NOTICE OF UNLICENSED OPERATION
Case Number: EB-FIELDNER-12-0003533
 Document Number:  W201332360003
On September 5, 2012, an agent from this office responded to a complaint concerning 
interference on the frequency 947.00 MHz to a licensed user in Traverse City, Michigan.  Using 
direction finding techniques, the agent determined that the source of the interference was 
unlicensed radio signals on 947.0 MHz that were from emanating from the main studio of Station 
WLDR-FM, Traverse City, Michigan, licensed to Great Northern Broadcasting System, Inc. 
(Great Northern).  Further investigation revealed that Great Northern was operating a studio-to-
transmitter link for Station WLDR-FM on 947.00 MHz.  The Commission’s records show that 
no license was issued for operation of a studio to transmitter link on 947.000 MHz at this 
location in Traverse City, Michigan.
Radio stations must be licensed by the FCC pursuant to 47 U.S.C. § 301.  You are hereby warned 
that operation of radio transmitting equipment without a valid radio station authorization 
constitutes a violation of the Federal laws cited above and could subject the operator to severe 
penalties, including, but not limited to, substantial monetary fines, in rem arrest action against 
the offending radio equipment, and criminal sanctions including imprisonment.  (see 47 U.S.C. 
§§ 401, 501, 503 and 510).
UNLICENSED OPERATION OF THIS STUDIO-TO-TRANSMITTER LINK MUST BE 
DISCONTINUED IMMEDIATELY.
You have ten (10) days from the date of this notice to respond with any evidence that you have 
authority to operate granted by the FCC.  Your response should be sent to the address in the

U.S.C. § 552a(e)(3), we are informing you that the Commission’s staff will use all relevant
