                      NOTICE OF UNAUTHORIZED OPERATION AND

                    INTERFERENCE TO LICENSED RADIO STATIONS

   Case Number: EB-11-CG-0042

   Document Number: W201132320002

   On March 8, 2011, in response to a complaint of interference, an agent
   from the Enforcement Bureau's Chicago Office inspected Johnsburg High
   School, located at 2002 West Ringwood Road, Johnsburg, Illinois, and
   observed a radio transmitting device designed to jam licensed cellular
   radio transmissions in the 850 to 950 MHz and 1.700 to 2.100 GHz frequency
   bands as well as other licensed frequency bands in operation. During the
   inspection, Mr. Stanley Dostal admitted that the unit had been in
   operation at the time of the inspection.

   Persons operating or using radio transmitters must be licensed or
   authorized by the Commission, pursuant to section 301 of the
   Communications Act of 1934, as amended ("Act").   In addition, radio
   transmitting equipment must comply with the Commission's Rules ("Rules").
   Section 333 of the Act prohibits willful or malicious interference with
   any radio communications of any station licensed or authorized by or under
   the Act or operated by the United States Government.   In addition,
   section 302(b) of the Act, and section 2.803(a) of the Rules prohibit the
   manufacture, importation, marketing, sale or operation of devices
   deliberately designed to jam or disrupt wireless communications. The
   Commission has issued two Public Notices specifically stating that the
   sale and use of transmitters designed to prevent, jam or interfere with
   the operation of cellular and personal communications service ("PCS")
   telephones is unlawful.   Section 303(n) of the Act also authorizes agents
   of the Commission to inspect all radio installations to determine
   compliance with Commission rules.

   The operation of the devices utilized by you constitutes a violation of
   sections 333, 302(b), and 301 of the Act, as described above. Such
   operation may subject you to substantial monetary forfeitures, in rem
   arrest action against the offending radio equipment, and criminal
   sanctions including imprisonment.   Because unauthorized operation creates
   a danger of interference to important radio communications services, and
   may subject the operator to severe penalties, this notice emphasizes the
   importance of complying strictly with these legal requirement.

   UNAUTHORIZED OPERATION OF ANY RADIO TRANSMITTING DEVICE DESIGNED TO JAM
   RADIO COMMUNICATIONS MUST NOT RESUME.

   You may respond with any information you believe relevant to this warning
   within (10) days from the date of this warning. Your response should be
   sent to the address in the letterhead and reference the listed case
   number. Under the Privacy Act of 1974, 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.
