What must the control operator of a repeater operating in the 70-centimeter band do if a radiolocation system experiences interference from that repeater?
Reduce the repeater antenna HAAT (Height Above Average Terrain)
File an FAA NOTAM (Notice to Air Missions) with the repeater system's ERP, call sign, and six-character grid locator
Cease operation or make changes to the repeater that mitigate the interference✓پاسخ درست
All these choices are correct
توضیح
Amateur use of the 70-centimeter band is secondary to government radiolocation, so a repeater that causes harmful interference to a radiolocation system must cease or be changed until the interference stops. Lowering the antenna is only one possible mitigation rather than the required remedy, and no FAA notice applies to this situation.
