§  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.
