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.

Science FairINSTRUCTION MANUAL PRICE: 50 ₵ELECTRONIC PROJECT KIT #28-110THREE TRANSISTOR SHORT WAVE RADIOThe air is literally full of radio signals from practically every country in the world. These “short wave” signals are propagated through space and refracted back to earth by the ionosphere to points many miles from the transmitter source. As a result, communications services, international broadcasters, radio amateurs, and others depend on this “refraction” and return to earth of short wave signals for long distance communications around the globe. Still, it is difficult to believe that you will be receiving signals from far off places with only a three transistor radio. A regenerative high gain detector with two stages of equally high gain audio amplification provides enough audio drive for either a crystal earphone or any audio power amplifier.

Do one step at a time and then check off the step in the box provided. Before beginning, read over the enclosed page labeled “Construction Hints”.The step by step instructions indicate a soldering requirement; however, these connections can be made by firmly twisting joining wires together. If the connection is secure the circuit will work for temporary or testing purposes. If you wish a more permanent circuit, it is always best to secure these connections by soldering. Before soldering, read the instructions in “Construction Hints”.1. ( ) Check the parts list to see that everything listed is included. Check each step as you progress ( ).2. ( ) Place the pictorial diagram near the perfboard chassis so that the pictorial can be used as a guide for exact placement of parts. The gray lines in the pictorial diagram indicate components and wires which are mounted under the circuit board. The solid lines indicate components and wires mounted on top of the circuit board.3. ( ) Slightly enlarge the perfboard holes so that terminal strips T1 through T4 fit snugly in the perfboard as shown in Fig. 1 so that they face toward the back of the radio.4. ( ) Slightly enlarge the holes for the tuning control bracket to accommodate the 4-40 X 3/8” screws. Mount the tuning control bracket as shown in the pictorialdiagram Fig 1 using the two screws and two 4-40 nuts.Mount the 140pF variable capacitor C5 as shown below using the short black screws. Thread the shaft extension on the variable capacitor and tighten.5. ( ) Mount potentiometer R2 orientating the lugs as shown in the pictorial diagram Fig 1.

( ) Install the small knobs on potentiometers R2 and R7 and tighten the set screws until the knobs hold firmly to the potentiometer shaft. Install the large knob on the tuning capacitor C5 and tighten the set screw until the knob holds firmly to the tuning capacitor shaft. Do not overtighten the set screws.50. ( ) Remove ¼” of insulation from both ends of a 16-1/2” piece of wire. Holding the wire as shown in the drawing below, wrap it aroun d a “AA” battery for 8 full turns. Leave at least ¼” left over for lead length.The completed coil should look like the coil in the drawing. Wrap the coil with clear tape to prevent it from springing apart. Mount the coil (L1) by inserting one end into terminal strip T3 and the other end into terminal strip T4. Tighten the terminal strip screws until the coil leads are firmly held in place.You have completed all connections, both wiring and soldering. Carefully double check the work against the pictorial diagram.OPERATIONSThis radio will work with a 10’ or 20’ piece of wire strung across the floor used as an antenna. However, for top efficiency you will need a good antenna and ground connection. Your radio reception will never be any better than your antenna system. You may use a cold water pipe for ground; however, a metal rod driven 2’ or 4’ into the ground works best. Excellent for this use is the Radio Shack ground rod (Radio Shack Cat. #15-530). Connect the wire from the ground rod to the Antenna Ground terminal of terminal strip T2. The Antenna terminal of terminal strip T2 should be connected to an outdoor antenna of the type illustrated in figure 3 (Radio Shack Cat. #278-1373), and can be as long as facilities permit. The longer the antenna you are able to construct, the better quantity of reception you will receive, especially at low frequency. If this is not practical, such makeshift antennas can be used as your television antenna, citizens band antenna, or even the metal dial stop of your telephone.Connect the read lead of the battery clip to the positive (+) terminal of the terminal strip T1 and the black lead to the negative (-) terminal of the terminal strip T1. Insert the earphone plug into the earphone jack J1. Insert a 9V transistor battery (Radio Shack Cat. #23-464 or 23-152) and you are ready to operate your radio.There are three controls on your short wave radio. The potentiometer R7 is the volume control for the audio output, the other potentiometer R2 is the regeneration control. The variable capacitor C5 is your tuning capacitor. To operate the radio, advance R7 fully clockwise, turn R2 half way clockwise. Now slowly tune the variable tuning capacitor until a station is heard. Adjust the potentiometer R2 until a maximum signal is heard. If the regeneration control R2 is advanced too far, a loud pop or squeal will be heard in the earphone. This indicated that you have gone into full regeneration and the potentiometer should be backed off slightly. It is possible to receive code (CW) in this condition. In order to hear a voice signal you need to adjust the regeneration control just prior to this oscillation condition. This point is referred to as the threshold point. If necessary reduce the volume to a comfortable listening level using the volume control R7, not the regeneration control.ADDITIONAL COIL WINDING INFORMATIONYour shortwave radio can be operated at frequencies ranging from 4.5 to about 50MHZ depending on the number of turns in the coil. A chart is given below which indicates the number of turns required for a given frequency of operation. Construct the coil as shown in the step by step instructions but with the number of turns required for the frequency desired. For the larger coils cellophane tape can be used to hold the coil together. Different frequencies or operations have better reception depending on the time of day. Included below is additional information which shows the best time to listen to the frequency that you are interested in.Frequency Coil Turns Best Reception Time 4.5-7 MHz 46 Late night6-10 MHz 25 Night often sunset9-14 MHz 15 Late afternoon-night13-20 MHz 8 Morning-afternoon19-28 MHz 5 Morning-early afternoon 26-50 MHz 2 MorningPOWER SUPPLYFor more permanent use you can completely eliminate the need for batteries with the AC-DC power supply kit #28-104. It supplies either 6 or 9 volts DC for most of the Science Fair Kits as well as most transistor radios, tape recorders, and phonographs. Complete connections are shown below.AMPLIFIER CONNECTIONSIf you wish to use a speaker with your radio it is necessary to use additional amplification. Ideal for the purpose is the Science Fair OTL Amplifier #28-106 and the Science Fair Extension Speaker #28-123. It is necessary to couple the radio to the amplifier with a dropping transformer #273-2378. The unit will probably work better in this condition if resistor R-11 is removed. Complete connections are shown below.OTL AUDIO AMPLIFIERSHORT WAVE RADIOFIG. 2 – SCHEMATIC。

