Section 73.1125 of the Rules (47 C.F.R. § 73.1125) requires the licensee of a broadcast station to maintain a main studio at one of the following locations: (1) within the station's community of license; (2) at any location within the principal community contour of any AM, FM, or TV broadcast station licensed to the station's community of license; or (3) within twenty-five miles from the reference coordinates of the center of its community of license.

In adopting the main studio rules, the Commission stated that the station's main studio must have the capability to serve the needs and interests of the residents of the station's community of license. See Main Studio and Program Origination Rules, 2 FCC Rcd 3215, 3217-18(1987), clarified, 3 FCC Rcd 5024, 5026(1988). To fulfill this function, a station must, among other things, maintain a meaningful presence at its main studio. The Commission has defined a minimally acceptable “meaningful presence” as full-time managerial and full-time staff personnel. See Jones Eastern of the Outer Banks, Inc., 6 FCC Rcd 3615, 3616(1991), clarified 7 FCC Rcd 6800(1992).

The licensee need not have the same staff person and manager at the studio, as long as there is management and staff presence there during normal business hours. See Jones Eastern of the Outer Banks, Inc., 6 FCC Rcd at 3616 n.2; 7 FCC Rcd 6800 n.4. Normal business hours means any eight hour period between eight o'clock am and six o'clock pm, local time.
