摘要

This report describes the development of an ultra-high-frequency two-course visual radio range with sector identification and simultaneous voice. It treats the basic principles of the various components of this type of range, such as the mechani¬cal modulator, radio-frequency bridges, antenna systems, and tie lines.nThe latter part of the report covers further simplification of the antenna system and various methods of applying simultaneous voice to this range. A naviga¬tional aid was developed which provided two visual courses, two aural courses to give sector identification, station identification, and a simultaneous voice feature for weather information and airway traffic control. The receiving and transmitting equip¬ment which was used in this development is described, and the results of flight tests are given.
