                              NOTICE OF VIOLATION

   Released: April 16, 2007

   By the District Director, Denver Office, Western Region, Enforcement
   Bureau:

    1. This is a Notice of Violation ("Notice") issued pursuant to Section
       1.89 of the Commission's Rules, to Nextel License Holdings 4, Inc.
       ("Nextel"), licensee of radio station WPOH340 in Englewood, Colorado.

    2. On February 27, 2007, in response to a complaint of interference, an
       agent of the Enforcement Bureau's Denver Office, using signal strength
       direction finding techniques, located the source of interference to an
       amplifier used in conjunction with a local specialized mobile service
       ("SMR") system. Subsequent on/off testing of the bi-directional
       amplifier ("BDA"), located at the Veolia Transit Facility in
       Englewood, Colorado, determined that it was the interfering source.
       The agent observed the following violation:

     a. 47 C.F.R. S 1.903(a): "Stations in the Wireless Radio Service must be
        used and operated only in accordance with the rules applicable to
        their particular service as set forth in this title and with a valid
        authorization granted by the Commission under the provisions of this
        part, except as specified in the Section 1.903(b)." The BDA, owned
        and operated by Nextel, was emitting a signal on approximately
        814.2625 MHz, a frequency not authorized by the WPOH340 license.

    3. Pursuant to Section 403 of the Communications Act of 1934, as amended,
       and Section 1.89 of the Commission's Rules, Nextel must submit a
       written statement concerning this matter within 20 days of release of
       this Notice. The response must fully explain each violation, must
       contain a statement of the specific action(s) taken to correct each
       violation and preclude recurrence, and should include a time line for
       completion of pending corrective action(s). The response must be
       complete in itself and signed by a principal or officer of Nextel. All
       replies and documentation sent in response to this Notice should be
       marked with the File No. and NOV No. specified above, and mailed to
       the following address:

    5. The Privacy Act of 1974 requires that we advise you that the
       Commission will use all relevant material information before it,
       including any information disclosed in your reply, to determine what,
       if any, enforcement action is required to ensure compliance. Any false
       statement made knowingly and willfully in reply to this Notice is
       punishable by fine or imprisonment under Title 18 of the U.S. Code.
