No. 318/1939:

MERCHANT SHIPPING (WIRELESS TELEGRAPHY) RULES, 1939.

MERCHANT SHIPPING (WIRELESS TELEGRAPHY) RULES, 1939.

The Minister for Industry and Commerce, in consultation with the Minister for Posts and Telegraphs, in pursuance of the powers conferred on him by the Merchant Shipping (Wireless Telegraphy) Act, 1919 (as adapted by subsequent enactments), and the Merchant Shipping (Safety and Load Line Conventions) Act, 1933 (No. 42 of 1933), hereby makes the following rules:—

PART I. PRELIMINARY AND GENERAL.

1. These Rules may be cited as the Merchant Shipping (Wireless Telegraphy) Rules, 1939.

2. The Interpretation Act, 1937 (No. 38 of 1937), applies to these Rules.

3. (1) These Rules apply to every ship to which the Merchant Shipping (Wireless Telegraphy) Act, 1919, applies.

(2) In these Rules the word "ship" means a ship to which these Rules apply.

4. For the purposes of these Rules, ships shall be classified in the following manner, that is to say :—

(a) passenger steamers of 3,000 tons gross tonnage or upwards and ships, not being passenger steamers, of over 5,500 tons gross tonnage (in these Rules referred to as ships belonging to class I),

(b) passenger steamers of under 3,000 tons gross tonnage and ships, not being passenger steamers, of not more than 5,500 and not less than 3,000 tons gross tonnage (in these Rules referred to as ships belonging to class II),

(c) ships, not being passenger steamers, of less than 3,000 and not less than 1,600 tons gross tonnage (in these Rules referred to as ships belonging to class III).

5. Nothing in these Rules shall be deemed to relieve the owner of a ship from compliance with the provisions of any other rules for the time being in force in relation to wireless telegraphy on ships.

6. The Merchant Shipping (Wireless Telegraphy) Rules, 1920, and the Merchant Shipping (Wireless Telegraphy) Rules Amendment Rules, 1926 (Statutory Rules and Orders, No. 28 of 1926), are hereby revoked.

PART II. THE WIRELESS TELEGRAPH INSTALLATION.

7. (1) In this Part of these Rules, the expression "normal range" used in relation to a transmitter means the distance in nautical miles that signals on a frequency of 500 kilocycles (wavelength : 600 metres) can be transmitted by means of such transmitter over sea in day-time under normal conditions and circumstances so as to be clearly perceptible by means of a receiver employing a rectifier of the crystal type without amplification devices.

(2) In this Part of these Rules—

(a) references to the reckoning of the normal range of a transmitter shall be construed as meaning the reckoning of such normal range in relation to the power of such transmitter in metre amperes in the case of type B, or fully modulated type A2 transmitters, on the assumption that 100, 80 and 50 nautical miles correspond respectively to 60, 45 and 25 metre amperes and that the number of metre amperes is determined by multiplying the actual height in metres of the aerial, at its highest point above the deepest load water line of the ship in which such transmitter is provided, by the current in amperes measured at the base of the aerial, and

(b) references to the proving by test of the normal range of a transmitter shall be construed as meaning the proving of such normal range by test with a wireless telegraphy station designated by the Minister for Posts and Telegraphs as a standard station for marine wireless telegraphy range tests.

8. Every ship shall be provided with efficient wireless transmitting and receiving apparatus (in these Rules referred to as the apparatus) of a type approved by the Minister for Posts and Telegraphs.

9. The apparatus shall comply with the following conditions, that is to say :—

(a) it shall be capable of transmitting—

(c) it shall be capable of receiving by means of a rectifier of the crystal type,

(d) it shall be capable of permitting changes of frequency and, when communication is established, changes from transmission to reception and from reception to transmission to be made as rapidly as possible,

(e) the transmitter shall have a note frequency of at least 100,

(f) the normal range of the transmitter shall be such as complies with the following requirements, that is to say :

(i) when such normal range is reckoned, it shall be not less than 100 nautical miles, and

(ii) when such normal range is proved by test, it shall be not less than 150 nautical miles,

(g) it shall be provided with an independent source of electrical energy sufficient to maintain continuous full operation for a period of at least six hours without recourse to the propelling power of the ship or the main electricity system of the ship,

(h) all dangerous parts shall be screened or effectively isolated, and

(i) it shall not, on or after the 1st day of January, 1940, use waves of type B unless the full power measured at the terminals of the alternator is less than 300 watts.

(II) when such normal range is proved by test, it shall be not less than 120 nautical miles,

(iv) in the case of a ship belonging to class II or class III, the normal range of the transmitter shall be such as complies with the following requirements, that is to say :

(I) when such normal range is reckoned, it shall be not less than 50 nautical miles, and
