FCC Regulations - Part 97 Amateur Radio Service
[Effective Oct 1, 2006.]
Subpart B Station Operation Standards
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 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
(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, Technician, or Technician Plus Class to General Class: AG;
(3) For a control operator who has requested a license modification
from Novice, Technician, Technician Plus, General, or Advanced Class to
Amateur Extra Class: AE.
(g) When the station is transmitting under the authority of Sec.
97.107 of this part, an indicator consisting of the appropriate letter-
numeral designating the station location must be included before the
call sign that was issued to the station by the country granting the
license. For an amateur service license granted by the Government of
Canada, however, the 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.
