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.
