Description

Handbook for Radio Engineering Managers deals with management, organization, engineering economy, safety practices, fires, environmental aspects, specifications, and contract administration of projects. The text explains project management concerning initiation of the planning and design stages, establishment of controls, staffing supervision, installation work, commissioning, and turnover to the operating and maintenance staff. Engineering economy involves cost/benefit analysis, preparation of budget for new installations, maintenance, and repairs. The book also discusses safety practices such as staff responsibilities, aid facilities, electrical or radio equipment, radiation hazards, maintenance of mast and towers. The text discusses fires in radio installations, fire detecting facilities, transformer problems, lighting hazards, and electric shock hazards. The environmental aspects in radio engineering include equipment or materials performance, corrosion, structural failures, environmental obligations in mast or tower design, as well as radio frequency spectrum management. The radio engineering manager should also be knowledgeable regarding specifications and contract administration covering radio engineering specifications, inspection, acceptance tests, and contract administration. The methods and practices explained in the book are applicable for large, medium, or small sized stations or project. The book is a useful reference for radio station managers, radio station technicians, radio engineers, electrical engineers, and for administrators of radio stations or other communications facilities.
