Books with author Andrew Barnes

Winner of The Green Prize for Sustainable LiteratureA Finalist for the PEN/Bograd Weld Prize for BiographyFour influential women we thought we knew well—Jane Jacobs, Rachel Carson, Jane Goodall, and Alice Waters—and how they spearheaded the modern progressive movementThis is the story of four visionaries who profoundly shaped the world we live in today. Together, these women—linked not by friendship or field, but by their choice to break with convention—showed what one person speaking truth to power can do. Jane Jacobs fought for livable cities and strong communities; Rachel Carson warned us about poisoning the environment; Jane Goodall demonstrated the indelible kinship between humans and animals; and Alice Waters urged us to reconsider what and how we eat. With a keen eye for historical detail, Andrea Barnet traces the arc of each woman’s career and explores how their work collectively changed the course of history. While they hailed from different generations, Carson, Jacobs, Goodall, and Waters found their voices in the early sixties. At a time of enormous upheaval, all four stood as bulwarks against 1950s corporate culture and its war on nature. Consummate outsiders, each prevailed against powerful and mostly male adversaries while also anticipating the disaffections of the emerging counterculture. All told, their efforts ignited a transformative progressive movement while offering people a new way to think about the world and a more positive way of living in it.

This book is intended for Amateur Radio Operators, Shortwave Listeners, and anyone interested in radio as a hobby. It includes sections on how different types of software defined radios work, the advantages of using them, and how they are tested. It also covers future trends including the development of Direct Fourier Conversion. There is a big section with tips for PowerSDR users and sections about other commonly used SDR software, plus a comparison of the basic specifications of 65 different SDR receivers and transceivers. The book is not a textbook or a reference book. It is written in an easy to read conversational style. I explain the basics without getting too technical. There are no pages of software code or complex mathematics. I find that simple diagrams can often make things easier to understand so I have included some helpful drawings and photographs. The book contains sections on: •What to look for when buying an SDR•What is different about SDR?•What computer skills do you need?•What is digital? – a brief recap on digital theory•Definitions of software defined radio•Generations and types of SDR•Are SDRs better?•Future trends•Common questions about SDR •SDR software on the PC•Audio connections for digital modes•SDR for shortwave listening, CW, digital modes, contesting, interference monitoring, EME, microwave, and satellite operation•SoftRock, Genesis radios, RTL dongle, FUNcube dongle, USB connected receivers, USRP, Noctar, HackRF and Blade RF•SDRs with knobs•On-board or external DSP?•FlexRadio Systems transceivers and SmartSDR•Apache Labs ANAN transceivers and PowerSDR•cuSDR, KISS Konsole, SDR#, and GNU radio software•I and Q signals, Quadrature sampling, Direct Digital Synthesis, Direct Fourier Conversion•The ADC, The FPGA or microcomputer, Server / Client architecture, FFT magic, DSP, Panadapter and waterfall displays•Radio performance testing•Catalog of Software Defined radios – a comparison of 65 SDR receivers and transceivers•Glossary of abbreviations and acronyms•List of drawings and images

Amsats and Hamsats provides a comprehensive guide to how you can communicate through amateur radio satellites and how to receive signals from other small satellites and 'weather' satellites. The book gets right into the techniques you will need for working amateur radio stations through amateur radio satellites, then moves on to listening, or watching, signals from other satellites. There are chapters answering questions like, ‘how do satellites stay in orbit’ and ‘why are they so expensive to launch?’ Followed by sections about the history of amateur radio satellites, the mathematics governing orbits, TLE files, different types of satellite and their orbits. The book covers the equipment you need, to track and use the amateur satellites and some of the satellite tracking software that is available. There are detailed sections covering transponders, satellite bands, feeders, masthead preamplifiers, antenna systems and automated rotator control. Plus chapters on the FUNcube Satellites, Weather Satellites and even the International Space Station. Amsats and Hamsats provides the ultimate guide to operating satellites and how they work. Its 368 pages are a great value guide to this stimulating and challenging area of amateur radio activity. If you want to get started, or you are already an experienced operator you will find something of value in these pages.
