A new ultrahigh-frequency multichannel military radio relay system

MANY items must be studied in designing a new radio set, and a large amount of information and data must be obtained which can therefore be exhibited. However, the practical confines of this paper make it possible to cover only in a general way the major items which may be of interest to other development engineers. Accordingly, this paper will first outline what the new military radio relay equipment does and what it consists of; then briefly describe the circuits of the major units; after which much of the text will cover the important and difficult problems of distortion and noise which so directly affect multichannel systems performance; and will close with a few remarks concerning some of the systems' problems and their solutions. In a companion paper V. I. Cruser1 describes the many equipment features of this radio set.
