Subpart C -- Special Operations

     S 97.201 Auxiliary station.
     (a) Any amateur station licensed to a holder of a 
Technician, General, Advanced or Amateur Extra Class operator 
license may be an auxiliary station. A holder of a Technician, 
General, Advanced or Amateur Extra Class operator license may be 
the control operator of an auxiliary station, subject to the 
privileges of the class of operator license held.
     (b) An auxiliary station may transmit only on the 1.25 m and 
shorter wavelength bands, except the 220.0-220.5 MHz, 431-433 MHz 
and 435-438 MHz segments.
     (c) Where an auxiliary station causes harmful interference 
to another auxiliary station, the licensees are equally and fully 
responsible for resolving the interference unless one station's 
operation is recommended by a frequency coordinator and the other 
station's is not. In that case, the licensee of the non-
coordinated auxiliary station has primary responsibility to 
resolve the interference.
     (d) An auxiliary station may be automatically controlled 
only when it is part of a system that includes a repeater station 
also being automatically controlled.
     (e) An auxiliary station may transmit one-way 
communications.
     S 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, 144.05-
144.06 MHz, 220.05-220.06 MHz, 222.05-222.06 MHz or 432.07-432.08 
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 Country, 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.
     S 97.205 Repeater station.
     (a) Any amateur station licensed to a holder of a 
Technician, General, Advanced or Amateur Extra Class operator 
license may be a repeater. A holder of a Technician, Genera, 
Advanced or Amateur Extra Class operator license may be the 
control operator of a repeater, subject to the privileges of the 
class of operator license held.
     (b) A repeater may receive and retransmit only on the 10 m 
and shorter wavelength frequency bands except the 28.0-29.5 MHz, 
50.0-52.0 MHz, 144.0-144.5 MHz, 145.5-146.0 MHz 220.0-220.5 MHz, 
431.0-433.0 MHz and 435.0-438.0 MHz segments.
     (c) Where the transmissions of a repeater cause harmful 
interference to another repeater, the two station licensees are 
equally and fully responsible for resolving the interference 
unless the operation of one station is recommended by a frequency 
coordinator and the operation of the other station is not. In 
that case, the licensee of the noncoordinated repeater has 
primary responsibility to resolve the interference.
     (d) A repeater may be automatically controlled.
     (e) Ancillary functions of a repeater that are available to 
users on the input channel are not considered remotely controlled 
functions of the station. Limiting the use of a repeater to only 
certain user stations is permissible.
     (f) Before establishing a repeater in the National Radio 
Quiet Zone or before changing the transmitting frequency, 
transmitter power, antenna height or directivity, or the location 
an existing repeater, 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 station 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.
