Sec.  73.153  Field strength measurements in support of applications or 
evidence at hearings.

    In the determination of interference, groundwave field strength 
measurements will take precedence over theoretical values, provided such 
measurements are properly taken and presented. When measurements of 
groundwave signal strength are presented, they shall be sufficiently 
complete in accordance with Sec.  73.186 to determine the field strength 
at 1 mile in the pertinent directions for that station. The antenna 
resistance measurements required by Sec.  73.186 need not be taken or 
submitted.
