SDR接收机的设计与实践
SDR接收机的设计与实践SDR接收机的设计与实践近年来，软件定义无线电（Software Defined Radio，简称SDR）技术得到了广泛应用和持续发展。
SDR接收机作为SDR系统的重要组成部分，在通信、无线电频谱监测、雷达、无线电干扰分析等领域具有广泛的应用前景。
本文将介绍SDR 接收机的设计原理、实践经验以及相关应用案例。
一、SDR接收机的设计原理SDR接收机的核心思想是将传统的无线电硬件功能移入软件，通过数字信号处理对射频信号进行取样、滤波、解调等处理。
其设计原理主要包括前置放大、模拟-数字转换、滤波和解调等关键步骤。
1. 前置放大SDR接收机中的前置放大器负责将输入信号的电平增益至适宜的范围，以提高接收灵敏度和动态范围。
在设计前置放大器时，需要考虑增益平坦性、噪声系数和非线性失真等关键指标，并根据应用场景选择合适的放大器类型。
2. 模拟-数字转换模拟-数字转换是SDR接收机的重要环节，用于将收到的模拟信号转换为数字信号进行后续处理。
传统的模拟-数字转换器（ADC）采用采样保持电路将连续的模拟信号转换为离散的数字信号。
在设计中，需要根据所需的带宽、采样率和分辨率等要求选取适当的ADC芯片。
3. 滤波滤波是SDR接收机中的重要环节，用于抑制带外噪声和无用信号，使得后续的数字信号处理更加精确和高效。
一般使用低通滤波器对采样后的信号进行滤波处理，以滤除高频噪声和混频产生的谐波等不必要信息。
4. 解调解调是SDR接收机的关键环节，用于从接收信号中恢复出原始的信息信号。
不同的调制方式需要采用不同的解调算法，常见的解调方式包括调幅解调、调频解调、调相解调等。
解调算法的选取需要根据具体的应用场景和系统需求进行优化。
二、SDR接收机的实践经验在实践中，设计和实现一个高性能的SDR接收机需要多个方面的综合考虑。
以下是一些关键的实践经验和技巧：1. 选择适当的硬件平台：根据应用需求和性能要求，选择合适的硬件平台，如通用计算机、FPGA、DSP、ARM等。

详解：软件无线电（SDR）发射和接收过程
详解：软件无线电（SDR）发射和接收过程常规的外差式无线电接收器已经使用了近一个世纪，如图所示。
我们再次回顾一下模拟接收器的结构，以便于和数字接收器进行比较。
首先，来自天线的射频信号被放大，通常射频部分利用一个调谐器将感兴趣的频段区域的信号进行放大。
这个放大的射频信号被送入一个混频器。
来自本振的信号也被送入混频器，其频率由无线电的调谐控制决定。
混频器将所需的输入信号转换为中频，如图所示。
中频部分是一个带通放大器，只允许一个信号或者无线电台通过。
常见的中心频率是455kHz和10.7MHz，用于商业的AM和FM广播。
解调器从几个不同的方案中选择一个，将中频输出信号还原成初始调制信号。
例如，AM利用包络检波器，FM利用频率鉴别器。
在一个典型的家用收音机中，解调后的输出信号被送入到一个音频功率放大器，驱动一个扬声器。
混频器对两个输入信号进行模拟相乘，生成一个差频信号。
通过设置本振频率，从而使得本振频率与想要的输入信号（你想要接收到的无线电台）的差值等于中频。
例如，你想接收频率为100.7MHz的调频电台，中频为10.7MHz，你需要将本振调整至：此过程称作“下变频”，因为一个高频信号通过混频器下移到低频率。
中频部分的作用相当于一个窄带滤波器，只允许被转换后的射频输入的一个“片段”通过。
中频部分的带宽等于你试图接收到的信号（或者“无线电台”）的带宽。
商业调频电台的带宽大约为100kHz，调幅电台带宽为5kHz，分别对应相应的频道间隔200kHz和10kHz。
软件无线电接收器软件定义的无线电接收器框图如图所示。
射频调谐器将模拟射频信号转换为模拟中频，与模拟接收器的前三个阶段相同。
接下来，A/D转换器将中频信号数字化，从而将其转换成数字样点。
这些样点被送入下一级，即图中虚线框所示的数字下变频（DDC）。
数字下变频通常是一个单独的芯片电路或者FPGA的IP核，它是SDR系统的关键部分。
01数字下变频（DDC）一个常规的DDC包含三个主要部分：•一个数字混频器；•一个数字本振；•一个FIR低通滤波器。

SDR#用户手册说明书
A USER’S GUIDE TO SDR# (SDRSHARP)SDR# (aka “SDRSharp”) is an easy-to-use yet small and fast Software Defined Radio application for Windows created by Youssef Touil with collaborative assistance from other talented software engineers. SDR# is written in C#, a modern, general-purpose, object-oriented programming language developed by Microsoft.SDR# is intended as a Digital Signal Processing application for use with a wide range of RF hardware, including:•SoftRock•FiFiSDR•FUNcube Dongle•SDR-4•LazyDog’s LD-1•SDR-IQ•SDR-14•RTL2832U / RTLSDR•Any sound card based SDR front end•Any ExtIO based SDR front endMore radios will be supported as interest demands. Latest information can always be found at the SDR# website: / and on the #SDR channel on IRC, or via the mail reflector:/group/SDRSharp/The SDR# human interface is intuitive and flexible to use. “Run” and “Stop” buttons are found the very top of the screen, along with the ability to select live data from a connected IQ stream or playback of stored files.The balance of the SDR# screen consists of three functional areas:-Expandable control panels along the left-hand side-Tuning controls and spectrum display at the top-right-Waterfall display at bottom-right-Controls for spectrum Zoom and waterfall Contrast along the rightmost edgeEXPANDABLE CONTROL PANELSSDR# comes with four standard control panels:o Radioo Audioo AGCo FFT DisplayEach panel can be minimized by clicking on the “-“ sign, or expanded by clicking on the “+” sign. RADIO:The Radio panel includes information needed to configure, control, and tune the Software Defined Radio. Here is a brief description of functions that are available:1. MODE Selections include Narrow FM (NFM), AM, Lower Sideband (LSB), Upper Sideband (USB), Wide FM (WFM), Double Sideband (DSB), and CW with lower or upper-side offset (CW-L and CW-U) NFM is used for all FM modes except FM broadcast, which is WFM.2. FREQUENCYThis box shows the frequency that is actually being received. Direct entry is possible, but must be within range of the center frequency that is presently set. Click the mouse anywhere in the spectrum display to tune to that frequency.3. CENTERThis box shows the center frequency that the RF front-end is tuned to. The combination of FREQUENCY and CENTER displays can be used to tune SDR#. Once the CENTER frequency is set, any signal within the spectrum display can be tuned, based on the sample rate of the RF front end. See “Spectrum Display” for information on tuning using the mouse, otherwise center frequency (in Hz) can be entered directly.4. FRONT ENDVarious RF hardware options can be selected by clicking the down-arrow just to the right of the FRONT END button. Available devices can be selected via the pull-down menu, and applicable defaults will be displayed.The FRONT END button brings up a menu containing any configuration options that are available for the selected device.5. FILTER TYPE, FILTER BANDWIDTH, FILTER