Sec.  76.616   Operation near certain aeronautical and marine emergency radio
frequencies.

   (a) The transmission of carriers or other signal components capable of
   delivering peak power levels equal to or greater than 10^−5watts at any
   point in a cable television system is prohibited within 100 kHz of the
   frequency 121.5 MHz, and is prohibited within 50 kHz of the two frequencies
   156.8 MHz and 243.0 MHz.

   (b) At any point on a cable system from 405.925 MHz to 406.176 MHz analog
   transmissions are prohibited from delivering peak power levels equal to or
   greater than 10^−5watts. The transmission of digital signals in this range
   is limited to power levels measured using a root-mean-square detector of
   less  than 10^−5watts in any 30 kHz bandwidth over any 2.5 millisecond
   interval.
