今天雙十一后上學(xué)第一天偿警，就收到了來自老師的“禮物”：一個RTL-SDR軟件無線電接收機(jī)躏救。
大愛，感謝恩師螟蒸。
那么下面就講一講它的簡單安裝配置及使用盒使。

2皮假、SDRsharp下載
SDR#(也稱SDRSharp)與Linux平臺下常用的GQRX類似鞋拟，是目前Windows平臺上最常用的頻譜觀察，音頻解調(diào)軟件惹资，支持AM贺纲、FM、SSB等多種調(diào)制方式褪测。以SDRSharp為基礎(chǔ)又派生出了其它一些軟件比如TVSharp以及ADSBSharp等猴誊。

3、SDRSharp的安裝及驅(qū)動配置
3.1????解壓sdrsharp-x86.zip 到電腦上某個文件夾.?
3.2 ?? 從解壓的文件夾內(nèi)找到install-rtlsdr.bat侮措，雙擊安裝驅(qū)動及配置文件（This will start a command prompt that will download all the drivers?required to make SDRSharp work with RTL-SDR.It the bat file ran successfully the files?rtlsdr.dll and zadig.exe will be?downloaded into the SDR# directory. ）
zadig.exe是一個給你SDR接收機(jī)安裝usb驅(qū)動的工具懈叹。
3.3 ?? 待上一步執(zhí)行完成并自動消失后，插入接收機(jī)設(shè)備分扎，右鍵雙擊zadig.exe澄成，以管理員身份打開
3.4????In Zadig, go to "Options->List All Devices" and make sure this option is checked. If you are using Windows 10, in some cases you may need to also uncheck "Ignore Hubs or Composite Parents".
3.5????Select "Bulk-In, Interface (Interface 0)" from the drop down list. Note on some PCs you may see something like RTL2832UHIDIR or RTL2832U instead of the bulk in interface. This is also a valid selection.?
3.6????We need to install the WinUSB driver, so also ensure that WinUSB is selected in the box after the arrow next to where it says Driver (this is the default selection).?
4、SDRSharp的簡單使用
4.1 ?? 打開，設(shè)置信號源類型墨状。Open SDRSharp.exe and?set the "Source" drop down box to?'RTL-SDR (USB)'.?
4.2 ?? 點擊開始按鈕卫漫。Press the Play button (the right facing triangle).
4.3 ?? 調(diào)節(jié)增益。Don't forget to also adjust the RF gain settings by pressing the Configure button (looks like a cog) up the top next to?the Play button. By default the RF gain is set at zero. A gain of zero will probably receive nothing but very strong broadcast FM - increase the gain until you start seeing other signals.
