Sec. 73.31  Rounding of nominal power specified on applications.

    (a) An application filed with the FCC for a new station or for an 
increase in power of an existing station shall

specify nominal power rounded to two significant figures as follows:

                                                                        
------------------------------------------------------------------------
                                                                Rounded 
                                                                down to 
                      Nominal power (kW)                        nearest 
                                                                 figure 
                                                                  (kW)  
------------------------------------------------------------------------
Below 0.25...................................................      0.001
0.25 to 0.99.................................................       0.01
1 to 9.9.....................................................        0.1
10 to 50.....................................................          1
------------------------------------------------------------------------

    (b) In rounding the nominal power in accordance with paragraph (a) 
of this section the RMS shall be adjusted accordingly. If rounding 
upward to the nearest figure would result in objectionable interference, 
the nominal power specified on the application is to be rounded downward 
to the next nearest figure and the RMS adjusted accordingly.

 73.33  Antenna systems; showing required.

    (a) An application for authority to install a broadcast antenna 
shall specify a definite site and include full details of the antenna 
design and expected performance.
    (b) All data necessary to show compliance with the terms and 
conditions of the construction permit must be filed with the license 
application. If the station is using a directional antenna, a proof of 
performance must also be filed.