ORDERThese three options allow customization of the window function, bandwidth, and order of the DSP filter used by SDR#. Default options are chosen for nominal operation in each model, but can be changed as desired, and the specified bandwidth will be shown as a highlighted area on the spectrum display. Filter settings will return to the default values when SDR# is restarted.6. SQUELCHClicking the box enables the Squelch function, which mutes the audio output until the received signal exceeds the threshold value that is determined by the value in the box below. Lower values “loosen” the squelch or decrease the signal level needed for audio to be heard. Higher values require stronger signals before audio is heard. Squelch is available in AM and NFM modes only.7. CW SHIFTThis value determines the offset between transmit and receive frequencies in the CW modes for devices having transmit capability.8. SNAP TO GRID, STEP SIZEThese functions help to simplify tuning for channelized operation, and to customize the tuning response of SDR# for all modes. A wide range of step size options can be selected from the pull-down menu to accommodate various needs. For example, 12.5 kHz steps are used in aircraft communications, whereas single sideband requires tuning in increments of 100 Hz or less. The Snap-to-Grid option forces the tuned frequency to the nearest step size increment.9. CORRECT IQSDR# has an original algorithm that compensates gain and phase imbalances between the IQ channels. Without this compensation strong signals are mirrored with respect to the center of the spectrum, as can be seen in the spectrum display of other SDR programs. This unique feature of SDR# should be left on unless there is a reason to disable it.10. Swap I and QMost RF front ends will present I and Q signals in the proper way, but if not, click this box to swap them without changing hardware connections.11.FM StereoWhen selected, stereo output is available in WFM mode (for broadcast FM listening)12.Mark PeaksClicking this box toggles a visual indicator of peaks in the spectrum display as an aid for tuning.USING THE SPECTRUM DISPLAYThe above settings should enable basic SDR# Radio operation using RTL-SDR / RTL2832 USB DVB-T dongle. Default frequency and mode settings are for FM broadcast where signals are strong and something should be heard even with a limited antenna.QUICK START: Select the Front End, Enter a Center Frequency and Mode, then click “Start”. Default settings should be sufficient for normal listening.ANTENNA: The short antenna supplied with DVB-T dongles provides poor reception and should be replaced with a good VHF-UHF antenna mounted outdoors if possible. Low-loss RG-6/U coax is readily available at reasonable price. Adapters can be purchased to adapt the “F” connector used on RG-6/U to the PAL connector used on the dongle. Alternatively the supplied cable can be cut near the end and used to make an adapter patch cable. Details for making inexpensive wideband VHF/UHF antennas such asthe discone can be found online. Old TV or scanner antennas, “rabbit ears”, etc can also be used.SPECTRUM DISPLAYThe spectrum display shows a continuous display of the RF spectrum. The amount of spectrum displayed is a function of three factors:1.The Sample Rate of the RF Front end. This determines the amount of RF spectrum that isdigitized and sent to SDR# for digital processing.2.The setting chosen in the “FFT Display” control panel.3.The setting of the “Zoom” slider to the right of the display area. Fully down, the amount ofspectrum displayed is the full amount that is provided by the RF Front End. As the slider ismoved up, the display zooms-in on the frequency presently tuned, showing more detail of thesignal being received, but less of the overall spectrum.The relative amplitude of each signal can be estimated by comparing the height of each peak. With practice one can quickly identify the different modulation types, based on their appearance in the spectrum display.Ability to easily tailor the spectrum display adds a great deal of capability to SDR#.The FFT setting determines the base resolution of the spectrum display. A fairly low FFT setting (such as 4096) provides adequate resolution for many purposes yet places a minimal burden on the CPU. Increasing the FFT provides much greater resolution, but at the cost of increasing the load on the PC CPU, with the highest settings requiring so much computational time that audio becomes choppy. The general rule of thumb is to use as high a setting as needed for your purposes, but no more.The zoom feature makes it easy to temporarily see more details without changing the base resolution. It is analogous to an old-time