(a) (1) The frequency 500 kc/s is the general international calling frequency, which shall be used by any coast station engaged in radiotelegraphy in the authorized band 405-535 kc/s.

(2) The frequency for replying to a call sent on the general calling frequency is 500 kc/s, except where the calling station requests that the reply be made on an authorized working frequency. In Region 2, and in other areas of heavy traffic, ship stations should request coast stations to answer on their normal working frequency.

(3) In order to facilitate the reception of distress calls, all transmissions on the frequency 500 kc/s shall be reduced to a minimum.

(4) When the frequency 500 kc/s is being used for distress, the coast station shall normally reply on its working frequency to a ship station call made on the supplementary calling frequency 512

kc/s,1 however, when requested to do so by the calling ship station, the coast station may reply on 512 kc/s. Under these circumstances, coast stations may also use 512 kc/s as a calling frequency, however, transmissions on 512 kc/s shall be limited to the minimum necessary to establish communications and to shift to its working frequency.

(b) The frequency 143 kc/s (class Al emission only) is the international calling frequency used by stations of the maritime mobile service in the band 90160 kc/s. When a ship station which uses frequencies in the band 90-160 kc/s desires to establish communication with a coast station, it shall call on the frequency 143 kc/s unless the International List of Coast Stations provides otherwise. Coast stations shall reply on their normal working frequency in this band. The frequency 143 kc/s shall be used exclusively for individual calls, replies to such calls, and the transmission of signals preparatory to traffic.

(c) All radio-channels within the band 4000 kc/s to 23000 kc/s similarly authorized for working may be used for calling also: Provided, Interference is not caused to any communication in progress on the particular working channel.

(d) The normal calling frequency to be used by each coast station employing telegraphy when operating in the band 2035-2065 kc/s is its normal working frequency in this band. In addition to the transmission on the authorized working frequency in this band, coast stations may transmit on any frequency within the ship station calling band 2088.5 to 2093.5 kc/s for transmission of distress traffic exclusively.

§ 81.208 Frequencies for working.

(a) Each assigned frequency listed in § 81.206(a), and which is not identified therein with a specific use or function is authorized as an assigned frequency for "working".

(b) The calling channel of which 500 kc/s is the assigned frequency may be used for the transmission of distress, urgency, and safety messages; any other use of this channel for working is prohibited.

(c) Coast stations having frequency assignments within the band 5000 kc/s to

1 Available for assignment to ship and coast stations on Apr. 1, 1969.

25000 kc/s shall conduct their operations so as to reserve, in so far as is practicable, the use of frequencies within this band for communication over the relatively long distances for which these frequencies are particularly effective.

(d) In addition to the frequency assignment designated for telegraphy in the license of a ship station, such station, when working by means of telegraphy with a coast station, may, on condition that its emission-bandwidth and frequency tolerance shall be within the respective limits thereof permitted for the coast station, transmit:

(1) On a telegraph working channel of a coast station within the band 110 to 150 kc/s when directed to do so by the coast station for which the channel is authorized: Provided, Interference is not caused to the service of any land, fixed, broadcast, or radiolocation station: And provided, That the emission shall be class Al only.

(2) On a telegraph working channel of a coast station within the band 415 to 490 kc/s when directed to do so by the coast station for which the channel is authorized.

(3) Coast stations are authorized to direct ship stations to operate in accordance with the provisions of this section, whenever such means of operation is possible and appropriate.

§ 81.209 Use of Morse Code required.

The signal code employed for telegraphy by stations in the maritime mobile service shall be the Morse Code signals specified in the Telegraph Regulations annexed to the International Telecommunication Convention, Geneva, 1959. However, for radiotelegraph communication of a special character, the use of other signals may be specifically authorized by the Commission in response to an appropriate application therefor.

[blocks in formation]

They shall be transmitted always upon completion of any transmission when the station resumes its watch or suspends transmission for an indefinite time; in addition they shall be transmitted at intervals not exceeding 20 minutes whenever transmission is sustained for a period exceeding 20 minutes. § 81.211 Procedure in testing.

(a) Coast stations must use every precaution to insure that, when conducting operational transmitter tests, the emissions of the station will not cause harmful interference. Radiation must be reduced to the lowest practicable value and if feasible shall be entirely suppressed. When radiation is necessary or unavoidable, the radiotelegraph testing procedure described below shall be followed.

(1) The licensed radiotelegraph operator responsible for operation of the transmitting apparatus shall ascertain by careful listening that the test emissions will not be likely to interfere with transmissions in progress.

(2) The operator shall transmit the signal "IE" (two dots, space, one dot) on the test frequency as a warning that test emissions are about to be made on that frequency. When the frequency or frequencies of the test emissions is/are within the frequency-band 405 to 535 kc/s, a listening watch shall be maintained on 500 kc/s by a licensed radiotelegraph operator at the station throughout the test period.

(3) If, as a result of transmitting the test signal "IE", any station indicates, by transmitting the signal "AS" (wait), that it anticipates harmful interference, testing shall be suspended. When transmission of "IE" is resumed and no response is observed, and careful listening indicates that harmful interference should not be caused, the operator shall proceed as set forth in subparagraph (4) of this paragraph.

(4) Test signals composed of a series of "VVV" followed by the call sign of the testing station shall be transmitted. The call sign shall be sent clearly and at relatively slow speed.

(b) When testing is conducted on the frequency 500 kc/s, the test signals shall not continue for more than 10 seconds, and no tests shall be conducted during the 500 kc/s silence periods. Care must be exercised not to so prolong and space the dash portion of the "VVV" series as to form the alarm signal.

§ 81.212 Radiotelegraph operating procedure.

(a) Except for the transmission of distress or urgency signals, all transmissions by coast stations must cease within the band 485 to 515 kc/s during each 500 kc/s silence period, i.e., for three minutes twice an hour beginning at x h. 15 and x h. 45, Greenwich mean time (G. M. T.).

(b) In order to facilitate radiotelegraph communication in the maritime mobile service, all coast stations transmitting by means of telegraphy shall, whenever practicable, use the service abbreviations (“Q” signals) listed in Appendix 13 to the International Radio Regulations, Geneva, 1959.

(c) In addition to compliance with all applicable sections of this part, the operation of coast stations using telegraphy for call, reply, and the transmission of message traffic shall, in particular, comply with all applicable provisions of Articles 29, 30, 31, 37, 38, and 39 of the International Radio Regulations, Geneva, 1959.
