Sec. 23.41  Quarterly report of frequency usage.

    (a) Transmitted frequencies. Each licensee in the international 
fixed radio-communication services shall submit a report of frequency 
usage for all authorized frequencies below 30 MHz for each station. If 
more than one station is operated from a common control point, reports 
for the stations may be combined into one. This report shall be due 40 
days after the close of each calendar quarter and shall contain the 
following information: Each frequency assigned to the station or 
stations and the number of hours it was used during the quarter to each 
point of communication for each class of service rendered (such as 
telegraph, telephone, program, or radiophoto), the types of emission 
normally used to each point of communication, and the total hours each 
frequency was used.
    (b) Received frequency report. Upon specific request by the 
Commission, licensees in the international fixed public 
radiocommunication services shall furnish promptly the following 
information regarding frequencies received from all points of 
communication: All frequencies received, including call signs, location 
of transmitting station, type and bandwidth of emission normally 
employed, point of reception, and a symbol from the following table 
indicating the amount of usage of the particular received frequency.

                                    days.                               
O................................  Occasional use; not used daily, but  
                                    offered frequently when required by 
                                    propagation or operational          
                                    conditions.                         
S................................  Seldom received; where records       
                                    indicate light use during the past  
                                    year.                               
L................................  Limited use; limited by solar        
                                    activity to a part of the solar     
                                    cycle or to a part of each year.    
------------------------------------------------------------------------


The following criteria shall be used to determine whether or not a 
frequency shall be reported as received:
    (1) Report all frequencies regularly used during the period under 
consideration.

[[Page 228]]

    (2) Report frequencies received consistently during a substantial 
part of any cyclical change in frequency usefulness even though they may 
be unused for considerable periods of time during another part of the 
cycle.
    (3) Do not report any frequency, the use of which is known to have 
been discontinued or transferred to another operation by a foreign 
correspondent.
    (4) Do not report any frequency which has been inactive for a period 
of 6 months or longer, except as indicated in paragraph (b)(2) of this 
section.