newspaper photo, where a magnifying glass enables you to see the dots that are always present in the image. Zooming-in on a signal makes it easier to tune to the exact center, and to view a limited chunk of spectrum in more detail.The mouse can be used to change the center frequency by clicking and dragging the background of the spectrum display to the right or left. Clicking on any part of the display area will tune SDR# to that frequency.OTHER EXPANDABLE CONTROL PANELSAUDIO:The Audio control panel allows control of the volume and selection of the audio source and destination. For most users the default choices will be OK. Those who need a source of unfiltered audio should unclick the “Filter Audio” box. For users who feed the output of SDR# to a digital decoding program of some sort, the Audio Output should be changed to Virtual Audio Cable or whatever alternative is used for this purpose.AGC:This panel provides control over the Automatic Gain Control feature of SDR#. Default settings should be OK for most users.FFT Display:Other than changing the resolution of the FFT as explained above, default settings should be OK for most users.CUSTOM:Developers are working on new features that add new functionality to SDR#, resulting in the addition of new expandable control panels for these features. If you have a version of SDR# that includes custom control panels, you will need to look to the SDR# website and discussion groups for further information. Some examples include:AUTO TUNER – automatically tunes to peak signals much like a scanner, including loggingfrequencies and other enhancements.TRUNKING – extracting control channel information from a 2nd dongle using Unitrunker toautomatically follow trunked radio systemThis ability to enhance SDR# will continue to evolve as the potential of software defined radio is explored and new applications created.WATERFALL DISPLAYThe waterfall display is a time-varying spectral display, and brings an exciting new dimension to radio listening. Previously used in applications such as sonar, speech processing, and seismology, the waterfall (also known as “spectrogram”) display gives us a brief look back in time as signals appear at the top, and then scroll down and off the bottom of the display. The frequency of each signal is the same as in the spectrum display above, so the waterfall will show “wiggles” as we click and drag the spectrum display to change frequency. Since the waterfall is a 2 dimensional view (frequency vs. time), amplitude information is displayed through the horizontal width and color of the line in the waterfall rather than through the peaks.A slider control allows customization of the display “Contrast”, but the default setting should be OK for most users. Black indicates no signal, and shades of blue, yellow and red correspond to increasingly higher received signal levels. A very strong signal will be almost solid red, while a weak signal will consist of mostly yellow and blue. Modulation type can be determined from the waterfall display as well, in fact the “dits and dahs” of a CW (Morse) signal can usually be read vertically as the display scrolls. Since the display color contrast is relative, the user can vary it to suit specific needs.The Zoom control affects the waterfall display in the same way as the spectrum display.FOR MORE INFORMATION:1.the official SDR# website: /2.shortcut to official download page: /index.php/downloadsNote: “Continuous Integration” or “nightly” versions contain latest enhancements and features3.RTL2832 DVB-T dongle installation information: /softwarewindowsNOTE: THE ABOVE PROCEDURE MUST BE FOLLOWED BEFORE RTL DEVICES CAN BE USED WITH SDR#!4.Bob Rich’s standing download site for the lastest version of his experimental code (AutoTuner, Trunking, etc):https:///Release-latest.zip5.#rtlsdr and #sdrsharp on Freenode IRC6.Yahoo group: /group/SDRSharp/ABOUT THIS DOCUMENT:Copyright (C)2012 Robert A.

Now itʼs time to consider how you can maximize the fun and excitement your equipment offers. VocoPro and the Electronic Industries Associationʼs Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing.Sound can be deceiving. Over time your hearing “comfort level” adapts to a higher volume of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.To establish a safe level:• Start your volume control at a low setting.• Slowly increase the sound until you can hear it comfortably and clearly, and withoutdistortion.Once you have established a comfortable sound level:• Set the dial and leave it there.• Pay attention to the different levels in various recordings.Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Associationʼs Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise.

