honest about the need for funding.
Listener Support: NPR often emphasizes the importance of listener support in funding their programming. They encourage individuals to contribute at various levels, often with incentives like member benefits.
Corporate Sponsorship: NPR also receives funding from corporate sponsors, “but they are careful to maintain editorial independence.” Sponsored content is clearly labeled, and NPR maintains strict guidelines to ensure that sponsors do not influence editorial decisions.
Member Stations: NPR member stations across the country conduct their own fundraising campaigns, often in conjunction with national NPR campaigns. These stations rely heavily on listener support and may have their own guidelines and practices.
Regulatory Compliance: NPR and its member stations must comply with relevant laws and regulations governing fundraising, including those related to nonprofit organizations and broadcasting.
Stewardship: NPR and its member stations typically prioritize stewardship of donor funds, ensuring that donations are used effectively and efficiently to support their mission and programming.
While there may not be hard and fast rules for NPR fundraising, adherence to these principles helps maintain trust with listeners and supporters.
To become a National Public Radio (NPR) member station or broadcaster, certain criteria must be met. NPR is a mission-driven organization that partners with independently owned and operated public radio stations across the United States to deliver its programming. Here are the typical criteria for becoming an NPR member station:
Nonprofit Status: NPR member stations must be nonprofit organizations, often affiliated with universities, community organizations, or governmental bodies.
Broadcast License: Stations must hold a valid broadcast license issued by the Federal Communications Commission (FCC) in the United States. This license authorizes the station to broadcast on a specific frequency within a designated geographic area.
Commitment to NPR’s Mission: Member stations are expected to share NPR’s mission of providing high-quality, non-commercial programming that serves the public interest. This includes delivering news, cultural content, and educational programming to their local communities.
Financial Stability: Stations must demonstrate financial stability and viability to ensure they can fulfill their commitments to NPR and their local communities over the long term.
Technical Requirements: Stations must meet certain technical requirements to ensure they can receive and broadcast NPR programming effectively. This includes having appropriate transmission equipment and meeting FCC regulations for broadcast quality and coverage.
Membership Dues: Member stations are required to pay annual membership dues to NPR, which help support NPR’s operations and programming.
Compliance with NPR Policies: Stations must adhere to NPR’s policies and guidelines regarding programming standards, ethics, and editorial independence.
Community Engagement: NPR values stations that are actively engaged with their local communities, including through outreach, events, and partnerships with local organizations.
Programming Commitment: Member stations are expected to broadcast a significant portion of NPR programming, including flagship shows like “Morning Edition” and “All Things Considered,” as well as other NPR-produced content.
Commitment to Diversity, Equity, and Inclusion: NPR values diversity in its member stations and encourages stations to reflect the diversity of their communities in their programming and staffing.
Overall, becoming an NPR member station involves a combination of legal, financial, technical, and cultural considerations, all aimed at supporting NPR’s mission of providing high-quality public radio programming to audiences across the United States.
A significant portion of NPR member stations are associated with universities or colleges. These stations are often operated by the educational institution’s media departments or affiliated broadcasting organizations. They serve as valuable training grounds for students studying journalism, communications, broadcasting, and related fields.
While the exact number of NPR member stations associated with universities or colleges may vary over time, it’s safe to say that a substantial portion of the network falls into this category. Many universities and colleges across the United States operate their own radio stations, and a portion of these stations choose to affiliate with NPR to access its programming and resources.
National Public Radio (NPR) member stations are permitted to transmit from facilities supported by federally funded colleges or universities, as many are licensed as noncommercial educational (NCE) stations under the Federal Communications Commission (FCC). These stations, often operated by or affiliated with public colleges and universities, meet FCC requirements for NCE licenses, which allow them to broadcast educational and cultural programming without commercial advertisements.
Key Points:NCE Licensing: NPR member stations are typically licensed as NCE stations, which can be owned or operated by nonprofit entities, including public colleges and universities. These institutions often receive federal funding, and their facilities (e.g., campus buildings or transmission equipment) can be used for broadcasting.
Funding Structure: Stations affiliated with colleges or universities may receive funding from the institution, listener contributions, corporate underwriting, and federal grants via the Corporation for Public Broadcasting (CPB). Federal funding, while a small portion (e.g., ~10% of public radio revenue), is often channeled through CPB to support station operations.
Examples: Many NPR member stations, such as WBEZ (operated by Chicago Public Media but affiliated with educational institutions) or KUT (operated by the University of Texas), transmit from university-supported facilities. Approximately half of NPR’s member stations are affiliated with colleges, sometimes operating directly from campus facilities.
FCC Regulations: The FCC allows NCE stations to broadcast from such facilities as long as they adhere to noncommercial guidelines, prohibiting promotional advertisements for for-profit entities while permitting donor acknowledgments.
Impact of Federal Funding Cuts: Recent reductions in federal funding for public media, as reported in 2025, may strain these stations, particularly those reliant on university support, as budget-strapped institutions face additional financial pressures.
There are no explicit FCC restrictions preventing NPR stations from using federally funded college or university facilities, provided they comply with NCE regulations.
During today’s colloquium we audit the literature that sets the standard of care for mechanical engineering design, construction operations and maintenance of campus district energy systems — typically miles (kilometers) of large underground pipes and wires that characterize a district energy system. Topically, Mechanical 400 deals with energy systems “outside” or “between” buildings; whereas Mechanical 200 deals with energy systems within an individual building envelope.
A campus district energy system is a centralized heating and cooling network that supplies thermal energy to multiple buildings within a defined area, such as a college or university campus. The system generates steam, hot water, or chilled water at a central plant, which is then distributed through an underground network of pipes to individual buildings for space heating, domestic hot water, and air conditioning. By consolidating energy production and distribution, campus district energy systems can achieve significant energy and cost savings compared to individual building systems, as well as reduce greenhouse gas emissions and improve reliability and resiliency of the energy supply.

It is a large domain and virtually none of the organizations listed above deal with district energy systems outside their own (market-making) circle of influence. As best we can we try to pull together the peak priorities for the real asset managers and engineers who are responsible for these system.
* Building services engineers are responsible for the design, installation, operation and monitoring of the technical services in buildings (including mechanical, electrical and public health systems, also known as MEP or HVAC), in order to ensure the safe, comfortable and environmentally friendly operation. Building services engineers work closely with other construction professionals such as architects, structural engineers and quantity surveyors. Building services engineers influence the architectural design of building, in particular facades, in relation to energy efficiency and indoor environment, and can integrate local energy production (e.g. façade-integrated photovoltaics) or community-scale energy facilities (e.g. district heating). Building services engineers therefore play an important role in the design and operation of energy-efficient buildings (including green buildings, passive houses and zero energybuildings. uses. With buildings accounting for about a third of all carbon emissions] and over a half of the global electricity demand, building services engineers play an important role in the move to a low-carbon society, hence mitigate global warming.
