license station grant on the ULS consolidated licensee database to be 

the control operator of an amateur station.

    (2) Amateur radio services. The amateur service, the amateur-

satellite service and the radio amateur civil emergency service.

    (4) Amateur service. A radiocommunication service for the purpose of 

self-training, intercommunication and technical investigations carried 

out by amateurs, that is, duly authorized persons interested in radio 

technique solely with a personal aim and without pecuniary interest.

    (5) Amateur station. A station in an amateur radio service 

consisting of the apparatus necessary for carrying on 

radiocommunications.

of a station when it is transmitting so that compliance with the FCC 

Rules is achieved without the control operator being present at a 

control point.

    (7) Auxiliary station. An amateur station, other than in a message 

forwarding system, that is transmitting communications point-to-point 

within a system of cooperating amateur stations.

    (8) Bandwidth. The width of a frequency band outside of which the 

mean power of the transmitted signal is attenuated at least 26 dB below 

the mean power of the transmitted signal within the band.

    (11) Call sign system. The method used to select a call sign for 

amateur station over-the-air identification purposes. The call sign 

systems are:

    (i) Sequential call sign system. The call sign is selected by the 

FCC from an alphabetized list corresponding to the geographic region of 

the licensee's mailing address and operator class. The call sign is 

shown on the license. The FCC will issue public announcements detailing 

the procedures of the sequential call sign system.

    (ii) Vanity call sign system. The call sign is selected by the FCC 

from a list of call signs requested by the licensee. The call sign is

    (iii) Special event call sign system. The call sign is selected by 

the station licensee from a list of call signs shown on a common data 

base coordinated, maintained and disseminated by the amateur station 

special event call sign data base coordinators. The call sign must have 

the single letter prefix K, N or W, followed by a single numeral 0 

through 9, followed by a single letter A through W or Y or Z (for 

example K1A). The special event call sign is substituted for the call

functioning of a radionavigation service or of other safety services or 

seriously degrades, obstructs or repeatedly interrupts a 

radiocommunication service operating in accordance with the Radio
