  §  90.689   Field strength limits.

   (a) For purposes of implementing § § 90.689 through 90.699, predicted 36
   and 40 dBµV/m contours shall be calculated using Figure 10 of § 73.699
   of this chapter with a correction factor of −9 dB, and predicted 18 and
   22 dBµV/m contours shall be calculated using Figure 10a of § 73.699 of
   this chapter with a correction factor of −9 dB.

   (b) The predicted or measured field strength at any location on the
   border of the EA-based service area for EA licensees must not exceed 40
   dBuV/m unless all bordering EA licensees agree to a higher field
   strength. In the event that this standard conflicts with the EA
   licensee's obligation to provide co-channel protection to incumbent
   licensees pursuant to § 90.621(b), the requirements of § 90.621(b) shall
   prevail.
