They are not charged with operating at excessive power levels, only failure to have a current valid license..
Although the Station’s license was not formally cancelled until 2004,... Station had been operating without a valid instrument of authorization since its license expired on August 1, 1998. Even had Pennington filed a license renewal application at some time after expiration and prior to cancellation, the Station may still have been subject to potential forfeiture for not only failing to file a timely license renewal application, but also operating without a valid authorization. See e.g., Salmon River Communications, Inc., Memorandum Opinion and Order and Notice of Apparent Liability for Forfeiture, 26 FCC Rcd 14490, 14492 (MB 2011) ($13,000 forfeiture proposed for late-filing and unauthorized operation for more than five years after station's license expired).