FiFi-SDR软件定义无线电说明书
Projekt ExtIO_FiFi.dll Wenn dein FiFi denkt er sei ein RadioJetkönnte man dann auch die Vorzüge nutzen, die die RadioJet-Software bietet?Peter Walter (Bonito)Nun, wie nicht jeder weiß, bin ich jemand der 1. Stunde, der schon 1972 die ersten Software-Programme für Funkamateure geschrieben hat. Und so bin ich auch der, der heute mit bedauern feststellt, das es nur wenige gibt, die etwas vom Radio und Computer verstehen oder wissen wollen. Und so schrieb ich wieder einmal etwas Software für die …armen Jungs“ und stellte es aus Werbegründen kostenlos zur Verfügung.Für das softwaredefinierte Radio FiFi-SDR (siehe Funkamateur 11/10) wird von mir hier eine FiFi-Software vorgesellt, die ursprünglich aus dem Open Source Project vom RadioJet (Funkamateur 7/12) stammt. Eins der dort verwendeten Programmierbeispiele ist ganz speziell für den Einsatzmit dem FiFi-SDR kostenlos bereitgestellt worden.Fast jeder Radioamateur versteht ein SDR als eine kleine Büchse, mit dem man Radiosendungen empfangen kann. Doch das, was ein SDR wirklich aus-macht, ist nicht die kleine Büchse, Nein,- das ist die Software. Denn korrekt wäre die kleine Büchse nur ein IQ-Empfänger, denn ein komplettes softwaredefiniertes Radio besteht technisch gesehen aus vier verschiedenen Dingen: 1. Empfang ADC2. Demodulation Software3. Wiedergabe DAC4. Kontroll-Einheit RemoteFür den 1. Punkt nutzen wir die kleine Büchse, wo FiFi-SDR draufsteht, aber einIQ-Empfänger drin ist. Und für die ande-ren Punkte muss der Computer herhalten.Für den 2. Punkt brauchen wir ein Pro-gramm, wie das hier besprochene. Für den 3. Punkt wird die Soundkarte des Computers genutzt. Und für den 4. Punkt braucht man wie-derum eine Software, die die Hardware des IQ-Empfängers einstellt und steuert.Somit steht fest: Mit der Software steht und fällt jedes SDR. Das kann man be-sonders gut am RadioJet feststellen, den der führt gerade die Liste der besten SDR’s an, obwohl ich (der Entwickler) glaube, dass andere SDR’s technisch ge-sehen eine größeres Potential hätten, wenn man der Software nur etwas mehr Beachtung geschenkt hätte.Aber offensichtlich versteht das nicht jeder Hersteller, besonders wenn auf die frei im Internet verfügbare Software hin-gewiesen wird. Wobei es dann erst richtig zum SDR-Abenteuer wird und mancher zaghafte Versuch eines Anfängers in ir-gendeiner Schublade endet. Schuld an dieser Miesere ist der User selbst, denn Software hat keinen Wert in der Welt der Funk- und Radio-Amateure, weil sie immer kostenlos im Internet zu haben ist,- und sei sie auch geklaut. Daher gibt es nur wenig Vielfalt, weil alles Erreichbare letztendlich nur beim Winrad oder Clone endet und daher wird kein SDR sehr viel besser sein, wie alle Anderen auch. Ich behaupte also, das die Mittelmäßig-keit der üblichen Software schuld daran ist, wo in der Liste der beliebtesten SDR’s ein IQ-Empfänger letztendlich steht. Nun besaß ich die Freiheit, diese Behauptung unter Beweis zustellen und degradierte alle möglichen IQ-Empfänger zum ‚billigen‘ Panorama-Empfänger fürmein RadioJet, weil doch eigentlich zum perfekten Radio auch ein möglichst brei-tes Übersichts-Spektrum gehört. So aber stellte sich von allein heraus, dass die Billigsten unter den SDR’s be-sonders gut dafür geeignet waren, weil doch der Empfang selbst, von RadioJeterledigt wird, der nicht so unter den Nachteilen leidet, wie es unvermeidlichbreitbandige SDR’s so mit sich bringen.Da die vom RadioJet genutzten ‚Panora-ma-Empfänger’ völlig selbstständig ar-beiten müssen, wurde es notwendig sich mit den von mir so ungeliebten ExtIQ-DLL’s zu befassen, weil man mir deren Nutzung jederzeit kommerziell untersa-gen könnte. So machte ich mich daran dieDinger selbst zu programmieren.Panorama-Spectroscopeein typisches DRM-Signal wird hier gerade demoduliert rechts unten sehen Sie die decodierten Stations- Daten und Meldungen der heller Bereich ist die Kennzeichnung für die 12 kHz Filter-Breite ein typisches Amplituden-Signal (AM-Station) der heller Bereich ist die 12 kHz Filter-Breite! vielleicht findet sich jemand, der das hier Übersetzt !■ woher bekommt man das Alles was aus dem Internet geladen wird, das wird am Ende dieses Beitrags als Weblink (URLs ) besonders aufgelistet.