Sec.  97.203   Beacon station.

   (a) Any amateur station licensed to a holder of a Technician, Technician
   Plus, General, Advanced or Amateur Extra Class operator license may be a
   beacon. A holder of a Technician, Technician Plus, 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 a District
   Director  that  the  station  is operating improperly or causing undue
   interference to other operations. The beacon may not resume transmitting
   without prior approval of the District Director.

   (g) A beacon may transmit one-way communications.
