Abstract :
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 are encountered with this transmission medium.
