QST’s monthly “Product Review” column has long been the most-read section of the magazine. That’s not surprising, as most radio amateurs are interested in reading about the latest station equipment, and product review testing helps operators make informed decisions based on their needs and desired performance.
Amateur Radio Transceiver Performance Testing explains in detail the performance data tables from QST Product Reviews. It discusses how published laboratory data relates to actual performance, how each major test is performed, the significance of each test, and what the numbers mean. After reading this book, you’ll gain a better understanding of the extensive testing ARRL performs, learn the technical terms and parameters presented in Product Review, and develop the capability to reach your own conclusion about which HF transceiver is best for you.
General Specifications – Each Product Review data table begins with a section of general specifications, including transmit and receive frequency coverage, mode(s) of operation and power supply requirements. Receiver Performance – Receiver performance tests show how well the receiver hears signals of various strengths and how well it can reduce or eliminate undesired effects from strong adjacent signals. Transmitter Performance – Transmitter tests show how much power the transmitter puts out on various modes, its CW keying characteristics and SSB signal cleanliness, and how well it meets FCC emissions requirements. …and more!
