FCC Part 73 rules for AM, FM and digital radio

Description

The electronic Code of Federal Regulations provides access to 47 CFR Part 73, covering radio broadcast services. The part includes AM, FM, digital audio broadcasting, low-power FM and general broadcast station rules. For radio engineers in the United States, the material is essential for understanding technical limits, service classes, operating requirements and regulatory constraints. It is also useful to equipment suppliers and consultants working with FCC-authorized facilities. The eCFR is regulatory rather than voluntary standardization, but it functions as a primary technical rules reference for U.S. broadcast radio.
