WebSDR (Web Software-Defined Radio) is a technology that enables remote control of software-defined radio receivers over the internet. It allows users to listen to radio signals from around the world and interact with them through a web browser. WebSDR systems are often created by individuals, radio amateur clubs, or institutions and offer radio enthusiasts a way to explore different frequencies and modes without physical equipment.

 Configuring a WebSDR system involves a number of steps, including hardware, software, and network considerations. Here's an overview of how to compile WebSDR:

 

Hardware Requirements:

 

Software Defined Receiver: You will need an SDR receiver such as an RTL-SDR adapter, Airspy, HackRF, or similar that can capture a wide frequency range.

 

Computer: A computer (preferably a standalone computer) that hosts the WebSDR software and controls the SDR receiver.

 

Antenna: A suitable antenna connected to the SDR receiver to pick up radio signals.

 Internet connection: A stable and relatively fast Internet connection is required to stream  SDR data to users. 

 

Software Requirements

 

WebSDR Software: Several open-source WebSDR software are available. Examples include "WebSDR" of PA3FWM and "KiwiSDR" of SK2LRW.

 

Web Server Software: To host the WebSDR interface, you need web server software such as Apache or Nginx.

 

Audio Streaming Software: Software for streaming audio from an SDR receiver to users' web browsers.

 

To Configure WebSDR:

 

Install The Software: Install  WebSDR, web server, and audio streaming software on your computer.

 

WebSDR Software Setup: Set the parameters of your SDR receiver in the WebSDR software, such as frequency, mode, bandwidth, and antenna. Also, configure the user interface settings.

 

 

Connect The Hardware: Connect the SDR receiver and antenna to the computer.

 

Audio Broadcasting: Configure audio streaming software to send SDR audio to users' browsers.

 

Web Interface: Configure the WebSDR interface as desired. It is an interface that allows users to control the SDR and listen to signals.

 

Network Settings: Make sure your computer is accessible from the internet. This may include setting up a router for forwarding and configuring a domain name or dynamic DNS.

 

Security: Protect your WebSDR system from unauthorized access and ensure user privacy by using appropriate security measures.

 

Testing: Test your WebSDR system to ensure it works as expected and provides a good user experience.

  

It is important to note that setting up a WebSDR system can be complex and requires a good understanding of software, network, and radio technology. Additionally, hosting a public WebSDR may require compliance with appropriate regulations and licenses, depending on your location and frequencies. Before installing WebSDR, thoroughly research the available software options, read the installation guide, and consider asking for help from experienced individuals or communities in the radio and SDR hobbyist communities.
