Sec. 23.37 Station identification.
(a) General. Every radiotelegraph or radiotelephone station in the
International Fixed Public or Fixed Public Press Service shall transmit, as
provided below, the identifying call sign or other approved identification
signal on each of its assigned frequencies below 30 MHz on which energy is
being radiated.
(b) When required. (1) The call sign assigned to each frequency shall be
transmitted on that frequency at the beginning and end of each period of use
of the frequency.
(2) During regular operation on any freuency, the call sign or other
approved identification signal shall be transmitted at least at hourly
intervals within the period from 10 minutes before to 10 minutes after each
hour. If identification during this period would require an interruption in
the transmission of a radio-photo, a telephone conversation, an addressed
program or a multiple addressed press message, or a break in the continuity
of a “conference” or “leased line” type of service, the identifying signal
shall be transmitted at the first break in, at the conclusion of, or
simultaneously with, the particular transmission as described below.
(c) Methods of transmission. (1) All identifying signals shall be
transmitted in such a manner as to permit identification without special
equipment other than communication type receivers, except as provided in
paragraph (e) of this section. When emissions are being used which are not
capable of identification without special equipment, the identifying signal
shall be transmitted by one of the following methods:
(i) By interrupting the transmission and transmitting the call sign in a
manner which can be identified without special equipment.
(ii) By superimposing the call sign or other approved identification signal
on the emission being transmitted without interrupting the transmission as
provided for by paragraphs (e) and (f) of this section.
(d) Emissions to be used. (1) Except as otherwise provided, the following
emissions shall be used for identification:
(i) Radiotelegraph stations. The identifying call sign shall be transmitted
by International Morse code at a speed not to exceed 25 words per minute and
shall consist of the signal “QRA de” followed by the call sign. This
transmission shall be made at least three times.
(ii) Radiotelegraph stations using telephone type emissions. When telephone
type emissions are being used in accordance with Sec. 23.11, identification may
be made by voice and shall consist of announcing three times in English the
call sign of the frequency being used
(iii) Radiotelephone stations. The identifying transmission may be made
utilizing either telegraph or telephone type emissions. When telegraph
emission is used, the transmission shall be made in International Morse Code
at a speed not to exceed 25 words per minute and shall consist of the signal
“QRA de” followed by the call sign. This transmission shall be made at least
three times. When telephone emission is used, the identification shall
consist of announcing three times in English the call sign of the frequency
being used, provided that all privacy or secrecy devices shall be removed
from the circuit during such transmissions.
(e) Superimposed identification. Radiotelegraph or radiotelephone stations
identifying simultaneously with transmission of traffic: call signs or the
general identification signal described in paragraph (f) of this section may
be superimposed on the emission being transmitted by any method which will
make identification possible with communication type receivers provided that
approval of any such method shall first have been obtained from the Federal
Communications Commission. (Approval by the Federal Communications
Commission of any means of identification of complex emissions by
superimposing identification of regular transmissions will be given upon
satisfactory completion of coordinated tests thereof by the applicant and
the Commission's Field Engineering Bureau.) Commission approval may be
withdrawn if at any subsequent time harmful interference to adjacent
frequencies is caused by the superimposed identification. When superimposed
identification by call sign is used, the identifying signal shall consist of
“QTT de (call sign)” transmitted at least three times in International Morse
Code at a speed not to exceed 25 words per minute.
(f) General identification signal. When an approved method of superimposed
identification is used, the identification signal shall consist of “QTT de
(abbreviated name of company recorded with the Commission) (abbreviated name
of station recorded with the Commission).” (It is suggested that
“abbreviated company name” consist of two to five letters such as the
initials of the company name and that “abbreviated name of station” consist
of two or three letters indicating the name of the city where the licensee's
message center is located. Both of these abbreviations shall be notified to
the Commission before being used for identification.) This general
identification signal shall be transmitted in International Morse Code at a
speed not to exceed 25 words per minute and may be transmitted continuously
or intermittently as desired provided that it shall be transmitted for at
least five minutes total time during the period from 10 minutes before to 10
minutes after each hour that energy is being radiated on the frequency. The
same signal may be superimposed on all transmissions being made at a
particular station: Provided, however, That licensed call signs shall be
transmitted on the frequencies to which they are assigned as often as is
practicable and reasonable or at least at the beginning and end of each
period of use of each frequency.
(g) Identification by printer. Notwithstanding the other provisions of this
section with respect to methods of transmission, when single channel
start-stop 5 unit code printer equipment is being used, the identifying call
sign may be transmitted by means of printer signals. When identification is
made by printer signals, it shall consist of the call sign for the
particular frequency being used and shall be made at least three times at a
speed of approximately 60 words per minute.
