NOTICE OF UNLICENSED OPERATION
Case Number:  EB-FIELDWR-17-00025207
The Denver Office (Denver Office) of the Federal Communications Commission’s (FCC’s or 
Commission’s) Enforcement Bureau (Bureau) received a complaint from the San Luis Valley 
Regional Airport (SLVRA or Airport) concerning possible interference to its aeronautical 
advisory station (Unicom) frequency, 122.8 MHz. On September 19, 2017, Agents from the 
Denver Office investigated the matter on-scene, observing operation by SLVRA employees and 
aircraft on frequency 122.8 MHz at the airport. The Commission’s records show that there is no 
valid authorization for operation on 122.8 MHz at this location in Alamosa, Colorado.   
Radio stations operating on many frequencies, including 122.8 MHz,
1
must be licensed by the 
FCC pursuant to Section 301 of the Communications Act of 1934, as amended (Act).
2
The only 
exception to this licensing requirement is for certain transmitters using or operating at a power 
level or mode of operation that complies with the standards established in Part 15 of the 
Commission’s rules.
3
The radio station operating on 122.8 MHz exceeded the maximum 
permitted Part 15 power level for non-licensed devices.  Thus, this station is operating in 
violation of Section 301 of the Act.
4
  
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 RADIO STATION 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 
letterhead and reference the listed case and document number.  Under the Privacy Act of 1974,

with FCC Rules.  This will include any information that you disclose in your reply.
You may contact this office if you have any questions.
