This revision of a best-selling, practical handbook on land mobile radio systems will enable readers to understand and apply the tremendous changes brought on by integrated circuits, microprocessors, computers, digital technology, and satellites. It integrates the new technologies with basic information on many different land mobile radio systems, and gives solutions to prevent very frustrating intermittent system failures. This edition brings readers up to date with technologies such as computers, digitized voice, second generation trunking, second generation simulcasting, amplitute compandored single sideband, second generation cellular, automatic vehicle location (including GPS), and satellitesand demonstrates how the technologies are used in land mobile radio systems. For those who work in the field of land mobile radio, including radio mechanics, radio engineers, directors of communications.
