The ARRL has released two new books: Ham Radio for Arduino and PICAXE edited by Leigh L. Klotz Jr, WA5ZNU, and Radio Science for the Radio Amateur by Eric Nichols, KL7AJ.

Ham Radio for Arduino and PICAXE
Microcontroller technology has exploded in popularity among ham radio operators. The new generation of single-board microcontrollers is easier than ever to use, bringing together hardware and software for project building that radio amateurs can easily dive into. With inexpensive microcontroller platforms -- such as the popular open-source Arduino board -- readily available parts, components and accessory boards, you can create beacon transmitters, keyers, antenna position control, RTTY and digital mode decoders, waterfall displays and more.

Editor Leigh L. Klotz Jr, WA5ZNU, has assembled this first edition of Ham Radio for Arduino and PICAXE to help introduce radio amateurs to the fun and rewards of experimenting with microcontrollers. Klotz and other contributors have designed projects that will enhance your ham radio station and operating capabilities, or you can use these projects as a launch pad for creating your own projects.

Radio Science for the Radio Amateur
In Radio Science for the Radio Amateur, Eric Nichols, KL7AJ, explores and explains the often profound differences between science and technology, dispelling the notion that we know all there is to know about radio. Using a fresh, playful approach, Nichols guides readers through some of the most fascinating “nooks and crannies” of the radio universe. Along the way, you’ll find out how solving long-standing mysteries of radio -- of which there are still many -- doesn’t require expensive hardware, but merely a scientific mindset and attention to detail.
