In order to be able to record more than one broadcast at once, you pretty much need to have an SDR that has enough bandwidth to cover the lowest channel in the system and the highest on at the same time.

#Rtl sdr dongle wxtoimg code#

It contains all the code to work with the device from Matlab.Įxample: to tune to 88.5Mhz and set the sample rate to 2.Most trunked radio systems have the channels they use spread out over a couple MHz worth of spectrum.

I will release GNU octave code soon.ĭownload and extract the archive rtlsdr/rtlsdr_matlab.zip. Unfortunately these do not work in GNU octave as they use Matlab built-in java interpreter. I've written several matlab functions that canīe used to interact with the device directly from Matlab. Rtl_tcp which enables communication with the device over TCP connection. Then, reading the data from a file into Matlab. The most simple way is using the rtl_sdr executable There are a couple of ways to capture data and transfer it into Matlab.

So you could use one USB port for RTLSDR and another port for using the dongle to watch DVB-T with the supplied Windows application.

#Rtl sdr dongle wxtoimg driver#

It seems that you can change which driver is loaded depending on the USB port used. Note that if you insert the dongle into a different USB port you may have to use Zadig again. Before you proceed make sure the USBID matches the VID/PID. The big button underneath will say “Replace Driver” or “Reinstall Driver”. In the box to the right of the green arrow make sure “WinUSB” is chosen - not libusb or libusbk. This should be the primary endpoint of your RTL device: Run the Zadig.exe file and you should see the following with an empty list:Ĭlick on Options and select “List All Devices”:Ĭhoose the one that says “Bulk-In, Interface (Interface 0)”.

#Rtl sdr dongle wxtoimg install#

Don't install the software on the CD that comes with the device. Plug your RTL device in for the first time, Windows may request a driver or automatically install a driver from Microsoft - this is OK as it will be replaced in the next few steps. these correpond to 32bit and 64bit rtl_sdr binaries. You should see the file zadig.exe and two directories: x32 and 圆4. Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle If they do not exist, in the terminal, create the following directories. You should see the files: rtl_sdr, rtl_tcp, rtl_test, librtlsdr.dylib, librtlsdr.0.dylib,librtlsdr.0.0.0.dylib, libusb-1.0.0.dylib. Rtl_tcp: networked interface which we will use to dynamically load data into Matlab, change frequency etc.ĭownload and extract the archive rtlsdr_osx.zip Rtl_sdr: enables saving raw samples into a file Rtl_test: this will test the device and its function. There are three tools you must be able to run: There are instructions there to install additional software, such as GNU-radio or SDR If you are bold, you can go to the aove websites and follow the installation instructions. Here, we will provide you with binaries and basic installation that will enable you to get tune to a frequencyĪnd get samples into Matlab or GNU Octave. Driver Installation InstructionsĪll the installation instructions below were derived from the following links: The device uses IQ baseband demodulation and sampling. In our case, the RTL2832U chip serves as an analog to digital converter that samples the baseband signal and outputs the samples to a host computer through a USB2 port. The tuner selects a frequency band around a target center frequency and demodulates it to baseband. The E4000 Elonics chip is a digitally controlled tuner. This feature enables this device to be used as an inexpensive ”Software Defined Radio”. Last February, a V4L/DVB kernel developer, Antii Palosaari, discovered that there is a device mode in which raw samples can be captured and transferred to a host computer. This dongle was originally made to receive and decode the European standard digital television. The rest of the processing is done solely in software.Įach student in the class will/or already gotten a TVB-T USB dongle based on the Realtek RTL2832U chip. It consists of an RF front-end followed by and analog- to-digital converter which provides samples to a host computer. A software defined radio system is a system in which the components are implemented in software instead of the traditional way of hardware implementation.
