World CB, global online CB radio

A Citizen Band without borders

CB stands for Citizen Band: a radio system that let people speak directly through transceivers for decades. Operators choose a shared channel, listen, identify themselves with a Call Sign and press the PTT to talk.

CB radio is normally half-duplex, so one person speaks at a time. It created a culture of listening, radio language, shared channels and communities meeting on the same airwaves. World Citizen Band extends that idea to the whole world.

The technical difference is clear: traditional CB uses radio waves and physical frequencies. World CB uses the Internet, WebRTC and global virtual channels. Its PTT, Call Signs, listening discipline and half-duplex flow preserve the experience and culture of CB radio.

How World CB works

1. Choose a radio name—your Call Sign.
2. Enter the Radio and select a channel.
3. Listen to the operators already there.
4. Hold the PTT and wait for the short beep.
5. Talk, then release the button to listen again.

As on a radio set, one operator speaks on a channel at a time. That simple rule keeps conversations orderly and immediate.

99,999 virtual channels

World CB provides 99,999 numbered channels, from 1 to 99999. They are not radio-spectrum frequencies: they are digital spaces where operators can meet and talk.

You can enter a channel number directly or browse active channels to find someone listening.

Push-to-talk, radio style

The large PTT is at the heart of the experience. Hold it, wait for the beep confirming the channel is open, speak and release. When you are not transmitting, the station immediately returns to listening.

The beep is functional: it indicates that the audio path is ready and you can start talking.

From a phone or computer

World CB runs in a modern browser without a dedicated app. It works on supported smartphones, computers and tablets with a microphone and an Internet connection.

The interface keeps the same radio language on every screen while adapting its controls for touch and available space.

Direct communication when possible

Voice travels over WebRTC. Devices connect directly whenever the network allows it. On restrictive or mobile networks, an encrypted technical relay may carry the stream when a direct path is unavailable.

This improves connectivity without promising universal compatibility across every network, browser or device.

A radio experience, not a social network

World CB has no feed, likes, followers or algorithm choosing what you hear. It does not require a traditional personal account: choose a Call Sign, select a channel and listen to the people there.

Its value comes from a live voice conversation in the present moment—not from a volume of stored content.

Privacy by design

No advertising, application profiling or ad tracking. World CB does not record conversations and processes only the technical data needed to operate the station.

Details, retention periods and technical providers are described in the Privacy notice.

An experimental project

World CB is an experimental, free and non-commercial project by Studio Scivoletto. It explores radio for the Internet age: one voice, one channel and people meeting on digital airwaves.
