Program and Build Raspberry Pi 5 Based Ham Station Utilities with the RTL-SDR The RTL-SDR devices (V3 and V4) have gained popularity among radio amateurs because of their very low cost and rich features. A basic system may consist of a USB based RTL-SDR device (dongle) with a suitable antenna, a Raspberry Pi 5 computer, a USB based external audio input-output adapter, and software installed on the Raspberry Pi 5 computer. With such a modest setup, it is possible to receive signals from around 24 MHz to over 1.7 GHz. This book is aimed at amateur radio enthusiasts and electronic engineering students, as well as at anyone interested in learning to use the Raspberry Pi 5 to build electronic projects. The book is suitable for both beginners through experienced readers. Some knowledge of the Python programming language is required to understand and eventually modify the projects given in the book. A block diagram, a circuit diagram, and a complete Python program listing is given for each project, alongside a comprehensive description. The following popular RTL-SDR programs are discussed in detail, aided by step-by-step installation guides for practical use on a Raspberry Pi 5: SimpleFM GQRX SDR++ CubicSDR RTL-SDR Server Dump1090 FLDIGI Quick RTL_433 aldo xcwcp GPredict TWCLOCK CQRLOG klog Morse2Ascii PyQSO Welle.io Ham Clock CHIRP xastir qsstv flrig XyGrib FreeDV Qtel (EchoLink) XDX (DX-Cluster) WSJT-X The application of the Python programming language on the latest Raspberry Pi 5 platform precludes the use of the programs in the book from working on older versions of Raspberry Pi computers.

Ocean Sound Generator The Elektor Surf Synthesizer convincingly imitates the sound of breaking waves. It is based on a circuit published in the 1972 summer edition of Elektor to celebrate the Summer Olympics held that year in Munich, Germany. The Surf Synthesizer can be considered a real analog music synthesizer, as it follows the paradigm of voltage-controlled subtractive sound synthesis made popular by Robert Moog and friends (remember the Elektor Formant?). Instead of a VCO (voltage-controlled oscillator), it has a noise generator as a sound source. A VCF (voltage-controlled filter) and a VCA (voltage-controlled amplifier) modulated by three LFOs (low-frequency oscillators) shape the sound of the waves. The Surf Synthesizer comes as an easy-to-build kit using only through-hole components. The kit contains all the required parts, including a stylish wooden stand. First mount all the parts on the front side (showing the schematic). Terminate by mounting the battery holder on the backside (showing the circuit description). The use of headphones (not included) is recommended for obtaining the best sound quality. A 9 V (PP3) battery (not included) powers the Surf Synthesizer.
