Silent AM and FM Broadcast Stations (2024)

The Telecommunications Act of 1996 provided for the expiration of broadcast licenses as a matter of law upon a station's failure to operate for 12 consecutive months. The Commission still has discretion to terminate licenses under existing revocation and cancellation policies in situations in which the automatic expiration provisions do not apply.

A list of currently silent stations may be generated by visiting the LMS search page, selecting the "Facility Search", and inputting the desired station type(s), e.g. "FM Translator" or "Full Power FM" or "Low Power FM") and status "Licensed and Silent".

List users should be aware that silent stations may not be available for sale, and that the FCC does not maintain any information about stations that may be available for purchase.

Deleted or Cancelled Stations. When a station loses its license, that license is not immediately available to other interested parties. In the case of AM stations, the potential applicant must await the next auction/application filing window period. When a commercial FM station is deleted or cancelled, the allotment (or placeholder) remains, but no application for a new station construction permit can be filed until the next auction/application filing window. In both services, commercial new station facilities are auctioned, as mandated by the Telecommunications Act of 1996.

For FM noncommercial educational stations, and low power FM stations, there is no allotment record remaining after a station license cancellation, but any potential applicant cannot file a new station construction permit application until the next application filing window period opens for such stations. New FM noncommercial educational permittees, as well as new station LPFM permittees, are selected using a point system when competing applications are filed.

Notifications and requests for Special Temporary Authority. Stations that go silent mist file a notice of suspension of operations request in the LMS application filing system (see the LMS Help Center), within 10 days of ceasing operation. The filing should include an attachment with a brief explanation of the reason for ceasing operation and include a projected date for the station's return to licensed operation (if possible). Short periods of discontinued operation (less than 10 days) need not be reported but should be entered in the station's log (see 47 CFR Section 73.1820). Tower obstruction lighting must be maintained without interruption during all periods of silence to protect general aviation.

If the station's silent period is expected to last beyond 30 days, Special Temporary Authority is necessary (see 47 CFR Section 73.1635 and Emergency Antennas, Silent Stations, Special Temporary Authority (STA) for Broadcast Services). Stations must submit the Silent Station STA request in the LMS application filing system (see the LMS Help Center) and clearly explain in an attachment to the application the circ*mstances surrounding the request. After review, the staff may grant Special Temporary Authority for a period not exceeding 180 days, but extensions may be approved upon the submission of a new STA extension request.

It is imperative that every licensee of a silent station notify the Commission through the LMS application system when broadcast operations resume.

Silent AM and FM Broadcast Stations (2024)

FAQs

Why do FM stations sound better than AM stations? ›

Because electrical signals can affect a carrier wave's amplitude, AM radio tends to emit more static in comparison to FM radio. FM radio also offers greater bandwidth, resulting in more nuanced sound quality.

What does it mean when a radio station is silent? ›

In telecommunications, radio silence or emissions control (EMCON) is a status in which all fixed or mobile radio stations in an area are asked to stop transmitting for safety or security reasons.

Why won't my car radio pick up stations? ›

One of the most common causes of poor car radio reception is a poor antenna connection. If the antenna cable is poorly seated in your head unit, or any of the connections are loose, worn, or corroded, you'll often find it difficult to tune into your favorite station.

Why are no radio stations working? ›

This can happen when your radio receives more than one signal. The second signal is picked up by the radio moments after the first. For example you receive one signal directly from the transmitter and another is being reflected off a nearby hill. Try moving the radio or tuning to a different frequency.

What are the disadvantages of AM radio? ›

The downside to AM broadcasting is that it is more susceptible to interference than other transmission methods, and the audio quality of AM radio is at a lower fidelity than the others: FM, digital, satellite, HD, Internet, etc.

Why do we prefer FM over AM? ›

In FM systems, the power of the transmitted signal is proportional to the amplitude of the unmodulated carrier signal and it is constant. Therefore, FM is usually more power-efficient than AM systems.

What is the point of radio silence? ›

In military operations, radio silence is usually a command issued from above, as out of fear that a signal might be intercepted by an enemy. And maritime radio operators, for example, might follow a directive of radio silence in order to hear faint distress signals.

How long can a radio station be silent? ›

Broadcast regulations

In the U.S., prolonged dead air, such as a shutdown occurring without permission, is an actionable offense that can result in fines from the Federal Communications Commission (FCC). According to the FCC, a station has a 30-day limit for going silent without approval.

What are the FCC dark stations? ›

According to the U.S. Federal Communications Commission (FCC), a radio or television station is considered to have gone dark or silent if it is to be off the air for thirty days or longer.

Why is my AM radio reception poor? ›

However, brick, cement block, stucco, aluminum, or metal-sided buildings almost always cause AM reception problems (unless, of course, you have a lot of windows which do not usually block AM radio waves). These types of building materials block and prevent a majority of AM radio waves from reaching your radio.

Why do I keep losing my radio stations? ›

If the battery runs down, the data is lost. In addition, if the radio is moved to a new location, or signal strength is very low, some radios will automatically erase existing pre-sets and scan for new stations.

Why is my AM FM radio not picking up stations? ›

If your radio is a portable, try moving the aerial to different angles. You could also try a different position in the room. Window sills and high shelves are good places for radios; avoid putting them close to radiators or electronic equipment such as computers, mobile/cordless phones or TV sets.

Why doesn't AM radio work anymore? ›

Due to the nature of AM signals, or 'Amplitude Modulation', any interference on the broadcast frequency becomes noise that completely blocks out the signal.

Why is my AM radio not working in my car? ›

Antenna problems.

If your car's antenna is broken, disconnected, or not properly installed, it can affect radio signal reception. Outdated software Just like computers and smartphones, modern car radios also require software updates. Failure to update the radio software can lead to compatibility issues.

Why is the noise performance of FM better than AM? ›

Frequency Modulation

The radio signals have large bandwidth than AM radio signals, which helps to offer much better sound quality. Frequency modulation also enables to transmit stereo signals.

Why is FM superior than AM? ›

In addition FM waves give better sound reproduction. With an FM broadcast, slight changes in amplitude don't matter at all -- since the audio signal is conveyed through changes in frequency, the FM receiver can just ignore changes in amplitude. The result: better sound reproduction.

Why does FM radio sound richer than AM radio? ›

"FM, which stands for Frequency Modulation, has better sound quality due to higher bandwidth. Also, the way the audio is encoded for FM makes it less sensitive to interference from electrical activity from storms or electrical devices than AM.

Why does AM radio sound different to FM? ›

The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.
