   station transmitters, however, the maximum rated transmitter power of a
   main transmitter stalled at an AM station shall be as follows:

   25 or 50 kW 50

   (c) A licensee may, without further authority or notification to the
   FCC, replace an existing main transmitter or install additional main
   transmitter(s) for use with the authorized antenna if the replacement
   or additional transmitter(s) has been verified for compliance. Within
   10 days after commencement of regular use of the replacement or
   additional transmitter(s), equipment performance measurements, as
   prescribed for the type of station are to be completed.

   Note to paragraph ( c ): Pending the availability of AM broadcast
   transmitters that are approved or verified for use in the 1605-1705 kHz
   band, transmitters that are approved or verified for use in the
   535-1605 kHz band may be utilized in the 1605-1705 kHz band if it is
   shown that the requirements of §  73.44 have been met. Verification or
