Section 74.1251, Technical and Equipment Modifications

Section 74.1251 requires licensee to certify compliance with technical requirements upon replacement of a transmitter that can be accomplished without FCC approval. Additionally, Section 74.1251 requires licensees to notify FCC in writing of changes in the primary FM station being transmitted. The certification provides to prospective users information of the modified equipment. If no such information exists, any future problems could prove difficult to solve and could result in electronic frequency interference for long periods of time. The notification of changes in the primary FM station is used by FCC staff to keep records up-to-date and to ensure compliance with FCC rules and regulations.
