Modification Application

Request A Modification To An Existing FCC License

We process all applications where an FCC license is required. We file all types of Part 87, 88, 90, 95 & 101 FCC applications.

You would modify a license to change technical or legal parts of an existing license. For example, adding a frequency, increasing the power of an antenna, or changing the regulatory status of a license are all things that are filed on a modification application.

Changes to administrative information on your license such as mailing address, phone number, or e-mail address are handled by filing an Administrative Update.

Please click the “e-file” button below, complete the data form and submit.

Narrowbanding FAQ’s

Do you meet the FCC Narrowanding mandate which went into effect on January 1, 2013?

Narrowband Exempt Paging-Only Frequencies

Do you have a Paging-Only license? Are you narrowband exempt? Are you sure?

According to the FCC, there are 14 paging-only frequencies that are exempt from having to comply with the Narrowband Mandate.

Identified in FCC Rule Section §90.20 Public Safety and §90.35 Business/Industrial, the following frequencies have assignment limitations identifying them as one way paging-only channels authorized for a 25 kHz bandwidth. Please note the exceptions!

Public Safety Pool:

  • 152.0075
  • 157.4500
  • Exception: 163.2500, 150.775, 150.790 – Available for one-way paging operations for Medical Radio Communications Systems, these frequencies are shared with the Federal Government and are NOT exempt. They must now be narrowband!

Business/Industrial Pool:

  • 152.480
  • Exception: 154.625 – Does not have FCC 90.35(c) limitation (29), stating, “This frequency will be authorized a channel bandwidth of 25kHz” and therefore is NOT exempt and must now be narrowband!
  • 157.740
  • 158.460
  • 462.750
  • 462.775
  • 462.800
  • 462.825
  • 462.850
  • 462.875
  • 462.900
  • 462.925
  • 465.000

Federal License Management offers a FCC Compliance Management Service to verify if your current one-way paging frequencies are actually narrowband exempt, if your license(s) is/are up to date, and if the information on your license is in compliance with FCC rules. The fee is $150, which is waived for License Management service subscribers.

Narrowbanding – FAQs

What licensing bands were affected by the narrowband mandate?

All public safety and business industrial land mobile radio systems operating in the VHF 150-174 MHz and UHF 421-470 MHz radio bands must now be operating at 12.5 kHz channel bandwidths or narrower, or at an equivalent throughput efficiency for which 25 kHz exclusive use channels may be retained.

The FCC removed the narrowband requirement for T-Band licensees in the 470-512 MHz band in April of 2012.

What happens if we failed to move to narrowband operations?

Your license is now in violation of the FCC Rules and you are subject to FCC enforcement action, which may include a monetary fine, admonishment or loss of your license.

What happened when a narrowbanding application was properly completed and sent to a frequency advisory committee (FAC) too close to the January deadline to be properly certified and transmitted to the FCC?

The FCC agreed that each FAC will prepare a list of call signs for which narrowbanding applications have been received on or before December 31, 2012, but not filed with the FCC; these lists will be transmitted to the commission and to all other FACs by January 3, 2013. This FCC-approved process supports narrowbanding objectives and reasonably accommodates licensees that presumptively have narrowband-compliant equipment in place, even though they waited to file their license modification applications.

How can I quickly determine if my license is narrowband compliant?

If the Emissions Designator shown on your license begins with 4K, 7K, 8K or 11K, then your license is compliant. If your Emissions Designator starts with a number greater than 11K, more than likely 20K or 16K, you are not in compliance and must change your emission.

Do I have to change frequencies when I go narrowband?

Adding or changing your emission to narrowband does not require a frequency change.

Do we have to convert to digital when we convert to narrowband operation?

There is no digital requirement when you migrate to narrowband.

Is the FCC still accepting and granting waiver requests seeking an extension of time to comply with the required narrowbanding mandate?

The FCC is still accepting narrowband waiver requests, however, such filings must include an explanation as to why they are being filed after the deadline and a defined, expedited path toward compliance.

After we convert our radio system and licenses to 12.5 kHz narrowband, can we keep the 25 kHz spectrum we were once authorized to use?

No. When a licensee updates their system to comply with the narrowbanding mandate and upgrades to either a 12.5 kHz or equivalent analog or digital technology, the amended license reflects the original channel assignment, but the amount of authorized bandwidth will be reduced. There are, however, certain digital technologies that comply with the narrowband spectrum efficiency requirement permitting the continued use of 25 kHz authorized channels.

Is there a mandate for licensees to migrate to VHF and UHF systems to 6.25 kHz channel bandwidths?

No, the FCC is not presently engaged in any rule making proceeding that would require licensees to migrate their systems to a 6.25 kHz or equivalent efficiency at this time.

Are paging-only frequencies exempt from Narrowbanding?

Yes. However, there are only (14) paging-only frequencies the FCC recognizes as being exempt.

  • Public Safety Pool – 152.0075 and 157.4500
  • Business/Industrial Pool – 152.480, 157.740, 158.460, 462.750, 462.775, 462.800, 462.825, 462.850, 462.875, 462.900, 462.925 and 465.000

In the case of a user who neglects to properly narrowband their equipment, could a wireless sales/service provider be held liable for programming radios with frequencies that the customer is no longer authorized to use?

Yes. FCC Rule 90.427, Precautions Against Unauthorized Operation covers this issue. EWA has drafted for use by wireless sales/service providers a Customer Radio Programming Release Form that can be used in this situation. It should be noted however, that the form only serves the purpose of drawing your customers’ attention to the fact that they need licenses for the devices you are maintaining. The document itself does not remove your responsibility, but it helps to alert the customer.

Does a a tower owner have any responsibility to the FCC for tower lessee occupants who choose not to comply with the narrowbanding mandate and continue to transmit non-compliant signals?

No. The tower owner is not responsible.

Will 25 kHz non-compliant systems receive interference from narrowband licensees?

Interference will most likely result from both primary co-channel and adjacent channel narrowband systems.

Was Narrowbanding designed to provide more spectrum to Public Safety?

No, narrowbanding is intended to ensure more efficient use of the spectrum when all licensees have transitioned to narrowband.

What does Equivalent Efficiency mean?

If your radios meet any of the following criteria, then they meet the 12.5 kHz equivalent efficiency requirement:

  • One voice path in a 12.5 kHz channel
  • Two voice paths in a 25 kHz channel
  • Data operations on channels greater that 12.5 kHz must employ data rates greater than 4.8 kbps per 5.25 kHz channel, such as 19.2 kbps per 25 kHz channel
