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:
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

Standards for radio broadcast coverage can vary depending on factors like location, broadcasting technology, and regulatory requirements. Here’s a general list covering various aspects:
These standards are often enforced by governmental regulatory agencies, industry organizations, and professional associations to ensure the quality, integrity, and safety of radio broadcast coverage.

The frequency differences between public safety radio and public broadcasting radio are mainly due to their distinct purposes and requirements.
NFPA 1930 is in a custom cycle due to the Emergency Response and Responder Safety Document Consolidation Plan (consolidation plan) as approved by the NFPA Standards Council. As part of the consolidation plan, NFPA 1930 is combining Standards NFPA 1801, NFPA 1802, NFPA 1932, NFPA 1937, and NFPA 1962.
Firefighter radio communication faces several special technical challenges due to the nature of the environment they operate in and the criticality of their tasks. Here are some of the key challenges:

Sie strahlt vor Freude über ihre Auszeichnung – TH-Alumna Melanie Klaus. Für ihre Bachelorarbeit im Bereich Erneuerbare Energien wurde sie vom Solarenergieförderverein Bayern geehrt. In ihrer Bachelorarbeit im Studiengang Elektro- und Informationstechnik untersuchte sie das Zusammenspiel von Wind- und Solarenergie und den Nutzen, der sich hieraus für die regenerative Energieerzeugung erzielen lässt. Untersucht wurde also die Nutzung der natürlichen Kombination von Wind und Sonne für die Energieerzeugung. Um die Rentabilität dieser Einspeisekombination zu ermitteln, hat Melanie Klaus ein Software-Tool entwickelt, welches zur Planung und Simulation abgestimmter Photovoltaik-Wind-Kombinationen dient und bereits für die Errichtung einer Photovoltaik-Anlage zu einem Windpark eingesetzt wird. |
