Radio Transmission Power & Frequency Allocation

Why are there at least 10 publicly funded radio stations receivable in a 75 mile radius (back and forth, up and down) the I-94/I-75 corridor of Michigan — all of them domiciled in public universities?  These stations also receive revenue from other non-profit organizations, unending funding drives and private advertising from multinational financing organizations such as Schwab, Fidelity and other for-profit corporations.   Most of them purchase their “content” from the same source; reflecting the same large government bias seen across the entire nation; concentrated in college towns with spotty intellectual history.

Within an approximate 50 mile radius of the University of Michigan, five national public radio stations are receivable:

WUOM University of Michigan Ann Arbor

WEMU Eastern Michigan University

WDET Wayne State University

WKAR Michigan State University

WGTE University of Toledo

Move 25 miles to the northwest and two more are receivable:

WVGR Michigan Public Radio

WLNZ Landing Community College

Move 25 miles northeast and three more are receivable

WFUM University of Michigan Flint

WMUK Western Michigan University

WAUS Andrews University

Education communities provide a large market for recreational and therapeutic water technology suppliers.  Some of the larger research universities have dozens of pools including those in university-affiliated healthcare facilities.  Apart from publicly visible NCAA swimming programs there are whirpools in healthcare facilities and therapeutic tubs for athletes in other sports.   Ownership of these facilities requires a cadre of conformance experts to assure water safety.

NSF International is one of the first names in this space and has collaborated with key industry stakeholders to make pools, spas and recreational water products safer since 1949.   The parent document in its suite is NSF 50 Pool, Spa and Recreational Water Standards  which  covers everything from pool pumps, strainers, variable frequency drives and pool drains to suction fittings, grates, and ozone and ultraviolet systems.  

The workspace for this committee is linked below:

Joint Committee on Recreational Water Facilities

(Standards Michigan is an observer on this and several other NSF committees and is the only “eyes and ears” for the user interest; arguably the largest market for swimming pools given their presence in schools and universities.)

There are 14 task groups that drill into specifics such as the following:

The meeting packet is confidential to registered attendees.  You may communicate directly with the NSF Joint Committee Chairperson, Mr. Tom Vyles (admin@standards.nsf.org) about arranging direct access as an observer or technical committee member.   

Almost all ANSI accredited technical committees have a shortage of user-interests (compliance officers, manufacturers and installers usually dominate).  We encourage anyone in the education facility industry paying the bill for the services of compliance officers, manufacturers and installers to participate. 

We maintain this title on the standing agenda of our Water and Sport colloquia.  See our CALENDAR for the next onine meeting; open to everyone.

Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard

Thunderstorm | Shelter (Building: 30/30 Rule)

The standards for delaying outdoor sports due to lightning are typically set by governing bodies such as sports leagues, associations, or organizations, as well as local weather authorities. These standards may vary depending on the specific sport, location, and level of play. However, some common guidelines for delaying outdoor sports due to lightning include:

  1. Lightning Detection Systems: Many sports facilities are equipped with lightning detection systems that can track lightning activity in the area. These systems use sensors to detect lightning strikes and provide real-time information on the proximity and severity of the lightning threat. When lightning is detected within a certain radius of the sports facility, it can trigger a delay or suspension of outdoor sports activities.
  2. Lightning Distance and Time Rules: A common rule of thumb used in outdoor sports is the “30-30” rule, which states that if the time between seeing lightning and hearing thunder is less than 30 seconds, outdoor activities should be suspended, and participants should seek shelter. The idea is that lightning can strike even when it is not raining, and thunder can indicate the proximity of lightning. Once the thunder is heard within 30 seconds of seeing lightning, the delay or suspension should be implemented.
  3. Local Weather Authority Guidelines: Local weather authorities, such as the National Weather Service in the United States, may issue severe weather warnings that include lightning information. Sports organizations may follow these guidelines and suspend outdoor sports activities when severe weather warnings, including lightning, are issued for the area.
  4. Sports-Specific Guidelines: Some sports may have specific guidelines for lightning delays or suspensions. For example, golf often follows a “Play Suspended” policy, where play is halted immediately when a siren or horn is sounded, and players are required to leave the course and seek shelter. Other sports may have specific rules regarding how long a delay should last, how players should be informed, and when play can resume.

It’s important to note that safety should always be the top priority when it comes to lightning and outdoor sports. Following established guidelines and seeking shelter when lightning is detected or severe weather warnings are issued can help protect participants from the dangers of lightning strikes.

Noteworthy: NFPA titles such as NFPA 780 and NFPA 70 Article 242 deal largely with wiring safety, informed by assuring a low-resistance path to earth (ground)

There are various lightning detection and monitoring devices available on the market that can help you stay safe during thunderstorms. Some of these devices can track the distance of lightning strikes and alert you when lightning is detected within a certain radius of your location. Some devices can also provide real-time updates on lightning strikes in your area, allowing you to make informed decisions about when to seek shelter.

Examples of such devices include personal lightning detectors, lightning alert systems, and weather stations that have lightning detection capabilities. It is important to note that these devices should not be solely relied upon for lightning safety and should be used in conjunction with other safety measures, such as seeking shelter indoors and avoiding open areas during thunderstorms.
