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.

              Symbol                               Usage

D................................  Daily regular use during business
                                    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.

   (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.
