Changing channels, even briefly, for the purpose of testing to resolve interference issues, requires compliance with FCC regulations and careful consideration of potential impacts on other stations and listeners. Here are some important points to consider:
- FCC Approval: Any channel change, even for testing purposes, must have prior approval from the FCC. This includes filing the necessary applications and receiving authorization before making any channel adjustments.
- Interference Concerns: While testing may help identify potential interference sources or solutions, it’s essential to ensure that the testing itself does not cause interference to other stations or services. FCC regulations prioritize the protection of existing stations from harmful interference.
- Consultation: It’s advisable to consult with an FCC specialist or engineer who can assist in conducting interference tests in a controlled and compliant manner. They can guide you through the necessary steps and procedures to minimize disruptions to your station and others.
- Temporary Operation: If the testing requires temporary operation on a different channel, ensure that you adhere to the temporary operating conditions and frequencies specified by the FCC.
- Documentation: Keep detailed records of all testing procedures, including the date, time, frequencies, and any observed interference or changes in station performance. This documentation can be valuable for FCC compliance and troubleshooting.
- Listener Notification: If your LPFM station serves a local audience, consider notifying your listeners in advance about any planned testing or channel changes to minimize disruption to their listening experience.
- Regulatory Prohibition: LPFM stations are explicitly prohibited from changing channels without first obtaining a granted construction permit from the FCC. Unauthorized channel changes are considered violations of Section 301 of the Communications Act and may result in potential fines
- Authorized Changes: LPFM stations can make certain changes to their facilities without prior authorization, as specified in §73.875(c) of the FCC Rules. These changes include antenna replacements, transmission line replacements, and changes in time share hours, provided that they adhere to specific conditions and file a modification of the license application within 10 days of making the change/
- Distance Separation Requirements: LPFM stations must also consider distance separation requirements, as outlined in §73.807, when contemplating a channel change. These requirements aim to protect full-service stations on co-channel, first- and second-adjacent channels. An interference showing may be required for second-adjacent channels.
- Construction Permits: If an LPFM station is granted a construction permit for a channel change, it is then authorized to “test” on the new channel. However, LPFM stations cannot operate on both their old and new facilities simultaneously.
- License to Cover: If the channel change proves to be successful, the LPFM station must file a License to Cover to inform the FCC of the change. Failure to do so may result in unauthorized operation if the construction permit lapses.
- Construction Permit Duration: Construction permits typically have a 3-year term. If LPFM stations continue to operate on the new facility without filing a License to Cover and the construction permit expires, it is considered unauthorized operation and may result in fines.
In summary, while testing to address interference issues is a valid approach, it must be conducted in accordance with FCC regulations and with careful consideration of potential impacts on other stations and listeners. Seeking guidance from FCC specialists or engineers is strongly recommended to ensure compliance and minimize disruptions.
