§  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.
