HF radio propagation predictions are calculated for 35 circuits from the Voice of America transmitting facility at Tinang, P. I. and 30 circuits from their facility at Kava1a, Greece, using the OT/ITS prediction program. The program selects the optim...
VOLUME I: HF radio propagation predictions are calculated for Voice of America circuits using the OT/ITS prediction program. Some of the parameters given are maximum usable frequency, the optimum traffic frequency, the lowest useful frequency, avail...
Telecommunications has had and increasingly continues to have a very significant and pervasive impact upon the international relations between the United States and other countries throughout the world. Probably the most important measure of this im...
This paper discusses the historical development of OT including: when each element was formed, the motivation behind its formation and in relation to the overall OT development; the size of each element; the basic function each element was to fulfil...
A review of telecommunications technology and an assessment of possibilities for its use as a substitute for travel. The basic objective is to provide knowledge that will explore the various uses of telecommunications as it affects transportation [s...
A generally accepted spectrum use metric (unit of spectrum-space use) would expedite efficient allocation and management of the spectrum resource. It would be useful for quantitative studies of spectrum congestion, and for economic analysis of the re...
This report contains a summary of work performed for the United States Information Agency, Voice of America, under contract IA-16129-23 for the period July 1972 through June 1973.
Coast Guard stations on the West Coast of the United States provide adequate 500 kHz coverage of the ocean within 300 miles of the shore, except possible for some regions around northwest Alaska.
A computer procedure is described which provides a map of population and/ or housing units. Another procedure finds the population within arbitrary circles. The data base is the 1970 Master Enumeration District List, with coordinates, furnished by t...
HF radio propagation predictions are calculated for Voice of America circuits using the OT/ITS prediction program. Some of the parameters given are maximum usable frequency (MUF), the optimum traffic frequency (FOT), the lowest useful frequency (LUF...
M. F. broadcasting from. so-called "pirate" radio stations has plagued many of the advanced countries of the world. With the final disposition of the WXUR case in June 1973, Dr. Carl McIntire appears to be making good his proposal to resume broadcast...
HF radio propagation predictions are calculated for Voice of America circuits using the OT/ITS prediction program. Some of the parameters given are maximum usable frequency (MUF), the· optimum traffic frequency (FOT), the lowest useful frequency (LU...
HF radio propagation predictions are calculated for circuits from the Voice of America transmitting facility at Tinang, P. I. and 25 circuits from their facility at Kavala, Greece, using the OT/ITS prediction program. The program selects the optimum...
This document is a user’s manual for a program to compute and plot equipotential power flux density contours on the earth's surface from a satellite-borne antenna. The computer output is microfilm plots of the contours on earth maps showing continen...
A novel, five-wire, rhomboid-shaped Beverage developed at Rome Air Development Center, Griffiss AFB, is examined from the standpoint of its applicability to HF, over-the-horizon radar. Both receiving and transmitting applications are considered. The ...
