Sec. 97.119  Station identification.

    (a) Each amateur station, except a space station or telecommand 
station, must transmit its assigned call sign on its transmitting 
channel at the end of each communication, and at least every 10 minutes 
during a communication, for the purpose of clearly making the source of 
the transmissions from the station known to those receiving the 
transmissions. No station may transmit unidentified communications or 
signals, or transmit as the station call sign, any call sign not 
authorized to the station.
    (b) The call sign must be transmitted with an emission authorized 
for the

[[Page 688]]

transmitting channel in one of the following ways:
    (1) By a CW emission. When keyed by an automatic device used only 
for identification, the speed must not exceed 20 words per minute;
    (2) By a phone emission in the English language. Use of a phonetic 
alphabet as an aid for correct station identification is encouraged;
    (3) By a RTTY emission using a specified digital code when all or 
part of the communications are transmitted by a RTTY or data emission;
    (4) By an image emission conforming to the applicable transmission 
standards, either color or monochrome, of Sec. 73.682(a) of the FCC 
Rules when all or part of the communications are transmitted in the same 
image emission; or
    (5) By a CW or phone emission during SS emission transmission on a 
narrow bandwidth frequency segment. Alternatively, by the changing of 
one or more parameters of the emission so that a conventional CW or 
phone emission receiver can be used to determine the station call sign.
    (c) One or more indicators may be included with the call sign. Each 
indicator must be separated from the call sign by the slant mark (/) or 
by any suitable word that denotes the slant mark. If an indicator is 
self-assigned, it must be included before, after, or both before and 
after, the call sign. No self-assigned indicator may conflict with any 
other indicator specified by the FCC Rules or with any prefix assigned 
to another country.
    (d) When transmitting in conjunction with an event of special 
significance, a station may substitute for its assigned call sign a 
special event call sign as shown for that station for that period of 
time on the common data base coordinated, maintained and disseminated by 
the special event call sign data base coordinators. Additionally, the 
station must transmit its assigned call sign at least once per hour 
during such transmissions.
    (e) When the operator license class held by the control operator 
exceeds that of the station licensee, an indicator consisting of the 
call sign assigned to the control operator's station must be included 
after the call sign.
    (f) When the control operator is a person who is exercising the 
rights and privileges authorized by Sec. 97.9(b) of this part, an 
indicator must be included after the call sign as follows:
    (1) For a control operator who has requested a license modification 
from Novice Class to Technical Class: KT;
    (2) For a control operator who has requested a license modification 
from Novice or Technical Class to General Class: AG;
    (3) For a control operator who has requested a license modification 
from Novice, Technician, or General Class operator to Advanced Class: 
AA; or
    (4) For a control operator who has requested a license modification 
from Novice, Technician, General, or Advanced Class operator to Amateur 
Extra Class: AE.
    (g) When the station is transmitting under the authority of a 
reciprocal permit for alien amateur licensee, an indicator consisting of 
the appropriate letter-numeral designating the station location must be 
included before the call sign issued to the station by the licensing 
country. When the station is transmitting under the authority of an 
amateur service license issued by the Government of Canada, a station 
location indicator must be included after the call sign. At least once 
during each intercommunication, the identification announcement must 
include the geographical location as nearly as possible by city and 
state, commonwealth or possession.
