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.

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.
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.

Design, construction, operation and maintenance of environmental air, piping and drainage systems is one of the largest cost centers in education facilities. We find subtle tradeoffs between fire safety, energy conservation and indoor air quality goals. With solid data and enlightened debate which include the user-interest (the final fiduciary in the education facility industry, for example) those tradeoffs are reconciled by technical committees administered by three ANSI-accredited standards developers:
[NFPA 90A] shall cover construction, installation, operation, and maintenance of systems for air conditioning and ventilating, including filters, ducts, and related equipment, to protect life and property from fire, smoke, and gases resulting from fire or from conditions having manifestations similar to fire.
[Explanation A.1.1] An air duct system has the potential to convey smoke, hot gases, and flame from area to area and to supply air to aid combustion in the fire area. For these reasons, fire protection of an air duct system is essential to safety to life and the protection of property. However, an air duct system’s fire integrity also enables it to be used as part of a building’s fire protection system. Guidance for the design of smoke-control systems is provided in NFPA 92, Standard for Smoke Control Systems. Pertinent information on maintenance is provided in Annex B. Maintenance of fire dampers, ceiling dampers, smoke dampers, and combination fire/smoke dampers requirements can be found in NFPA 80, Standard for Fire Doors and Other Opening Protectives, and NFPA 105, Standard for Smoke Door Assemblies and Other Opening Protectives.
The original University of Michigan codes and standards advocacy enterprise spoke loud and clear about duct smoke detector application, control signaling and maintenance requirements from the user point of view. Owing to the re-organization we missed the 2018 revision but we are now recovering from where we left off for the 2021 revision.
The First Draft Report for the 2021 edition is linked below:
NFPA 90A is heavily referenced in an interlocking matrix of related fire safety consensus products but it is not very lengthy document. We include it on the standing agenda of our periodic Mechanical and Prometheus Bound teleconference. See our CALENDAR for the next online meeting.

We are waiting for the link to the Complete Monograph for the Group A cycle in which one of our proposals (Chapter 27 Electrical) will be heard at the April 2023 Committee Action Hearings in Orlando.
Superceded:
Because of the larger, disruptive concepts usually require more than one revision cycle — i.e. 3 to 9 years — it is wise to track those ideas in the transcripts of public hearings on the revisions. For example, the ICC Group A Committee Action Hearings were completed (virtually) in May 2021. The complete monograph of proposals is linked below:
Proposals for the 2024 IMC revision will be accepted until January 7, 2024. We maintain this title among our core titles during our periodic Mechanical teleconferences. See our CALENDAR for the next online meeting; open to everyone.
Clean the chicken, put it in a large pot and cover it with cold water. Bring the water to boil.
Add the chicken wings, onions, sweet potato, parsnips, turnips and carrots. Boil about 1 and a half hours. Remove fat from the surface as it accumulates.
Add the parsley and celery. Cook the mixture about 45 min. longer.
Remove the chicken. The chicken is not used further for the soup. (The meat makes excellent chicken parmesan.)
Put the vegetables in a food processor until they are chopped fine or pass through a strainer. Both were performed in the present study.
Add salt and pepper to taste.
