Regulate Radio Release For Free

To help protect families the FCC requires that indecent programming and profane speech on broadcast TV or radio are only allowed between 10 p.m. and a.m., when it is unlikely that children are watching television.

To do so, you must obtain MIB's consent (Ministry of Information & Broadcasting, Govt. of India). Except for the MIB, no one else has the authority to grant this license. You can begin your broadcast on the frequency once you receive the WPC's final approval (Radio FM).

In the United States, radio is regulated by the Federal Communications Commission (FCC) and the National Telecommunications and Information Administration (NITA).

The FCC does impose certain restraints and obligations on broadcasters. Speech regulations are confined to specific topics, which usually have been identified by Congress through legislation or adopted by the FCC through full notice-and-comment rulemaking or adjudicatory proceedings.

Below this is reserved for television stations. Radio waves would interfere with television waves, hampering communications. However, the FCC will allow radio broadcasts to produce transmissions lower than 88.1 MHz if the carrier wave does not go farther than about 60 meters.

You're referring to MHz, the frequency band that reserved for public broadcast FM radio, the band varies between countries but it's usually 86 - 108MHz. Frequencies outside that spectrum are reserved for other services, for example those just above it are used for commercial aviation communications.

In the AM band, each AM station has a maximum bandwidth of 10 kHz, extending 5 kHz above and 5 kHz below the assigned center frequency. The AM band in the United States covers frequencies from 540 kHz up to 1700 kHz, in 10 kHz steps (540, 550, 560 ... 1680, 1690, 1700).
