Radio Today Guide To The Icom IC-7300MK2
Radio Today Guide to the Icom IC-7300MK2 By Andrew Barron, ZL3DW Since its introduction in 2016, the Icom IC-7300 has become one of the most popular transceivers in amateur radio. Building on the success of the original, the new IC-7300MK2 introduces enhanced performance, updated specifications, and new features that further elevate this industry-leading radio. In this comprehensive guide, renowned author and amateur radio operator Andrew Barron, ZL3DW provides practical, easy-to-follow instruction to help operators get the most from their IC-7300MK2. The original IC-7300 brought advanced technologies previously found only in much more expensive transceivers to a wider audience. The IC-7300MK2 builds upon that legacy with notable receiver and transmitter performance improvements, including enhanced Reciprocal Mixing Dynamic Range (RMDR) and reduced transmitted phase noise. These improvements help the radio better handle strong nearby signals, resulting in improved operating performance in crowded band conditions. New features include an integrated CW decoder, reduced heat generation through revised circuitry and DC power optimization, and an HDMI output that provides both video and audio for external displays. The radio's popular 4.3-inch touchscreen has also been upgraded from a TFT LCD to an IPS (In-Plane Switching) display, delivering improved color accuracy, wider viewing angles, higher contrast, sharper image quality, and faster response times. As with all Radio Today guides, this book goes far beyond simply repeating the information found in the owner's manual. Instead, it focuses on practical setup, operation, and optimization of the radio's many capabilities. Readers will find detailed guidance on configuring operating modes, setting up digital communication software such as FT8, troubleshooting common issues, and unlocking the full potential of the IC-7300MK2. Whether you already own the Icom IC-7300MK2 or are considering adding one to your station, the Radio Today Guide to the Icom IC-7300MK2 is an invaluable resource filled with practical advice, expert insights, and real-world operating knowledge that will help you get the most from this exceptional transceiver.

EMC and RFI Know How
Many radio amateurs have Electromagnetic Compatibility (EMC) issues or, as it is more commonly referred to in the US, Radio Frequency Interference (RFI). As a scourge of our time, there's been much written about this topic as to cures, identifying the problems, and much more. "EMC and RFI Know-How" sets out to draw this material together and provide valuable insight into an area considered by many to be one of the most important problems facing amateur radio today. This 208-page paperback draws on expertise from across the world and includes material from the UK, USA, Germany, Greece, and the Netherlands. You'll find sections dedicated to sources of interference such as lighting, xDSL, renewable energy, air conditioners, air source heat pumps, power line noise, and power supplies and chargers. "EMC and RFI Know-How" also takes the reader through practical ways of defeating the problem of interference. Home constructors are well catered for with the circuit of an HF receiver suitable for direction-finding, a preselector to eliminate interference from powerful broadcast stations, filters to stop breakthrough to TVs, and even a 'QRM-Eliminating' antenna. Advice is also given on how to prevent breakthrough from amateur transmissions spoiling the family's enjoyment of television programs! The average home contains numerous electronic devices that can potentially cause interference in the amateur radio spectrum. "EMC and RFI Know-How" takes a detailed look at how this interference can occur—and how it can be defeated. This an essential book for every radio amateur's library.

Portable Antennas for Everyone
Portable operating has never been as popular as it is today, thanks to the many excellent modern, small, and lightweight transceivers that are available. But indoors or outside, any station is only as good as its antenna, and that's where this book comes in. "Portable Antennas for Everyone" is broken into sections covering the main types of antenna. Specific designs from around the world are included, starting with a fiberglass pole and a simple 10m length of wire attached to make a quarter-wave vertical antenna for 7MHz. The 192-page paperback continues into verticals designed specifically for use by the ocean and that provide a super-low angle of radiation of just 6 or 7 degrees above the horizon. This book describes how to make a vertical dipole array (VDA), and there's some good advice on kite-supported verticals. You'll also see designs for HF dipoles, doublets, and making your own lightweight HF beams. VHF and UHF antennas are not forgotten: the book includes a dual-band Yagi for satellite working, collapsible 2m and 6m beams, a roll-up J-pole, a 70cm Lindenblad antenna, and even a dual-band beam made from tape measures. Read reviews of commercially made antennas for portable operations—such as the Spiderbeam, the ultra-lightweight Hexbeam, the folding Hexbeam, the all-band SuperStick, an easily transportable magnetic loop, and much, much more. If you're suffering from high domestic noise levels at home, operating portable from the countryside can be a real revelation. Often there is no local noise whatsoever and you find you can copy S1 signals with ease. So now there's no excuse: "Portable Antennas for Everyone" allows everyone to get on the air while experiencing the great outdoors!

QRP Scrapbook
Low-power operation, or QRP, is one of the most popular aspects of amateur radio—and the UK's G-QRP Club is a leading light in this area. This book draws together the very best articles from authors around the world that have been published in the club's journal, SPRAT, in recent years. Packed with projects, "QRP Scrapbook" contains all-new material not previously published in an Radio Society of Great Britain (RSGB) book. Much is included in this 240-page paperback, including modern techniques like a practical RF generation system for superhets using direct digital synthesis (DDS) modules, the use of TV 'dongles' to make a software defined radio (SDR), plus Arduino microcontroller projects for a CW transceiver and keyer, and much more. "QRP Scrapbook" has six sections covering QRP transmitters and transceivers; simple and also somewhat more complex receivers; antenna systems and test equipment suitable for low-power operation—and a 'miscellaneous' section covering subjects as diverse as how to wind toroids tidily, making your own ribbon cable, Morse keys and keyers, crystal oscillators, and ceramic resonators. With the increasing problem of local interference, the noise-cancelling device in this section will be of interest to all amateurs, not just those who operate with low power. Produced in co-operation between the RSGB and the G-QRP Club, this book is essential reading for all interested in the latest in home-construction techniques and the art and science of low-power amateur radio.
