G. MINUTES OF THE SECOND PLENARY (CLOSING) MEETING OF THE C. C. I. RADIO, THE HAGUE, OCTOBER 2, 1929 The meeting was called to order by M. BOETJE, President, at 3:45 p. m. The PRESIDENT stated that the minutes of the first plenary meeting had been distributed on September 10. To save time, and according to custom, he proposed that these should be approved, subject to any changes that might be notified to the secretariat. This was agreed on. The following communication was read: MR. PRESIDENT, THE HAGUE, October 2, 1929. The Delegation of the U. S. S. R. has the honor to inform the first session of the C. C. I. Radio of the following: The U. S. S. R., not having adhered to the Washington acts and not being bound by their provisions, the Postal Administration of the U. S. S. R. considers the opinions expressed by the first session of the C. C. I. Radio as the valuable results of the work done by an international scientific and technical body composed of eminent scientists and technicians of various countries. This work is a great step forward towards an understanding in the international radio domain. With regard to the references to the Washington treaties to be found in the discussions and opinions of the first meeting of the C. C. I. Radio, they are regarded by the U. S. S. R. Delegation as being purely informatory. I have the honor to be, etc. MONSIEUR BOETJE, DR. E. HIRSCHFELD Chief of the U. S. S. R. Delegation President of the First Session of the C. C. I. Radio, THE HAGUE The PRESIDENT pointed out that this letter was communicated to the Assembly for information. In accordance with Article 9 of the Rules of Procedure of the First Meeting of the C. C. I Radio, the Assembly began to consider the draft recommendations prepared by the different committees. These opinions, the text of which is reproduced hereafter, were unanimously approved. TOPIC 1 OF THE PROGRAM STUDY OF QUESTIONS ON THE PROGRAM OF MEETINGS OF THE C. C. I. RADIO The Committee on Organization, considering 1. That it is neither necessary nor possible, under the General Regulations, to set up permanent bodies for the study of questions on the program of meetings of the C. C. I. Radio; 118275-3033 505 2. That there may be questions still unsettled after meetings of the C. C. I. Radio; Unanimously expresses the opinion— 1. That, at the end of the meeting of the C. C. I. Radio, the President should read a list of important questions to be solved, and— 2. That he should ask which administrations are desirous of undertaking the preparation of proposals relating to the said questions, and ready to collaborate with the interested administrations and with private enterprises, with a view to forwarding these proposals to the administration organizing the next meeting of the C. C. I. Radio. Second Opinion LIAISON BETWEEN THE C. C. I. RADIO AND THE INTERNATIONAL BUREAU OF THE TELEGRAPH UNION The Committee on Organization, after a discussion on the question of the future organization of the C. C. I. Radio, in which the representatives of the following countries took part: Belgium, Spain, United States of America, France, Great Britain, Italy, Netherlands, Portugal, Switzerland, Czechoslovakia and the Union of Socialist Soviet Republics; after the declarations of the Director of the International Bureau of the Telegraph Union concerning the steps which he proposes to take to secure the assistance of technical experts without any increase in the sums allotted to the Bureau by the administrations; and after the declaration of the United States of America with regard to the articles of the Washington Convention and General Regulations referring to the relations of the International Bureau with the C. C. I. Radio; Unanimously expresses the opinion 1. That it is neither necessary nor possible, in accordance with present provisions, now to set up a permanent Secretariat for the C. C. I. Radio; 2. That it is sufficient to establish a close liaison between the C. C. I. Radio and the International Bureau of the Telegraph Union, it being understood that the rôle of the Bureau shall be to follow the various works of the C. C. I. Radio, with a view to the centralization and the publication of general documents for the use of administrations. Third Opinion ORGANIZATION REGULATIONS OF THE C. C. I. RADIO The Committee on Organization proposes that the following organization regulations should be adopted: Article 1 After the end of a meeting of the Committee, the administration which organized the said meeting shall conclude current business, in collaboration with the International Bureau of the Telegraph Union. It shall, as soon as possible, forward the documents to the administration organizing the next session. Article 2 Before the end of each meeting, the Committee shall name the administration that is to call the next meeting; it shall indicate any new questions and also those which have not yet been settled; the sum total of these questions shall be placed on the program for the next meeting. Article 3 After the end of a meeting all new questions, not provided by the Assembly, for submission to the Committee, shall be addressed to