■die ExtIO_DLLDie ExtIO_DLL wird in der Regel für die Winrad-Software oder Clones gebraucht.Für viele IQ-Empfänger ist solche DLL verfügbar, aber kaum Spezielleres, um die Leistung voll nutzen zu können.So sah ich mich gezwungen spezielle DLL’s zu programmieren damit es für die eigene Software komfortabler zugeht. Ich erstellte als Programmierbeispiel eine für RadioJet und eine für Excalibur. Später kam noch eine ExtIO_FiFi.dll hinzu, weil mir ein Softrock-Treiber Probleme berei-tet, obwohl er gar nicht gebraucht wurde. Alle drei DLL’s sind frei auf dem Open Source Projekt vom RadioJet verfügbar, damit kann sich jeder seine eigene Soft-ware erstellen und es sich ansehen wie es funktioniert, ohne von daher gleich zum Software Pirat zu avancieren.So wurde nun auch ausprobiert, welcher IQ-Empfänger sich für RadioJet als Pano-rama-Empfänger eignet. Dafür testete ich FiFi-SDR, Pappradio, FDM-S1, Perseus, Excalibur, PMSDR, SDR-14/IQ, usw.. Und so stellte ich auch bald fest, dassunter Berücksichtigung von Preis, Leis-tung und OpenSource der FiFi-SDR derbeste Kandidat war, womit ich beweisen kann, das die Software den Freizeitwert jedes SDR’s um ein vielfaches steigert. ■das Open Source Project Ganz besonders kommt das den Bastlernzu gute, die sich jetzt vielleicht einmalam Programmieren ausprobieren möch-ten. Denn nichts ist hilfreicher, als einausprobiertes, funktionierendes Projekt.Das Projekt finden Sie auf den RadioJet Webseiten unter RJ10FiFi, das mit einem Microsoft Visual-C Compiler (V.6) er-stellt wurde. Es ist also besonders daraufausgelegt, das Programmieren zu lernen ohne gleich mit der Radio-Hardcore kon-frontiert zu werden. Für die Linux- oder Borland-Experten kann ich nur hoffen, das irgendjemand dieses Projekt so um-wandelt das es auch Experten verstehen. ■die Anwender-Software Die Software wird als .ZIP vom Internet geladen, entpackt und das RJ10FiFi.exe gestartet. Es sollten aber alle FiFi-Treiber vorher installiert sein. RJ10FiFi regist-riert nichts und kann daher statt UnInstall einfach nur gelöscht werden. Die Software ist kostenlos und somit freinach dem Motto, no Service, no Support und keine Garantie! Die Software lässt naturgemäß einiges offen, dennoch bietet sie mehr als die übliche Software. Zum Beispiel ist auch gleich DRM integriert. Dennoch war das Ganze immer nur dafürgedacht, unter Beweis zu stellen, dass gute Software nur den Freizeitwert einesIQ-Empfängers verbessert, nicht aberseine elektrischen Eigenschaften. ■das besondere Sound Device Wäre die Hardware so entworfen, wie beim RadioJet, dann könnte FiFi wie ein Radiojet arbeiten. Denn beide Empfänger haben ein eigenes Sound (Input) Device. Beim FiFi wird im 24kHz Hauptspektrum ein Real-Signal empfangen, das vomADC des Input Device mit 48k Sampleabgefragt und zur Audio-Demodulation weitergereicht wird. Gleichzeitig wird aber auch noch ein Complex-Signal emp-fangen, wobei dieselbe Soundkarte nun mit 98 bzw. 192 kHz abfragt wird, um das dann unten auf einem ebenso breitenPanorama-Spectroscope anzubieten.Das Besondere daran ist aber, dass beide Signale dieselbe Soundkarte und Signal-Quelle nutzen, die gehandhabt wird, als seien es zwei verschiedene Soundkarten.Bild 3: Ein DRM Signal wird gerade demoduliert, die Stations-Info wird ausgewertet und auch jede neue Meldung wird decodiert1ÜbersichtfensterZentrums-Markierung2 Panorama3 ExtIO-Dialogrot ist das Real-Signalweiß ist das IQ-Complex-Signalbeim Einsatz einer fremden Soundkarte■ die Si570-KalibrierungIm Bild 3 sehen Sie wo der ExtIO-Dialog aufgerufen wird. Dort wird die Frequenz kalibriert und das dBm-Offset des Signal-pegels. Die Abweichung der Grundein-stellung des Si570-Oszillators wird mit Xtal.Correcture bestimmt. Dieser Wert wird üblicher Weise mit einem AM-Sender unterhalb 1 MHz bestimmt z.B. 177 kHz Deutschlandradio. Der wird also solange eingestellt, bis im Spektrum der lange Trägerbalken des AM-Signals ge-nau auf der Zentrums-Markierung steht. In der Vergangenheit lag im Hauptfenster die Frequenz um ca. 12 kHz daneben und so hat mancher User hier -600 eintragen müssen. Ich hatte übersehen, dass ein SDR die Frequenz immer von links sieht und RadioJet immer aus der Mitte. Das ist aber am 25. Feb. 2013 korrigiert wor-den. Also hier nicht mehr -600 eintragen. Xtal.Scaling ist die Abweichung, die sich gleichmäßig von 1 Hz bis 30 MHz ganz allmählich verzieht. Suchen Sie sich ei-nen AM-Sender >15 MHz und kalibrie-ren ihn wie eben beschrieben. Diese Me-thode der Kalibrierung ist meist besser, als der Einsatz teurer Messgeräten. Vor allem ist es auf jedem Fieldday ohne Handbuch durchführbar.■das S-Meter kalibrierenDas S-Meter beim FiFi wird niemals ge-nau sein, daher ist es vorgesehen es im ExtIO-Dialog zu kalibrieren. Ein guter Wert für dBm Level Offset liegt auf -22, wobei mir RadioJet als Referenz diente. Ganz links unter dem S-Meter befindetsich ein Knopf mit dem zwischen vierverschiedenen Anzeigen gewählt wird.■das IQ-DC-Problem Das Zentrum der Demodulation wurde von mir um 12 kHz nach rechts versetzt, weil ich damit minderer Soundkarten-Qualität und deren Kalibrierung aus dem Wege gehe. Denn es ist die Mühe nicht Wert, wenn ich sowieso oben im 24 kHz Spektrum ein Realsignal verarbeite und unten aus pädagogischen Gründen dieIQ-Complex-Probleme sichtbar lasse.