Node-RED is a low-code graphical programming environment that connects Internet of Things (IoT) devices and software and enables machine-to-machine communications. Node-RED can easily interface to and control a wide array of dissimilar hardware, often using simple and inexpensive hardware interfaces. It’s low cost, allows for modifications from any web browser, and development time is relatively short, thanks to an ever-growing user community that’s willing to share their expertise. Hams are using Node-RED to facilitate remote operating, multi-multi contest operations, and more. Read QST

Just Released: More Arduino for Ham Radio
Written by popular author and experimenter Glen Popiel, KW5GP, this book introduces many of the new Arduino boards and add-on modules, followed by an overview of the software, tools, and techniques needed to bring projects to life. Practical projects showcase a wide variety of applications and include how the software “sketches” work. Buy Now
Back in Stock: End-Fed Half-Wave Antenna Kit
Perfect for HF and portable operating, this four-band end-fed half-wave (EFHW) antenna kit works on 10, 15, 20, and 40 meters. Building the kit is easy. You’ll drill, fasten, and solder. The advantage of an EFHW is the ease of construction, its versatility in a variety of installation configurations (sloping, horizontal, L, etc.), and no tuner is needed. We chose a 250-watt rated antenna so you can comfortably transmit the full output power from many off-the-shelf HF transceivers (typically around 100 watts). Buy Now
