Things have changed since I wrote the first edition of 'SDR' in 2016. This updated edition places more emphasis on the latest SDR and hybrid radios and introduces some new ideas, such as the design of the QDX transceiver from QRP Labs. All the basic theory remains the same. Some radios have disappeared and some new ones have joined the list.
Everyone is talking about software defined radios. But is an SDR right for you? This book explains the basics without getting too technical. It will help you to get the most out of your new software defined radio or decide whether you want to buy one. The use of software defined radio by amateur radio operators and shortwave listeners is rapidly growing in popularity as people become aware of their great features and performance.
