Sec. 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, General, Advanced or Amateur Extra 
Class operator license

[[Page 690]]

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, 50.0-51.0 
MHz, 144.0-144.5 MHz, 145.5-146.0 MHz, 222.00-222.15 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 non-
coordinated 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, tramsitter power, antenna 
height or directivity, or the location of 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.
    (g) The control operator of a repeater that retransmits 
inadvertently communications that violate the rules in this part is not 
accountable for the violative communications.