■ Anleitung zur BedienungEine RadioJet Anleitung finden Sie im-mer im Internet, wenn Sie sie auch noch lesen dann sind Sie klar im Vorteil. Trotzdem wird es immer ohne vorheriges lesen bedient. Warum auch? Learning by doing, das ist immer noch die beste Methode mit der die meisten Radio-Amateure relativ schnell klar kommen. Bei Bonito ist einiges so komplett anders, dass, wenn es zufällig entdeckt wurde, mancher so davon entzückt ist, dass er die Art und Weise übernimmt und dann immer häufiger neue Bedienungsweisen entdeckt. Man zeigt dann später gar kein Verständnis mehr dafür, wenn es in ande-ren Programmen nicht auch so geht.■ die Regeln der BedienungAlles in der Anwendung ist grundsätzlichso gestaltet, dass man es mit der Hand auf der Maus erreichen und bedienen kann. Man klickt mit der rechten oder linken Maustaste, besonders viel scrollt man mit dem Mausrad. Ganz besonders das ‚Schlittern’ (Slide) und ‚Scrollen’ in den Spektren findet großen Zuspruch beim Anwender. Slide: Die rechte Maustaste im Spektrum drücken und dann bei ge-haltener Taste die Maus hin und her schieben. Sie werden sich wundern wie schnell und leicht man ganze Frequenz-bänder durchscrollt. Einfaches Doppel-klicken z.B. auf eine AM-Station bringt die Station auf die Zentrums-Markierung. Potis werden grundsätzlich nur mit dem Mausrad bedient und ein Doppelklick bring das Poti in die Werkseinstellung(default). Scroll: Sie halten nur die Mausüber das Poti und rollen dann das Rad der Maus hin und her. Wenn Sie noch zusätz-lich die Strg-Taste drücken, dann wird in kleinsten, feinsten Schritten das Poti ver-stellt, das ist manchmal auch sehr träge. ■die Frequenz Anzeige Auf den Ziffern der Frequenz-Anzeige kann man klicken und scrollen. So wirdjeder beliebige Bandbereich angewählt. Die Memory- Buttons M1-M2 sind Spei-cher-Tasten, mit denen schnell eine be-liebte Frequenz einstellt wird. Ihre eigene Frequenz speichern Sie, indem Sie mit der rechten Maustaste auf einen der ge-wünschten Memory- Button klicken. ■ manuelle Frequenz-Eingabejede Zahl die sie einfach in Taste tippen wird im Eingabefeld unter dem Zahlen-blocks landen. Jedes () Return oder auch Enter stellt die Frequenz sofort ein. Es gilt die Regel:Komma-Zahlen <32.0 werden als MHz verstanden und Zahlen >32.0 als kHz. Also: 147.3 = 143 000 Hz 6.095 = 6 095 000 Hz 177 = 177000 Hz 20 = 20 000 000 Hz■ der ZF-RekorderDas Signal kann aufgezeichnet und wie-dergegeben werden. Es werden immer beide Signale aufgezeichnet. Also das IQ-Complex und das Real-Signal, die sich nur im Filenamen mit IF oder IQ unterscheiden. Das IF steht immer für eine 48k Real-Signal und das IQ hat die Samplerate, die Sie gewählt hatten ein-schließlich Datum, Mode und Frequenz.■ und was noch fehltedas wäre ein FiFi-SDR 2.0Wie bereits erwähnt ist das wesendliche Merkmal eines guten SDR’s seine Soft-ware und daher ist nun das FiFi-SDR in der Liste der beliebtesten SDR’s schon einige Stufen höher gerutscht, weil das Bonito-Programm weit aus weniger Prob-leme macht und mehr bietet, als so man-ches andere kostenlose Programme. Um aber in der Oberliga mitzuspielen zu können, müssten nur geringfügige Ände-rungen vorgenommen werden. Das sind Dinge, die dann von der Software gesteu-ert werden können z.B. eine ATT und einen Vorverstärker der dann wie beim RadioJet eine Kaskadierung bis 144 dBm ermöglicht. Würde man den FiFi auch noch mit der RadioJet Software betrei-ben, dann würde es schon etwas mehr kosten. Ich denke das werden letztendlich dann mindestens 400 Euro sein.Natürlich hätte ich noch einiges zu sagen, aber das mache ich auf meinen eigenen Seiten im Internet, dort kann ich dann auch die Dinge beim Namen nennen. Hier habe ich das bewusst unterlassen.Also, bis zum nächsten mal.Peter Walter (Bonito)Anwender-Software/manuals/radiojet/opensource/PG_RJ10FiFi.zipExtIO_FiFi.dll/manuals/radiojet/opensource/ExtIO_FiFi.zipOpenSource RJ10FiFi\manuals\radiojet\opensource■die URLs。

