  • The Microwave System of the Michigan-Wisconsin Pipeline Company

    It is perhaps unnecessary to point out to the reader that in the design of a communication network, such as the Michigan-Wisconsin Pipeline microwave-VHF system, which includes 60 microwave stations, the incorporation of the desired operating features into the system is often a more complex and demanding engineering task than the design of the basic circuit elements. The provision of maximum flexi... View full abstract»

    This article discusses a method by which microwave systems are laid out in rugged undeveloped country, where maps alone cannot be used to indicate path clearance. The first step is to gather all available information and, by careful study of the topography, to lay out several possible microwave routes. The next step is to conduct a methodical low level aerial survey by means of inexpensive light a... View full abstract»

  • Microwave Repeater Site Planning and Development

    In the overall planning of a microwave system the propagation experts must work in conjunction with the site development engineers. The site development group will require the services of civil and mechanical engineering consultants. These people should operate together in choosing each and every site so that propagation versus site development economics can be compared at every step. For the purp... View full abstract»

  • Remote Control of Standby Engine Generator Sets Over a Microwave System

    Experience in actual operation of microwave relay systems throughout the country has shown that involuntary outages have been caused principally by failure of the input power to the microwave equipment. Where substantially continuous service is required of the microwave system the common practice is to have emergency standby power available. This emergency power is supplied by an emergency generat... View full abstract»

  • Application of Compandors to FM Radio Systems with Frequency Division Multiplexing

    Publication Year: 1954, Page(s):36 - 40

    Compandors are used to improve the intelligibility of speech transmission circuits by increasing the signal-to-noise ratio. Originally developed in the early 1930's for use with transoceanic radio circuits, they have since been applied to some extent on long distance telephone circuits, usually of the carrier-derived type. Within the past few years new telephone carrier systems have been developed... View full abstract»

    Microwave communications is one of today's most rapidly expanding fields in the radio art. Its inherent characteristics fit well into the communication needs of expanding industry. One of its important advantages over conventional communication means is the capability of handling numerous voice frequency channels over a single radio frequency carrier. This capability is made possible by the wide b... View full abstract»

  • A Microwave System for Trunk Service

    Publication Year: 1954, Page(s):50 - 59
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1505 KB)

    The system described in this paper was designed to provide trunk facilities for telegraph purposes. The accumulated experience of the Telegraph Company's New York-Washington-Pittsburgh radio relay triangle was of value in the early stages of planning. This commercial service, which was installed in the latter part of 1946 and placed in operation early in 1948, highlighted many of the problems that... View full abstract»

  • A Microwave Radio System for Pipeline Use

    In the Texas-Illinois pipeline installation of a microwave relay, the reliability problem was emphasized by the distribution of some 2000 vacuum tubes and associated other components over more than a thousand miles of pipeline right-of-way. The general solution to the reliability problem was threefold, including the design of inherently reliable equipment, provision of full automatic switchover to... View full abstract»

    The prime function of any electric utility is that of reliable and uninterrupted power flow to its customers. The direct relation between the growth of a utility and the expansion of its communication facilities often times do not parallel. This results in the communications facilities becoming so overburdened that they almost become ineffective. Figure 1 shows Union Electric's growth over the pas... View full abstract»

  • Microwave Radio Relay Link for Military Use

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (606 KB)

    Radio set AN/TRC-29 is the nomenclature for a frequency-modulated microwave radio link equipment designed for military use. It transmits in the band from 1700 to 2400 megacycles and will accept input signals between 30 cycles and 4.5 megacycles. In most cases, It will probably be used in conjunction with Multiplexer Set AN/TCC-13. This latter unit, which will also be described, is a pulse-position... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (389 KB)

    The Transco system is approximately 1,780 miles in length and has roughly 9,350 circuit miles in use, all of which are for voice conversation. Our main system consists of 59 stations placed at intervals of 30.7 miles, with the shortest hop 10 miles and the longest 50 miles. Tower heights range from 50 to 350 feet, generally supporting two 6' dishes. The backbone equipment was manufactured by Gener... View full abstract»

  • Microwave Testing with Millimicrosecond Pulses

    Publication Year: 1954, Page(s):93 - 99

    Pulse testing techniques have been used for many purposes for a long time. In studies of waveguides as radio and radar components and for possible communications systems use, we have employed various types of pulse testing. The need for greater resolution through the use of very short pulses has always been apparent. For this reason, equipment has recently been built to generate and display 9,000 ...

  • Theoretical Aspects of Microstrip Waveguides

    Publication Year: 1954, Page(s):100 - 102

    The Microstrip is a modification of the wire-above-ground system of transmission - the wire is replaced by a narrow strip printed on a dielectric sheet which is backed by a conductor. An exact theory for such a structure is difficult because the cross section is not homogeneous and has a geometry which does not lead to separation of variables. Furthermore it is an "open" structure where the energy... View full abstract»

  • Considerations in Klystron Design for Microwave Relay Systems

    Publication Year: 1954, Page(s):103 - 107
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (602 KB)

    When a new relay system is being considered, there are many decisions to be made about the type of system and the tube to generate the power. A system which employs a klystron power mixer has many advantages. One of them being that all video amplifiers are eliminated except one at each of the terminals. Furthermore there are no modulation processes that cause amplitude non-linearity in any of the ... View full abstract»
