S.I. No. 330/1937 - Wireless Telegraphy Act, 1926.

1. The station shall always be equipped for receiving as well as sending. The sending apparatus shall invariably be tuned accurately to the particular frequency within the authorised bands on which it is intended to send, and for that purpose there shall be kept at the station and used whenever necessary a reliable instrument of the piezo-electric crystal or other type approved by the Minister for accurately controlling or measuring the frequency of emissions from the station. The licensee shall furnish to the Minister a certificate in respect of each crystal showing the degree of accuracy to be not less than 0·1 per cent. The licensee shall take all practicable steps to maintain the accuracy of such measuring instrument and shall observe any detailed instructions in that connection which may be issued by the Minister.

2. The licensee shall take precautions to ensure that emissions from the station shall always be as stable as possible (i.e., as free as possible from variation, other than necessary modulations, from the frequency intended to be used), and shall also be as free as possible from harmonics and other unessential emissions.

3. The station must be operated only by the licensee or by a properly qualified operator approved of by the Minister.

4. The power, frequencies (wavelengths) and systems of wireless telegraphy employed by the licensee shall be as specified in his experimenter's licence.

5. The licensee shall not use apparatus emitting damped waves (spark) and shall not use unrectified alternating current on the anodes of transmitting valves. Neither shall the licensee use interrupted continuous wave (I.C.W.) or tonic train for transmission unless he has satisfied the Minister that such systems are essential for his experiments.

6. The licensee may carry out experiments involving sending at all times, unless interference is caused to other wireless telegraphy services in which event sending may be prohibited during such periods as the Minister may consider necessary.

7. The licensee shall not commence sending without listening-in on the frequency which is to be used in order to ascertain whether interference is likely to be caused thereby with any other wireless station which may be working. No period of sending shall exceed ten consecutive minutes' duration and each period of sending shall be followed by a period of not less than three minutes listening-in on the frequency used.

8. The licensee shall at once discontinue or postpone sending at the request of any government or commercial station.

9. A record shall be kept by the licensee of all transmissions showing the date and time of each transmission and the frequency and system (i.e., continuous wave or telephony) employed.

10. Transmissions from the station must be limited to messages relating to the experiments.

11. All messages must be in plain language, but the recognised abbreviations used in radio communication may be regarded as plain language for this purpose.

12. The licensee may send messages only to stations which are actually co-operating in the experiments. Messages may be sent to such stations in the Irish Free State and also in other countries except where the government of the country has prohibited such communications.

13. When calling up another station the licensee shall send the call signal of that station not more than three times, the word "de" once and the call signal of his own station not more than three times. In answering a call the call signal of the calling station shall be sent not more than three times, the word "de" once and the call signal of the licensee's station once. The licensee shall also send the call signal of the station at the beginning and end of each subsequent period of transmitting and on every occasion when the wavelength is changed.

14. The station shall be used in such a manner as to cause no interference with other stations ; in particular reaction must not be used for receiving to such an extent as to energise any neighbouring aerial.

The arrangement employed for "keying" the transmitter must be such that interference due to "key clicks" is not produced in neighbouring receiving apparatus.

15. The licensee shall not use or allow the station to be used for the receipt of messages other than messages intended for receipt thereby or sent for general reception. If any other message is unintentionally received by means of the station the licensee shall not make known or allow to be made known its contents, its origin or destination, or the fact of its receipt to any person (other than a duly authorised officer of the Government of Saorstát Eireann or a competent legal tribunal).

I consent to the making of the foregoing Regulations in so far as they relate to fees.

16. Every station in respect of which an experimenter's licence is in force, and the records of transmissions kept in respect of such station in pursuance of the conditions contained in the Third Schedule to these Regulations, and also the experimenter's licence for the time being in force in respect of such station shall be open to inspection at all reasonable times by any officer of the Minister authorised in that behalf in writing by the Minister.

WIRELESS TELEGRAPHY (EXPERIMENTER'S LICENCE) REGULATIONS, 1937.

WHEREAS it is enacted by sub-section (1) of

Section 6

of the

Wireless Telegraphy Act, 1926

(No. 45 of 1926), that the Minister for Posts and Telegraphs may by order make regulations prescribing certain matters mentioned in the said sub-section in relation to all licences granted under that Act or any particular class or classes of such licences, and it is enacted by sub-section (2) of the said section that regulations made under the said section may authorise and provide for the granting of a licence under the said Act subject to special terms, conditions, and restrictions to any person who satisfies the said Minister that he requires the licence solely for the purpose of conducting experiments in wireless telegraphy

AND WHEREAS it is enacted by sub-section (3) of the said section that no regulation shall be made under the said section in relation to fees without the previous consent of the Minister for Finance.

NOW, I, OSCAR TRAYNOR, Minister for Posts and Telegraphs, in exercise of the powers conferred on me by
