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. Fasten in place with the nut and washer provided.6. ( ) Mount potentiometer R7 orientating the lugs as shown in the pictorial diagram Fig 1. Fasten in place with the nut and washer provided.7.

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。
