  Sec.  90.689   Field strength limits.

   (a) For purposes of implementing  Sec.  Sec. 90.689 through 90.699, predicted 36 and
   40 dB µV/m contours shall be calculated using Figure 10 of  Sec. 73.699 of this
   chapter with a correction factor of âˆ’9 dB, and predicted 18 and 22 dB µV/m
   contours shall be calculated using Figure 10a of  Sec. 73.699 of this chapter
   with a correction factor of âˆ’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  Sec. 90.621(b),
   the requirements of  Sec. 90.621(b) shall prevail.
