   The Detroit Office received information regarding an unlicensed marine
   base radio station operating on the frequency 156.8 MHz in Muskegon,
   Michigan. On August 29, 2007, an agent from this office inspected the
   radio station and confirmed that TowBoatUS Muskegon was operating a
   station on 156.8 MHz from 1434 Montgomery Avenue, Muskegon, Michigan. The
   Commission's records show that no license was issued for your radio at
   this location on 156.8 MHz in Muskegon, Michigan.

   Radio stations must be licensed by the FCC pursuant to 47 U.S.C. S: 301.
   You are hereby warned that operation of radio transmitting equipment
   without a valid radio station authorization constitutes a violation of 47
   U.S.C. S: 301 and could subject the owner of this illegal operation 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. S:S: 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, 5 U.S.C.
   S: 552a(e)(3), we are informing you that the Commission's staff will use
   all relevant material information before it to determine what, if any,
   enforcement action is required to ensure your compliance with FCC Rules.
   This will include any information that you disclose in your reply.
