       Station KNIM872 in Philadelphia, Pennsylvania, alleging that a
       spurious emission on 469.25 MHz was causing harmful interference to
       Mobile Communications' repeater system. During the investigation, the
       agent monitored signal transmission activity on 469.25 MHz in

   accordance with the procedures outlined in S: 76.609(h) and shall be
   limited as follows: Less than and including 54 MHz, and over 216 MHz - 15
   micro-volts per meter, measured at 30 meters." At the
