A holder of a Technician, General, Advanced or Amateur Extra Class operator license may be the control operator of a beacon, subject to the privileges of the class of operator license held.
(b) A beacon must not concurrently transmit on more than 1 channel in the same amateur service frequency band, from the same station location.
(c) The transmitter power of a beacon must not exceed 100 W.
(d) A beacon may be automatically controlled while it is transmitting on the 28.20â€“28.30 MHz, 50.06â€“50.08 MHz, 144.275â€“144.300 MHz, 222.05â€“222.06 MHz or 432.300â€“432.400 MHz segments, or on the 33 cm and shorter wavelength bands.
(e) Before establishing an automatically controlled beacon in the National Radio Quiet Zone or before changing the transmitting frequency, transmitter power, antenna height or directivity, the station licensee must give written notification thereof to the Interference Office, National Radio Astronomy Observatory, P.O. Box 2, Green Bank, WV 24944.
(1) The notification must include the geographical coordinates of the antenna, antenna ground elevation above mean sea level (AMSL), antenna center of radiation above ground level (AGL), antenna directivity, proposed frequency, type of emission, and transmitter power.
(2) If an objection to the proposed operation is received by the FCC from the National Radio Astronomy Observatory at Green Bank, Pocahontas County, WV, for itself or on behalf of the Naval Research Laboratory at Sugar Grove, Pendleton County, WV, within 20 days from the date of notification, the FCC will consider all aspects of the problem and take whatever action is deemed appropriate.
