47 CFR § 101.65 - Termination of station authorizations.
In addition to the provisions of § 1.953 of this chapter, a site-based license will be automatically terminated in whole or in part without further notice to the licensee upon the voluntary removal or alteration of the facilities, so as to render the station not operational for a period of 30 days or more. A licensee is subject to this provision commencing on the date it is required to be providing service or operating under § 101.63. This provision is inapplicable to blanket authorizations to operate fixed stations at temporary locations pursuant to the provisions of § 101.31(a)(2). See § 101.305 for additional rules regarding temporary and permanent discontinuation of service.
