   Michael Herring

   Philadelphia, PA

                         NOTICE OF UNLICENSED OPERATION

   Case Number: EB-10-PA-0142

   Document Number: W201032400008

   On May 19, 2010, the Philadelphia Office received information that
   interference was being caused to critical Global Positioning System
   ("GPS") navigation signals in the downtown area of Philadelphia. Using
   mobile direction finding techniques, agents determined that the
   interference was coming from Apartment # 550 at 3131 Walnut Street in
   Philadelphia, Pennsylvania and was causing interference to the GPS
   navigation signals on 1575.42 MHz on May 19, 2010 and May 20, 2010. Agents
   further determined that the interference was caused by a radio
   transmitting device  designed to jam Global Positioning System ("GPS
   Jammers") transmissions that Michael Herring was operating from Apartment
   # 550 at 3131 Walnut Street, Philadelphia, Pennsylvania. The use of a GPS
   Jammer is strictly prohibited. Mr. Herring admitted to operating the
   device and voluntarily relinquished the device to the agents.

   Persons operating or using radio transmitters must be licensed or
   authorized by the FCC, pursuant to Section 301 of the Communications Act
   of 1934, as amended. In addition, radio transmitting equipment must comply
   with FCC rules.  GPS Jammers are intentional radiators and operate in
   frequency bands used for GPS, which are within the restricted frequency
   bands listed in Section 15.205(a) of the Rules. The purpose of GPS Jammers
   is to block or interfere with radio communications that are conveying
   navigation information. Such use is prohibited by Section 333 of the Act,
   which states that "[n]o person shall willfully or maliciously interfere
   with or cause interference to any radio communications of any station
   licensed or authorized by or under this Act or operated by the United
   States Government." A GPS Jammer operates in restricted frequency bands,
   intentionally interferes with radio communications, is not eligible for
   FCC certification, and use of a GPS jammer is strictly prohibited.

   The operation of a  GPS jammer by Michael Herring constitutes a violation
   of Sections 333 and 301 of the Act, as described above,  and future
   operation of a GPS jammer may subject Michael Herring  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 warning emphasizes the importance of complying strictly with these
   legal requirements.


   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 the Communications Act and FCC Rules. This will include
   any information that you disclose in your reply.

   restricted bands, from transmitters operating outside the restricted