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.

业余电台设备基本操作与调整

轻松学业余电台通信系列文章（4）业余电台设备基本操作与调整荣新华在上一期文章中，我们为初学短波通信的爱好者简要介绍了短波业余电台开台前的准备工作，包括操作证书考核、电台室基本布置和天线的架设施工与基本调试。

在本篇文章中，我们从一般的角度介绍收发信机、天线调谐器和功率/驻波比表等常见设备的基本操作与调整。

需要提请大家注意的是，对任何设备的操作与调整最好严格遵照说明书进行，否则操作的失误有可能会造成设备损坏。

如果手头没有说明书，大家可以参考本文中介绍的一般性原则。

由于设备种类多样，我们介绍的原则只能是针对一部分设备完全适用，对其它设备仅供参考。

收发信机操作收发信机（transceiver）俗称为电台，顾名思义，是将接收机和发射机合一的设备。

与普通的移动电话不同，用作业余电台的收发信机一般不能接收和发射同时工作，在缺省情况下，收发信机处于接收状态，可通过手按PTT键或用声控（VOX）的方式切换到发射状态。

收发信机的一般操作步骤如下：1. 开机前仔细检查设备连线是否正确，特别要检查天线有无妥善连接。

检查各旋钮的控制功能，应使其均处于适中位置。

2. 打开电源开关，选择工作频率，设置工作模式（对于SSB通信，一般小于9MHz为LSB，否则为USB）。

调整增益旋钮，使接收音量合适。

把控制发射功率的旋钮调小一些。

先转动调谐旋钮在工作频率附近收听一段时间，不要急于发射。

对于一些老式收发信机来说，这段收听时间是必要的预热过程，可确保工作频率稳定。

3. 开始的时候应使用较小发射功率，发现一切正常（功率指示会根据说话或发报摆动，驻波比处于安全范围）后方可在接收状态时调大功率。

如发现不正常，要及时停止发射，要对天线系统甚至对收发信机本身进行检查。

为了避免损坏设备，我们强烈建议大家不要在发射时对收发信机作任何调节。

4. 操作完毕要把各旋钮恢复到适中位置，关闭电源，拆去天线插头，并切断交流电源。

再次强调：不要在不接天线的情况下或者天线的驻波比很差的情况下发射。

【精品】短波收音机收听手册

短波收音机收听手册当下市面上的全波段（WorldBand）数调短波收音机调谐的频率跨度很大，典型的调谐范围从150KHz到30000KHz,几乎囊括长波、中波、短波的全部波段。

根据国际无线电联盟的协定，无线电频率被划分并供应给不同用途的使用者。

虽然偶有犯规者，但绝大多数台(站）都恪守许可使用的频率.150KHz及以下.这个频率的无线电波不能通过电离层传播，却可以很好地穿透海洋的深处，因此，在这个频率下可以发现许多做潜艇通讯的军事电台.德国、英国、日本、瑞士和白俄罗斯等国的标准时间标准频率发播台的发射频率都在20-80khz之间,普通收音机是根本接收不到的。

150到540KHz。

这是BCLer和Dxer通称的长波段。

在收音机里能听到的大多数信号是一些信标台不断重复摩尔斯（Morse）电码呼号.长波广播从153KHz启用，大功率的长波广播以俄罗斯和东欧国家为甚，非洲及澳大利亚、蒙古和前苏联加盟共和国等部分亚太地区国家也有长波广播，但我国广播并未染指这一领地。

法国标准时间标准频率发播台使用162khz.在长波的高端，可以接收到一些RTTY(无线电传）信号。

海洋气象和安全广播,如无线电爱好者熟知的VTEX(航行警告自动通信系统)就是在512KHz发射。

这个波段的最好接收时间是秋冬季的夜晚。

我国的北方地区容易接收到独联体国家的长波广播。

540KHz到1710KHz。

这是中波广播.亚洲和中南美洲地区的中波起始段被划为530KHz。

传统收音机的中波到1600KHz结束，而实际意义上的中波广播波段却在1710KHz结束。

从1610到1710KHz是新的中波扩展领域,从1997年开始,不断有电台在这一波段上播音,给无线电爱好者提供了精彩的DX（远程无线电接收活动)契机。

但1700khz以上频率入驻的中波广播电台寥寥无几，据WRTH(《世界广播电视手册》）最新记录，全球仅有两家广播电台在1700khz—-1710khz发声，澳大利亚转播当地赛马和服务偏远地区土著民的广播电台就使用1701KHz,阿根廷RadioPalacio—AM1710电台使用1710KHz,发射功率均在1KW以下，远程接收极具挑战性。
