XHSI (eXternal High-resolution Simulator Instruments) is an add-on for the X-Plane flight simulator that provides high-fidelity, external glass cockpit displays, enhancing the simulation experience by offering more readable and realistic instruments.

XHSI can also operate without being connected to X-Plane, both in Windows and Linux, using an RTL-SDR V3 dongle, an SDR device based on the RTL2832U and R820T2/R860 chips, designed to receive and decode radio signals across a wide range of frequencies, rtl1090, a free software developed by Jetvision, is used to convert signals received from an RTL-SDR (Software-Defined Radio) R820T or RTL2832U dongle into ADS-B (Automatic Dependent Surveillance-Broadcast) data that can be read and transmitted to other tracking software like PlanePlotter, Virtual Radar Server, or other monitoring tools. 

Operating systems: Can run on Windows with Java 1.5 or higher, MacOS and Linux

_______________

For the installation of the RTL-SDR dongle, go to the page  RTL-SDR V3

___________

If rtl1090 has never been installed or you want to have a clean installation click on New Install

The app is a bit dated and offers the choice between Windows Vista, 7, 8 or Windows XP.

Confirm the folder where you want to install or create a new one, with a right click of the mouse, on the right side. 

With a click on OK, the program automatically installs all the drivers and launches Zadig. 

With Zadig open, the app provides the necessary instructions to continue and complete the installation. After opening Options and enabling "List All Devices," you should see "Bulk-in..." or "RTL2838UHIDIR" at the top line in Zadig. At the end of the process, a message will confirm that everything was successful with "The driver was installed successfully." 

Or you can manually install the drivers with the procedure I explain now.

Manual installation and configuration of rtl1090 Version2

Visit the official rtl1090 website (https://rtl1090.com) and download Version 2 of the software.

rtl1090 Version 2 rtl1090.zip  

Version 2 brought significant improvements, introducing greater stability and compatibility with more RTL-SDR devices. It implemented smoother data transmission to external software like PlanePlotter and Virtual Radar Server. Additionally, it includes new options for filtering Mode-S messages, making monitoring more efficient. The interface has been improved while maintaining ease of use.

This is the original downloaded version that needs to be modified by adding some files (the same ones we added in Version 1):

• Download Zadig 

Zadig - USB driver installation made easy 

Zadig is a Windows application that installs generic USB drivers such as WinUSB, libusb-win32/libusb-1.0.dll, or libusbK, which are necessary for a wide range of USB devices to communicate with Windows. It is especially useful for RTL-SDR because standard drivers do not support this device. Download Zadig from the official website and launch the application.

Connect the RTL-SDR Device Before running Zadig, connect your RTL-SDR dongle to a USB port on your computer. This ensures that the device is ready and detected by Zadig.

Open Zadig and Select the RTL-SDR Device Once launched by clicking on Zadig.exe, Zadig should automatically detect the RTL-SDR dongle. Open the dropdown menu within the Zadig interface and select the device listed as "Bulk-In, Interface (Interface 0)" or a similar name. If the device does not appear in the list:

• Check your connections and make sure the dongle is properly inserted. If the device does not appear in the dropdown menu, proceed with the installation as long as "Install WCID Driver" is an option.
• If multiple dongles are present, repeat the process for each dongle.

Install the WinUSB Drivers With the device selected, proceed to install the WinUSB drivers by clicking on "Install Driver". This action will replace any existing drivers the dongle might be using with ones compatible with RTL-SDR operations. This step is crucial as it ensures that rtl1090 or any other SDR software can effectively communicate with the dongle.

Unzip the file ZIP rtl-sdr-release

Open directory x32

Copy the Files

Navigate to the extracted directory, specifically to rtl-sdr-release\x32. Locate the following files:

• rtlsdr.dll
• libusb-1.0.dll

Copy these files into the RTL1090 installation folder on your computer. The RTL1090 directory should contain these files to ensure proper functionality.

Launch RTL1090 and Verify Reception To test the setup:

1. Launch the rtl1090.exe File: Navigate to the folder where you have extracted and updated the RTL1090 software.
2. Run rtl1090.exe: Double-click on the file to start the software.

1. Launch RTL1090 and Verify ReceptionTo test the setup and begin decoding Mode-S or ADS-B signals:

   1. Start Decoding: Press the Start button to begin decoding either Mode-S or ADS-B signals. Note that you cannot receive both simultaneously with a single dongle; separate dongles are required for each.

   2. Verify Reception: Once the software is running, check that it is correctly receiving signals. If everything is configured properly, you should be able to see real-time data being transmitted from connected SDR devices.

   3. Improve Reception: Click on "Tuner AGC" (Automatic Gain Control) to enhance the reception quality.

   4. Check for Data: If the data is being correctly received, you will see a list of messages and identifiers of aircraft in the rtl1090 window.

   5. Error Handling: If you encounter an error stating "Index :0; Cannot Read device info:-12. Cannot find device," it means that the correct driver for the dongle inserted in the USB port has not been loaded.

      • Solution: Reinstall the correct driver using Zadig by selecting it from the Options > List all device menu.

Installation and Configuration of RTL1090 Version 3 (Scope)

Version 3, the latest and most advanced, introduced the "Scope" feature, which allows for graphical visualization of detected aircraft on the map. This tool displays a real-time radar, with aircraft represented on a grid, providing a more intuitive overview. It has been optimized for quicker and more accurate receptions for enthusiasts and advanced users. The interface has become more user-friendly, with advanced customization options.

This installation is easier if you start from an installed Version 2.

• Download: Visit the official rtl1090 website (https://rtl1090.com) and download the SCOPE version of the software.

rtl1090 RTL1090 Version 3 Scope rtl1090beta3.exe  13/4/2015

This version is an upgrade, so it requires the installation of Version 2 first.

Configuration of RTL1090 Software

To ensure that your RTL1090 software functions correctly, it is essential to install some support files. Here are the steps to configure your system:

Step 1: Download or Copy the Necessary Files

If you no longer have the original folder, download the file from the following link:

https://osmocom.org/attachments/download/2242/RelWithDebInfo.zip

Alternatively, if you already have the rtl1090 folder, use the files from there.

Step 2: Unzip and Copy the Necessary Files

Download the RelWithDebInfo.zip file, then proceed to unzip it and copy the necessary files.

Unzip the file ZIP in rtl-sdr-release

Apri la directory x32

Start RTL1090 and check reception

Start the rtl1090.beta3.exe file: Go to the folder where you extracted and updated the RTL1090 software.  Double-click the file to start the software.

rtl1090.beta3.exe supports error correction, so it should get more reports.

Press the Start button to begin decoding Mode-S or ADS-B signals. Note that you cannot receive both signals simultaneously; separate dongles are required.

Verify Reception: Once the software is launched, check that it is correctly receiving signals. If everything is set up properly, you should be able to see real-time data being transmitted from connected SDR devices.

Improve Reception: Open OPEN (top left of the screen) and Click on AGC Tuner to improve reception

Data Reception: If the data is being received correctly, you will see a list of messages and aircraft identifiers in the rtl1090 window.

Error Handling: If you encounter the error "Index :0; Cannot Read device info:-12. Cannot find device," it indicates that the correct driver for the dongle inserted in the USB port has not been loaded.

Solution: Reinstall the correct driver using Zadig by selecting it from the Options > List all device menu. This step will ensure that the correct driver is in place, allowing rtl1090 or any SDR software to effectively communicate with the dongle.
