§  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.