Getting Started with RTL-SDR and SDR-Sharp and CubicSDRCreated by lady adahttps:///getting-started-with-rtl-sdr-and-sdr-sharpLast updated on 2023-08-29 02:32:35 PM EDT34581214161922Table of ContentsOverviewSDR-Sharp for Windows• Download & Install SoftwareDriver Fix SDR# FM RadioSDR# NWR (Weather) Radio• Going forwardCubicSDR for mac os• Download & Install Software • Start the SDR DeviceCubicSDR FM Radio• Signal Type• Center FrequencyCubicSDR NWR (Weather) Radio• Going forwardF.A.Q.OverviewSoftware-defined radio (SDR) is a technique for turning a computer into a radio. But not just an AM/FM radio - by using the computing power on your desktop you can listen and decode a wide variety of broadcasts. SDR can turn your computer into a weather-band receiver, a police/fire report scanner, a music listening station, and more! Instead of manually tuning inductors, its all done in software by chips fast enough to pick up and decode radio waves on the flyIf you've ever been curious about software defined radio (SDR), this USB stick is the easiest way possible to have fun with a powerful, configurable receiver. Packed with the powerful RTL2832U and R820T tuner, it can tune into signals from 24MHz to 1850MHz. That means you can use a computer (with Windows, Mac, or Linux) to tune into: FM Radio, AM signals (but not AM radio), CW (morse code!), unencrypted radio signals (such as those used by many police and fire departments), POCSAG pagers, and more.In this tutorial we'll show how to get your very first listening adventure underway -listening to FM radio and decoding the RDS/RBDS data signal that is sent along with many FM radio stations as well.Want lots more info? There's hundreds of tutorials, posts and projects over at /Next, we'll set up the software -- if you're using windows, head to the next page -- SD R-Sharp for Windows (). On mac os, jump to the page CubicSDR for mac os ().To see some SDR action live, check out this episode of John Park's Workshop: SDR-Sharp for WindowsDownload & Install SoftwareWe'll be using the awesome SDR# software for windows, which is really easy to use and very powerful as well! Visit https:///download to download () - we're using Rev 1243If for some reason the site is down, we have a mirror of the install folder from5/19/2014 ()We suggest downloading the latest version as there will be minor bug fixes, etc!Save and uncompress the zip file Double-click on install-rtlsdr.batDouble-click on SDRSharp.exeDriver FixBefore we continue, we'll have to install the Windows driver for the RTL USB stick and then swap it for a 'low level access' driver. The default driver assumes you'll just be using the RTL-SDR for watching TV or radio but we want to be able to control it to do much more.Plug in the stick, Windows should automatically install the REALTEK 2832U driverNow from inside the SDR# directory, run Zadig which will do the driver swapping for us.Here's a version 2.2 exe if you need it:zadig_2.2.zipFrom the Options menu, select List All DevicesThen from the devices drop-down, find one that says Bulk-In, Interface (interface 0). If there's more then one, select one at a time, and verify below to get the right one. Check that you get USB ID 0x0BDA (vid) and 0x2838 (pid) and the RTL2832UUSB driverMake sure to the right of the green arrow you see WinUSBClick Replace DriverThat's it!SDR# FM RadioLets start by just listening to every-day FM radio. Open up SDRsharp.exe (you can close Zadig)Begin by selecting the RTL-USB dongle instead of audio cardSelect WFM (wide-band FM radio) under the Radio signal typeClick on ConfigureAnd set the gain about half-way upYou can set your favorite frequency (FM station) by clicking on the large numbers up topClick Play/Start and set the volume starting from low to high so you don't hurt yourears!You can 'seek' for radio stations by looking for peaks. Click on them to tune inWith the latest versions of SDR-Sharp it will automatically detect and decode RBDS/RDS data that is sent along with FM radioChances are your radio station is also playing Donna Summer!SDR# NWR (Weather) RadioMost every-day AM/FM radios can't tune into theNOAA Weather Radio (NWR) All Hazards network but with RTL-SDR we can! NWR is the national weather alert system, which broadcasts weather data as well as emergency alerts. ()Let's tune into the closest weather station to Adafruit Southern California, which is in Los Angeles. You'll want to tune into whatever station is closest to you.To begin, visit the NOAA weather station frequencies-by-county index here ()The frequency is 162.550 MHz, type that into the SDR# frequency windowYou can see a little peak, its much smaller signal than the FM radio stations. It's also much thinner which makes it a narrow-band FM rather than wideband. Since its voice, not stereo music, they use less of the frequency band, so select NFM as the decoding typeThe station is marked as degraded, but by amplifying the gain on the RTL-SDR we were able to tune inYou should be able to hear a computer-generated voice speaking out the weather forcast. It's not terribly exciting but it is very thorough, often giving very detailed reports. The signal continuously transmits so you can tune in at any time! Going forwardnow