§  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 § 73.186 to determine the field strength at
   1 mile in the pertinent directions for that station. The antenna
   resistance measurements required by § 73.186 need not be taken or
   submitted.
