Programming with GNU Radio HackRF is an open-source hardware platform developed by Great Scott Gadgets and serves as a versatile front end for software-defined radio (SDR). With HackRF One and its successor, HackRF Pro, users can develop their own SDR applications, build powerful receivers and transmitters, and tackle demanding RF measurement tasks. This book provides a practical introduction to the world of SDR. Step by step, the author shows how powerful SDR projects can be implemented with HackRF – from the fundamentals of RF technology to advanced applications using GNU Radio. In addition to working with SDR Sharp (SDR#), RadioConda, and GNU Radio, the book also covers the fundamentals of modern digital signal processing. Numerous experiments and easy-to-follow practical examples guide readers through topics such as AM, FM, and SSB reception, digital filters, shortwave radio, amateur radio, signal generators, and custom RF projects up to 6 GHz. Whether you are a maker, radio amateur, electronics enthusiast, or SDR beginner, this book provides solid knowledge, practical applications, and the motivation to creatively explore the possibilities of modern SDR technology.

Met ringkern-uitgangstranformatoren Buizenversterkers vormen voor velen het neusje van de zalm, wanneer het gaat om de versterking van audiosignalen. De combinatie van klassieke techniek met moderne componenten heeft geleid tot een ware revival van de buizenversterker. De toepassing van de in de afgelopen 15 jaar door de auteur ontwikkelde 'ringkern-uitgangstransformatoren' heeft daar mede toe bijgedragen. Opvallend aan deze transformatoren zijn vooral het extreem grote frequentie bereik en de geringe lineaire en niet-lineaire vervormingen. Het hoe en waarom van de transformator wordt op verschillende niveaus uitgelegd, beginnend bij inleidende begripsvorming en eindigende bij complete wiskundige beschrijvingen, waarbij ook de samenwerking van de transformator met de buizen en de luidspreker centraal staat. Naast de beschrijving van schematuur en zelfbouw van eenvoudig na te bouwen moderne high-end buizenversterkers met een uitgangsvermogen van 10 tot 100 Watt, worden bijzondere buizenversterkers met ringkerntransformatoren besproken: innovatieve oplossingen voor perfecte audiokwaliteit. Zowel de zelfbouwer als degene die kennis en inzicht wil verwerven in de complexe materie van transformatoren, buizenversterkers en audiosignaalverwerking zal dit boek met plezier ter hand nemen.
