ARRL has introduced three new e-books to its growing digital library. The newest titles available in the popular Amazon Kindle format include Work the World with JT65 and JT9 by ARRL author Steve Ford, WB8IMY, ARRL’s Small Antennas for Small Spaces, 2nd edition, and Antenna Physics: An Introduction, by Robert J. Zavrel, Jr, W7SX.

Work the World with JT65 and JT9 shows you how to assemble an effective digital communication station and configure the software for best performance. Some operators use these popular digital modes with as little as 5 watts RF output and an indoor antenna. The book is filled with tricks and tips to help you get on their air making contacts.

The fully updated, second edition of ARRL’s Small Antennas for Small Spaces is a must-have for radio amateurs who live in apartments, condominiums, or houses on small lots. The book is filled with practical advice, and will guide you to finding the right antenna design to fit whatever space you have available.

Antenna Physics: An Introduction was written to bridge the gap between basic theory and graduate-level engineering texts. Delve deeper into antenna theory, and explore the underlying principles, and mathematics, of antennas and antenna physics.

All of these publications are also available in a printed format, directly from ARRL and ARRL publication dealers.
