§ 73.840   Operating power and mode tolerances.

   The transmitter power output (TPO) of an LPFM station must be
   determined by the procedures set forth in § 73.267 of this part. The
   operating TPO of an LPFM station with an authorized TPO of more than
   ten watts must be maintained as near as practicable to its authorized
   TPO and may not be less than 90% of the minimum TPO nor greater than
   105% of the maximum authorized TPO. An LPFM station with an authorized
   TPO of ten watts or less may operate with less than the authorized
   power, but not more than 105% of the authorized power.
