§ 90.745   Phase I licensee service areas.

   (a) A Phase I licensee's service area shall be defined by the predicted 38
   dBu  service  contour  of its authorized base station or fixed station
   transmitting  on  frequencies in the 220-221 MHz band at its initially
   authorized  location  or at the location authorized in accordance with
   § § 90.751, 90.753, 90.755 and 90.757 if the licensee has sought modification
   of its license to relocate its initially authorized base station. The Phase
   I  licensee's predicted 38 dBu service contour is calculated using the
   F(50,50) field strength chart for Channels 7-13 in § 73.699 (Fig. 10) of this
   chapter, with a 9 dB correction factor for antenna height differential, and
   is  based on the authorized effective radiated power (ERP) and antenna
   height-above-average-terrain  of  the licensee's base station or fixed
   station.  Phase  I  licensees  are permitted to add, remove, or modify
   transmitter  sites  within  their  existing service area without prior
   notification to the Commission so long as their predicted 38 dBu service
   contour is not expanded. The incumbent licensee must, however, notify the
   Commission within 30 days of the completion of any changes in technical
   parameters or additional stations constructed through a minor modification
   of its license. Such notification must be made by submitting the appropriate
   FCC form and must include the appropriate filing fee, if any. These minor
   modification applications are not subject to public notice and petition to
   deny requirements or mutually exclusive applications.

   (b) Phase I licensees holding authorizations for service areas that are
   contiguous and overlapping may exchange these authorizations for a single
   license, authorizing operations throughout the contiguous and overlapping
   service areas. Phase I licensees exercising this license exchange option
   must submit specific information for each of their external base station
   sites.
