II LETTER OF TRANSMITTAL FEDERAL C01\-Il\IUNICATIO~S COMMISSION, WasMngton, D.O., Decembe>' 15, 1941. To the 00ngre88 of the United States: The Seventh Annual Report of the Federal Communications Com mission, submitted herewith, is brought up to date in major develop ments so that the Congress may bc more cnrrently informed about the Commission's national defense work and events in radio and wire regulation which have occurred since the fiscal year ended June 30 last. The war-time emergency and new considerations in the field of dec tricaI communications impose increasing and exaeting burdens on the Commission. The showing made has, in large measure, been possible by employee devotion to duty beyond that which might rensonably be expected, even in the face of unusual conditions.

NATIONAL DEFENSE OPERATIONS SECTION 3. FOREIGN BROADCAST MONITORING SERVICE 4. DEFENSE COMMUNICATIONS BOARD I. COMMISSION'S NATIONAL DEFENSE ACTIVITIES Solving the many comnlunicat-ions problems arising from the Na~ tion's defense effort is a primary concern of the Federal Cou1munica tions Commission. The rapid expansion of the Army and Navy, espe cially their air forces, the development of civilian defense plans and projects, the rise of new and perilous conditions on the high seas, the interruption of all direct cable service to the continent of Europe (the United Kingdom, Eire, and the Azores excepted), the need for ade quate presentation of United States broadcasts via short waves to other countries, especially in Latin America, the increase in telephone, tele graph, and radio communications traffic concurrent. with the defense program-these and a, variety of other developments during the past year have profoundly affected the day-to-day business of the Commis sion. No part of the Commission's work has been left unaffected by emergency requirements, and two new sections-the Natjona.! Defense Operations Section and the Foreign Broadcast Monitoring Service have been established to meet ('articular defense needs. Typical of the many CommIssion defense activities are the licensing of and granting addItional power to short-wave stations beamed on foreign countries; work with the Interdepartmental Committee on Cooperation with American Republics; the approval of 66 telegraph line-extension applications, 35 of which were for lines to military or naval establishments and one of which concerned a I,800-mile addi tion to the 30,OOO-mile weather-reporting system of the Civil Aero nautics Administration; special studies of our radiotelegraph links with other countries; rapid expansion of the channels available for aviation services, including special frequencies for aviation schools in connection with the Army's pilot-trainmg 'program; and a variety of technical studies and research projects dIrectly related to national defense needs. Details of these and other defense activities of the Com mission will be found throughout the various subdivisions of this report. 1 2 REPORT OF THE FEDERAL COMMUNICATIONS COMMISSIOK The defense progralll has 11lade necessary the expansion of plant .and equipment in a variety of communications fields; and the Commis sion has sought to expedite and facilitate such expansion in every ap propriate way. Shortages of strategic materials and skilled labor es sential to communications work have made it especially important to determine )vhich types of expansion are essential to present or antici pated defense reqmrements.
