Elektronica moeilijk? De titel van dit boek geeft het antwoord! In deze 3-in-1-band wordt de elektronica vanuit de praktijk benaderd. Dat wil zeggen veel praktijk in de vorm van experimenten en een minimum aan theorie. Zo raakt u stap voor stap vertrouwd met de behandelde onderwerpen. Daarbij ontstaan gaandeweg ook een flink aantal praktisch bruikbare schakelingen. Het gaat bij de elektronicahobby tenslotte om het bouwen of uitdenken van allerlei praktische of leuke schakelingen. Aan het eind van elk deel is een aanhangsel opgenomen met aanvullende informatie en de gegevens van een groot aantal elektronische componenten, zodat na dit boek ook eigen ideeën en experimenten kunnen worden aangepakt. In deze 3-in-1-band zijn de eerste drie delen uit de serie “Elektronica echt niet moeilijk” samengevoegd: Deel 1: experimenten met gelijkstroom Deel 2: experimenten met wisselstroom Deel 3: experimenten met digitale techniek

The QA403 is QuantAsylum's fourth-generation audio analyzer. The QA403 extends the functionality of the QA402 with improved noise and distortion performance, in addition to a flatter response at band edges. The compact size of the QA403 means you can take it just about anywhere. Features 24-bit ADC/DAC Up to 192 kS/s Fully isolated from PC Differential Input/Output USB powered Built-in Attenuator Fast Bootup and Driverless The QA403 is a driverless USB device, meaning it’s ready as soon as you plug it in. The software is free and it is quick and easy to move the hardware from one machine to the next. So, if you need to head to the factory to troubleshoot a problem or take the QA403 home for a work-from-home day, you can do it without hassle. No-Cal Design The QA403 comes with a factory calibration in its flash memory, ensuring consistent unit-to-unit performance. On your manufacturing line you can install another QA403 and be confident what you read on one unit will be very similar to the next unit. It is not expected that re-calibration will be required at regular intervals. Measurements Making basic measurements is quick and easy. In a few clicks you will understand the frequency response, THD(+N), gain, SNR and more of your device-under test. Dynamic Range The QA403 offers 8 gain ranges on the input (0 to +42 dBV in 6 steps), and 4 gain ranges on the output (-12 to +18 dBV in 10 dB steps). This ensures consistent performance over very wide ranges of input and output levels. The maximum AC input to the QA403 is +32 dBV = 40 Vrms. The maximum DC is ±40 V, and the maximum ACPEAK + DC = ±56 V. Easy Programmability The QA403 supports a REST interface, making it easy to automate measurements in just about any language you might anticipate. From Python to C++ to Visual Basic—if you know how to load a web page in your favorite language, you can control the QA403 remotely. Measurements are fast and responsive, usually with dozens of commands being processed per second. Isolated and USB Powered The QA403 is isolated from the PC, meaning you are measuring your DUT and not chasing some phantom ground loop. The QA403 is USB powered, like nearly all our instruments. If you are setting up remotely, throw a powered hub in your bag and your entire test setup can be running with a minimum of cables. Goodbye Soundcard, Hello QA403 Tired of trying to make a soundcard work? The calibration nightmare? The lack of gain stages? The limited drive? Are you tired of dealing with the fixed input ranges? The worry that you might destroy it with too much DC or AC? Tired of the ground loops? That’s why QuantAsylum built the QA403.

Opera Cake is an antenna switching add-on board for HackRF One/Pro that is configured with command-line software either manually, or for automated port switching based on frequency or time. It has two primary ports, each connected to any of eight secondary ports, and is optimized for use as a pair of 1x4 switches or as a single 1x8 switch. Its recommended frequency range is 1 MHz to 4 GHz. When HackRF One/Pro is used to transmit, Opera Cake can automatically route its output to the appropriate transmit antennas, as well as any external filters, amplifiers, etc. No changes are needed to the existing SDR software, but full control from the host is available. Opera Cake also enhances the HackRF One/Pro’s use as a spectrum analyzer across its entire operating frequency range of 1 MHz to 4 GHz. Antenna switching works with the existing hackrf_sweep feature, which can sweep the whole tuning range in less than a second. Automatic switching mid-sweep enables the use of multiple antennas when sweeping a wide frequency range. Downloads Documentation GitHub

Program and build Raspberry Pi based ham station utilities, tools, and instruments The improved RTL-SDR V4 allows you to receive radio signals between 500 kHz and 1.75 GHz from stations utilizing different bands including MW/SW/LW broadcast, ham radio, utility, air traffic control, PMR, SRD, ISM, CB, weather satellite, and radio astronomy. The book Raspberry Pi 5 for Radio Amateurs gives extensive coverage of deploying the RTL-SDR kit through the use of a Raspberry Pi 5. This bundle contains: RTL-SDR V4 (incl. Dipole Antenna Kit) (normal price: €75) Raspberry Pi 5 for Radio Amateurs (normal price: €40) RTL-SDR V4 (Software Defined Radio) with Dipole Antenna Kit RTL-SDR is an affordable dongle that can be used as a computer-based radio scanner for receiving live radio signals between 500 kHz and 1.75 GHz in your area. The RTL-SDR V4 offers several improvements over generic brands including use of the R828D tuner chip, triplexed input filter, notch filter, improved component tolerances, a 1 PPM temperature compensated oscillator (TCXO), SMA F connector, aluminium case with passive cooling, bias tee circuit, improved power supply, and a built in HF upconverter. RTL-SDR V4 comes with the portable dipole antenna kit. It is great for beginners as it allows for terrestrial and satellite reception and easy to mount outdoors and designed for portable and temporary outside usage. Features Improved HF reception: V4 now uses a built-in upconverter instead of using a direct sampling circuit. This means no more Nyquist folding of signals around 14.4 MHz, improved sensitivity, and adjustable gain on HF. Like the V3, the lower tuning range remains at 500 kHz and very strong reception may still require front end attenuation/filtering. Improved filtering: The V4 makes use of the R828D tuner chip, which has three inputs. The SMA input has been triplexed input into 3 bands: HF, VHF and UHF. This provides some isolation between the 3 bands, meaning out of band interference from strong broadcast stations is less likely to cause desensitization or imaging. Improved filtering x2: In addition to the triplexing, the open drain pin on the R828D can be also used, which allows to add simple notch filters for common interference bands such as broadcast AM, broadcast FM and the DAB bands. These only attenuate by a few dB, but may still help. Improved phase noise on strong signals: Due to an improved power supply design, phase noise from power supply noise has been significantly reduced. Less heat: Another advantage of the improved power supply is low power consumption and less heat generation compared to the V3. Included 1x RTL-SDR V4 dongle (R828D RTL2832U 1PPM TCXO SMA) 2x 23 cm to 1 m telescopic antenna 2x 5 cm to 13 cm telescopic antenna 1x Dipole antenna base with 60 cm RG174 1x 3 m RG174 extension cable 1x Flexible tripod mount 1x Suction cup mount Downloads Datasheet User Guide Quick Start Guide SDR# User Guide Dipole Antenna Guide Book: Raspberry Pi 5 for Radio Amateurs 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.
