   its  authorized  power  for the routine testing and maintenance of its
   transmitting  system,  and  for  conducting  experimentation  under an
   experimental authorization, provided no interference is caused to other
   stations maintaining a regular operating schedule within such period.

   (b) No station licensed for “daytime” or “specified hours” of operation may
   broadcast any regular or scheduled program during this period.