the administration entrusted with the task of organizing the next meeting. This administration shall enter these questions on the program for the next session. Article 4 At the last plenary session of a meeting of the Committee, the President shall announce the list of important questions to be settled. He shall then ask which administrations are desirous of undertaking the preparation of proposals relating to the said questions, and are ready to collaborate with the interested administrations and with private enterprises, with a view to the transmission of these proposals to the administration organizing the next meeting. Article 5 The administration in charge of the organization of the Committee may correspond directly with the administrations, companies and organizations capable of collaborating in the work of the Committee. It shall forward at least one copy of documents to the International Bureau of the Telegraph Union. Article 6 During the first meeting, the plenary session shall designate its President and, on the proposal of the latter, the Vice Presidents and other members of the Bureau. . Article 7 The Director of the International Bureau of the Telegraph Union or his representative shall be present at meetings and take part in the discussions in an advisory capacity. Article 8 The International Bureau of the Telegraph Union shall take part in the various activities of the Committee with a view to the centralization and the publication of general documents for the use of the administrations. Article 9 The Secretariat of the meeting shall be carried on by the organizing administration, with the collaboration of the International Bureau. Article 10 Plenary sessions shall undertake, as far as possible, to approve or reject the reports submitted by the Committees, or to order them, if necessary, to be returned to the Committees sitting during the meeting of the C. C. I. Radio; in the case of the final plenary session questions not settled shall be entered on the list referred to in Article 4. TOPIC 2 OF THE PROGRAM Opinion DEFINITION OF THE POWER OF A TRANSMITTER The Committee on Definitions and Standardization, consideringThat it is not at present practical to measure the power of a radiotransmitter, i. e., the power radiated by the antenna; That, on the contrary, the art possesses easy means of allowing the power absorbed or transformed by the various organs of a radiotransmitter to be determined, that in the case of modulated emissions, e. g., radiotelephony, the definition of the power of a transmitter is to be established so as to give, by one single number, information concerning the different types of modulation: Expresses the opinion— That the power of a radio transmitter means the power in the antenna. By antenna is meant the conductor or the whole of the radiating conductors. The power in the antenna may be obtained either by direct measurement in the antenna itself or by measurements carried out on an equivalent imaginary antenna or on other parts of the transmitter (e. g., at the input of the transmitter of a mobile station, if wished); in the case of indirect measurement, the power in the antenna will be calculated in taking account of the output of the intermediary stages. In the case of a radiotelegraph transmitter, by the power in the antenna is meant the power measured in a continuous dash. In the case of a modulated-wave transmitter, by power in the antenna is meant the product of the total resistance of the antenna multiplied by the square of the effective value of the antenna current, the rate of modulation having the greatest value compatible with the recommendations of the C. C. I. Telephone (Berlin, 1929), i. e., being such that the level of the modulation harmonics is at least 2.3 nepers or 20 decibels less than that of the fundamental wave, for the maximum power and for any frequency within the frequency-band to be transmitted. TOPIC 3 OF THE PROGRAM Opinion CLASSIFICATION OF WAVES The Committee on Definitions and Standardization, considering— That, in a classification, it is desirable to take account of the physical properties of waves, as well as of the administrative divisions to be found in the Washington Regulations; That it is also desirable to adopt limits that may be expressed, in frequency and in wave-length, by very simple figures; That the fixing of a limit at 1,500 kc/s (200 m) corresponds to a change in the mode of wave propagation noteworthy for the appearance of so-called space propagation phenomena; That the fixing of a limit at 6,000 kc/s (50 m) approximately separates waves of which the range is at all times limited from those which can practically be received all over the world's surface; That the fixing of a limit at 30,000 kc/s (10 m) approximately separates waves, the propagation of which is of the spatial type, from those where it is of the optical type; That the fixing of a limit at 100 kc/s (3,000 m), while it is not of such a definite physical significance as the foregoing, seems to form a convenient separation between groups of waves allocated by the Washington Regulations to services of quite different characters; |
