A preconfigured RC400L hotspot running Rayhunter for people who want visibility into suspicious cellular-network behavior without building the tool themselves.

Rayhunter RC400L is a refurbished Orbic RC400L mobile hotspot with the open-source Rayhunter IMSI catcher detection software installed, configured, and tested before shipping.

Rayhunter monitors cellular control-plane behavior and looks for anomalies associated with cell-site simulators, also known as IMSI catchers or Stingrays. These systems can masquerade as legitimate cell towers and may cause nearby devices to connect through them instead of the normal carrier network. Rayhunter is designed to give researchers, journalists, privacy-conscious users, activists, and civic-tech observers a practical way to notice suspicious cellular behavior in the field.

This is not a hacking gadget, interceptor, or spy tool. It is a passive awareness device that helps observe and log unusual cellular-network behavior that normal phones do not expose.

Why a prebuilt Rayhunter hotspot is useful

Rayhunter is open source, but setup normally requires finding compatible hardware, flashing or installing the software, confirming the device boots correctly, and verifying that logging works. This listing is for people who want the tool already installed on tested hardware.

Each unit is prepared as a dedicated, single-purpose field appliance: turn it on, let Rayhunter run, and use the hotspot display or web interface to review alerts and captures.

Key advantages

• Rayhunter installed and configured before shipping
• Tested RC400L hardware
• Passive monitoring only
• No rooted phone required
• No SDR setup required
• Runs on a small portable hotspot
• Useful for field observation, privacy research, journalism, and civic-tech work
• Gives visibility into cellular behavior that standard phones usually hide

What Rayhunter does

Rayhunter runs on the hotspot and monitors cellular control-plane activity. It looks for suspicious events and network behavior that may indicate a cell-site simulator or abnormal cellular environment.

Rayhunter can help surface signals such as:

• Suspicious base station behavior
• IMSI catcher indicators
• Cellular downgrade attempts
• Abnormal control-plane events
• Network behavior not normally visible from a phone

When Rayhunter is running, the device provides a simple visual status indicator on the hotspot display. The Rayhunter web UI can also be used to start or stop recordings, download captures, delete captures, and view heuristic analysis results.

Built for field use

This is a small, portable awareness device based on the Orbic RC400L hotspot platform. It is meant to be carried, powered on, and used as a dedicated cellular-environment observer.

It is especially useful for:

• Privacy-conscious users
• Journalists and documentarians
• Activists and community observers
• Security researchers
• Civic-tech researchers
• Radio and hardware hobbyists
• People studying cellular surveillance infrastructure
• Anyone who wants a practical IMSI-catcher awareness tool without assembling one from scratch

Device condition

• These are refurbished RC400L units.

Each device is checked for Rayhunter compatibility and basic operation before shipping. Cosmetic condition may vary. Minor scratches, wear, sticker residue, or other signs of previous use may be present.

This is used hardware repurposed into a privacy and research appliance.

What’s included

• Refurbished Orbic RC400L hotspot
• Rayhunter installed and configured
• Basic boot and logging test
• 1 battery
• Basic getting-started instructions

Optional add-ons may be available depending on stock:

• Spare RC400L battery
• Prepaid data SIM option

A SIM card and data plan are optional for basic Rayhunter monitoring functionality, but some use cases may benefit from having a SIM installed.

Using the device

Rayhunter starts automatically when the device is running. The device display shows a status indicator while Rayhunter records and changes the indicator if Rayhunter flags potential suspicious activity.

The web interface can be accessed from a phone or laptop connected to the hotspot network. From there, you can review alerts, manage recordings, and download captures for later analysis.

Important notes

Rayhunter is an awareness and research tool. It does not guarantee detection of every IMSI catcher, Stingray, rogue base station, or cellular surveillance system.

Detection depends on local network conditions, carrier behavior, supported bands, device compatibility, signal environment, and the limits of Rayhunter’s heuristics. Some suspicious events may have benign explanations, and some malicious or unusual systems may not be detected.

Rayhunter is passive. It does not intercept calls, texts, web traffic, or user communications. It does not modify cellular traffic or interfere with networks.

Use for lawful and ethical purposes only. This device is intended for privacy education, civic awareness, research, journalism, documentation, and public-interest monitoring. Do not use it to interfere with communications, evade lawful process, commit or flee a crime, harass individuals, or disrupt public or private infrastructure.
