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 radio amateurs can easily dive into. Ham Radio for Arduino and PICAXE introduces you to the fun and rewards of experimenting with microcontrollers. Editor Leigh L. Klotz Jr, WA5ZNU, and many other contributors have designed projects that will enhance your ham radio station and operating capabilities. Or, take it to the next step, using these projects as a launch pad for creating your own projects APRS Data Logger QRSS Beacon Multimode Transmitter Shield High Voltage, High Frequency, and High Temperature Data Logger Receive-Only, Low-Power APRS iGate PICAXE Keyer and CW Beacon Keyer Solar Tracker Nanokeyer Handheld Radio Talk Timer APRS Messenger DTMF Controlled SSTV Camera APRS Display Waterfall SWR Scanner
