                              NOTICE OF VIOLATION

                                                  Released: December 21, 2011

   By the District Director, San Francisco 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 Luxor Cab Co., Inc. ("Luxor"),
       licensee of radio station WQMA933 in San Francisco, California.

    2. On August 18, 2011, in response to a complaint from the San Mateo
       County Fire Department (SMCFD) concerning interference to their land
       mobile units operating on 154.040 MHz, agents of the Enforcement
       Bureau's San Francisco Office used mobile direction finding techniques
       to locate the malfunctioning repeater owned by Luxor. The repeater was
       causing interference to SMCFD mobile radio communications in San
       Mateo, California. The agents located Luxor's repeater near Wolfback
       Ridge Rd, 37'0 51' 03.0" north latitude and 122'0 29' 51.0" west
       longitude, southwest of Sausalito, California, and observed the
       following violations:

     a. 47 C.F.R. S: 90.403(e): "Licensees shall take reasonable precautions
        to avoid causing harmful interference." At the time of the
        investigation, agents determined that WQMA933 data transmission
        signal on 152.300 MHz generated spurious emissions on 154.010 and
        154.040 MHz causing interference to SMCFD land mobile units on
        154.040 MHz.

     b. 47 C.F.R. S: 90.433(c): "The station licensee shall be responsible
        for the proper operation of the station at all times and is expected
        to provide observations, servicing and maintenance as often as may be
        necessary to ensure proper operation." At the time of the
        investigation, agents inspected Luxor's radio transmitter and
        determined that the installed power amplifier for WQMA933 was
        malfunctioning and emanating spurious emissions causing interference
        to SMCFD mobile radios.

    3. Pursuant to Section 308(b) of the Communications Act of 1934, as
       amended, and Section 1.89 of the Commission's Rules, Luxor, 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
       Luxor. 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:
