#Licencia para disc cover 3 license#

The requirement that a station maintain a main studio within a station's primary coverage area or within a maximum distance of the community of license originated in an era in which stations were legally required to generate local content and the majority of a station's local, non-network programming was expected to originate in one central studio location. Policy and regulatory issues Nominal main studio requirements The former requirement to (in most cases) maintain an official main studio within 25 miles of the community's geographic center was discontinued in December 2017 when the regulation was amended. Other current requirements include providing a local telephone number in the community's calling area (or else a toll-free number). One example is the requirement for stations to identify themselves, by call sign and community, at sign-on, sign-off, and at the top of every hour of operation. The Federal Communications Commission (FCC) makes other requirements on stations relative to their communities of license these requirements have varied over time.

This electric field contour is called the 'principal community contour'. In the United States, the Communications Act of 1934 requires that 'the Commission shall make such distribution of licenses, frequencies, hours of operation, and of ower among the several States and communities as to provide a fair, efficient, and equitable distribution of radio service to each of the same.' The Federal Communications Commission interprets this as requiring that every broadcast station 'be licensed to the principal community or other political subdivision which it primarily serves.' For each broadcast service, the FCC defines a standard for what it means to serve a community for example, commercial FM radio stations are required to provide a field strength of at least 3.16 millivolts per meter (mV/m) over the entire land area of the community, whereas non-commercial educational FM stations need only provide a field strength of 1 mV/m over 50% of the community's population.
