The renewal application can be submitted no earlier than 90 days prior to the expiration date of the license. To complete a manual renewal of your license the FCC Form 601 (Main Form and/or associated schedules) is required. If you do not have an FCC Registration Number (FRN), FCC form 160 will also be required for a manual filing. Applications that require fees will need form 159. The purpose of the filing will either be Renewal Only "RO" or Renewal/Modification "RM". These forms can be obtained at FCC Forms
Renewal Only will be selected to renew an existing license that has not expired and where no changes in the license are being requested. Completing a Renewal Only you would only need to complete the 601 main form and form 159 if your application requires a fee.
Renewal/Modification would be used to renew an existing authorization, Special Temporary Authorization (STA), or developmental authorization and request a change in the conditions of that authorization, (including requesting a waiver). Completing a Renewal/Modification you would use 601 main form and schedules D & H for modifying technical data. (NOTE: Some radio services modifying technical information require frequency coordination through a Land Mobile Frequency Coordinator.)
Electronic filers would utilize the Universal Licensing System (ULS)
