Sec.  27.1206   Geographic Service Area.

   (a) The Geographic Service Area (GSA) is either:

   (1) The area for incumbent site-based licensees that is bounded by a circle
   having a 35 mile radius and centered at the station's reference coordinates,
   which was the previous PSA entitled to incumbent licensees prior to January
   10, 2005, and is bounded by the chord(s) drawn between intersection points
   of the licensee's previous 35 mile PSA and those of respective adjacent
   market, co-channel licensees; or:

   (2) The BTA that is licensed to the respective BRS BTA authorization holder
   subject to the exclusion of overlapping, co-channel incumbent GSAs as
   described in paragraph (a)(1) of this section.

   (b) If the license for an incumbent BRS station cancels or is forfeited, the
   GSA area of the incumbent station shall dissolve and the right to operate in
   that area automatically reverts to the GSA licensee that held the
   corresponding BTA.
