Sec. 97.203  Beacon station.

    (a) Any amateur station licensed to a holder of a Technician, 
General, Advanced or Amateur Extra Class operator license may be a 
beacon. 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 28.20-28.30 MHz, 50.06-50.08 MHz, 144.275-144.300 
MHz, 222.05-222.06 MHz or 432.300-432.400 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.
    (f) A beacon must cease transmissions upon notification by an EIC 
that the station is operating improperly or causing undue interference 
to other operations. The beacon may not resume transmitting without 
prior approval of the EIC.
    (g) A beacon may transmit one-way communications.
