Circa 1923:'A comprehensive and up to date collection of modern receiving and transmitting circuits with complete design data showing the electrical values of inductances, capacities and resistances with the name of each element on the diagram of the circuit. Each circuit has actually been tested and can be successfully built and operated when directions are followed. Includes explanations of wave length, frequency, tuning, antenna construction, fundamental coupling schemes and tells how to select manufactured parts. Note: This book is a reproduction of a manual written in 1923.