that you have some basic functionality working, try tuning into other frequencies, and trying the different kind of decoding (e.g. CW/AM/NFM) to tune into AM radio! CubicSDR for mac osDownload & Install SoftwareOn mac os, we'll be using the excellent CubicSDR () cross-platform, open source software. For this tutorial we'll use release version 0.2.3 Head to the Downloads () page to grab the latest version, or click this link to directly download 0.2.3Download CubicSDR 0.2.3Once you've downloaded the installer (in this case named CubicSDR-0.2.3-Darwin.dmg), double-click it to mount the disk image, and then drag the CubicSDR.ap p to your Applications folder as shown here.Now, plug your RTL-SDR dongle into a USB port on your mac, and then double-click the CubicSDR.app in your Applications folder to run it.Start the SDR DeviceWhen you launch CubicSDR, it will pop up a window asking you to select and startyour SDR device. Pick the one named Generic RTL2832U OEM :: 00000001 and thenclick Start.CubicSDR FM RadioWe'll begin by listening to some broadcast FM radio.First, make sure your RTL device has started by clicking the File > Stop / Device menu item. When it is running you will see the waterfall frequency display moving at the bottom of the interface, as well as some moving waveforms in the other areas. Array Signal TypeThe CubicSDR software in combination with the RTL dongle can tune and demodulatedifferent ranges and types of radio signals. For this example, we'll select FrequencyModulation Stereo (FMS) as the signal type.Center FrequencyNext, you can tune in a station! Start by setting a center frequency for a station you like, by clicking on the numbers under the "Center Frequency" heading. ArrayThis will bring a range of frequencies into view -- approximately 3MHz at a time areavailable. Now, you can set a demodulator down on a range you want to tune. This isdone by clicking in the waterfall display, with the cursor at the center of thefrequencies you want to hear. This will usually be the orange and red display section, showing you where the strongest signal lies.Here, the demodulator has been set at 91.499261MHz, and we have a nice strong signal. Music plays! ArrayYou can see the fine tuning section in the upper left corner gives us a zoomed in view of the demodulator. You can drag this one left and right in the waterfall section to finetune, or grab one of the outer edges of the demodulator to change the bandwidththat is being processed. Too wide and you'll pick up unwanted signals, too narrowand you'll start to cut off important parts of the signal.You can search for other stations by scrubbing the peaks display left or right andlooking for strong peaks. Set down a demodulator in the waterfall area under a strong peak to listen in.The frequency band for FM broadcast radio is 88MHz to 108MHz.CubicSDR NWR (Weather) RadioMost every-day AM/FM radios can't tune into theNOAA Weather Radio (NWR) All Hazards network but with RTL-SDR we can!NWR is the national weather alert system,which broadcasts weather data as well as emergency alerts. ()Let's tune into the closest weather station to Adafruit Southern California, which is in Los Angeles. You'll want to tune into whatever station is closest to you.To begin, visit the NOAA weather station frequencies-by-county index here ()The frequency is 162.550 MHz, type that into the CubicSDR tuner window by hoveringover the Center Frequency box and hitting spacebar.You can see a little peak, its much smaller signal than the FM radio stations. It's also much thinner which makes it a narrow-band FM rather than wideband. Since it's voice, not stereo music, they use less of the frequency band, so select NFM as the decoding type.Click to set a demodulator at the 162.550 MHz peak. ArrayYou should be able to hear a computer-generated voice speaking out the weatherforecast. It's not terribly exciting but it is very thorough, often giving very detailedreports. The signal continuously transmits so you can tune in at any time!Going forwardNow that you have some basic functionality working, try tuning into other frequencies, and trying the different kind of decoding (e.g. CW/AM/NFM) to tune into AM radio! F.A.Q.The SDR dongle seems to get hot!Yep, these run pretty warm. As long as it's still working, you should be good to go. There's a pretty advanced chipset inside which can consume a lot of power What kind of computer do I need?You need a computer with at least one USB 2.0 or higher port. You will also need admin privs to install the software, we used it on Windows 7, XP should be the same. There's also software for Mac and Linux but we don't have tutorials for it.
