#ISM DONGLE NOT INSTALLED SOFTWARE#

There’s a lot of options out there different programs that support different types of receivers, but since this article only deals with the RTL-SDR dongle based on RTL2832 chip, I will only cover the software that supports this particular receiver. The final part that is still missing is the software. After a while, you will get a message saying “Driver replaced successfully,” which means that the most difficult step is done and we can start using the RTL dongle as a receiver!

You will now be prompted a few times by the system, so just confirm that you trust this driver.

#ISM DONGLE NOT INSTALLED DRIVER#

Make sure WinUSB driver is selected in the second text box and click the button “Replace Driver”. If you replace driver of the wrong device, it will most likely stop working and it might be very difficult and time-consuming to get it back! Important note: before replacing the driver, double check that you have selected the correct device! For example, you can check the currently installed driver listed in the “Driver” field, and it should contain the string “RTL2832U”. You should now be able to select any of your USB devices, among which will be the RTL dongle, listed as “Bulk-In, Interface (Interface 0)”. In the Zadig tool, select “Options” from the menu and press “List All Devices”. Next, plug your RTL dongle to one of the USB ports. Download the exe file from here and run it. To get that driver, you will need to use Zadig – a tool that lets you replace a driver of a USB device.

#ISM DONGLE NOT INSTALLED INSTALL#

When you plug the RTL2832-based dongle to your computer, it will install the default driver, unfortunately, that’s not the driver that will allow you to use it as a software-defined radio. I’m using 1 m dipole antenna placed outside and running the signal using a coaxial cable and a USB cable. Antenna indoors will probably be able to receive powerful FM radio broadcast, but it might have trouble picking up a 433 MHz transmitter that is placed outside – even if it’s just a few feet away – and almost certainly it won’t be able to pick up weaker signals, such as satellite transmissions (we’ll get to those later). This may seem pretty straightforward, but it’s actually one of the most crucial steps. Once you have obtained the receiver, you will need an antenna and a place to put it. Those pre-process the signal for the digital components. For that reason, real SDR receivers use some hardware components, most commonly wide-band, low-noise amplifiers and band-pass filters. The main obstacle is the analog-to-digital converters turns out it is pretty hard to design a converter that can convert quickly and accurately enough, even signals at nanovolt level. Unfortunately, we don’t live in an ideal world. You could just hook up the antenna to the converter, feed the output to the signal processor, and voila you can process the data stream in a computer. In an ideal world, Software-Defined Radio (SDR) would require only three hardware components: antenna, analog-to-digital converter, and a digital signal processor.
