97.7 states that EVERY amateur station (remember, a repeater is an amateur station: see 97.3(a)(39)) must have a control operator: §97.7 Control operator required. When transmitting, each amateur station must have a control operator. The control operator must be a person: (a) For whom an amateur operator/primary station license grant appears on the ULS consolidated licensee database, or (b) Who is authorized for alien reciprocal operation by §97.107 of this part And Station control is defined in 97.109: §97.109 Station control. (a) Each amateur station must have at least one control point. (b) When a station is being locally controlled, the control operator must be at the control point. Any station may be locally controlled. (c) When a station is being remotely controlled, the control operator must be at the control point. Any station may be remotely controlled. (d) When a station is being automatically controlled, the control operator need not be at the control point. Only stations specifically designated elsewhere in this Part may be automatically controlled. Automatic control must cease upon notification by a District Director that the station is transmitting improperly or causing harmful interference to other stations. Automatic control must not be resumed without prior approval of the District Director. (e) No station may be automatically controlled while transmitting third party communications, except a station transmitting a RTTY or data emission. All messages that are retransmitted must originate at a station that is being locally or remotely controlled. And 97.205(d) states that a repeater may be automatically controlled. So, taking them all together, a repeater MUST have a control operator, MAY be under automatic control, and at all times when NOT operating under automatic control, MUST be either locally (someone physically at the control point) or remotely (RF or wireline) controlled. If remotely controlled over RF, the control link is in auxiliary operation, and may only be carried out in the frequency segments specifically authorized in 97.201, which, as someone else already pointed out, were recently expanded to include certain sub-bands on 2 meters.
