What kind of device is this?

The “Hrets XL” modular electronic warfare system by BlueBird Tech is an EW solution designed to counter FPV drones and other UAVs by suppressing control and data transmission channels. The system consists of separate independent modules, allowing flexible configuration of frequency ranges to address specific threats. It supports control via a remote unit, channel status indication, calibration, and quick module replacement without fully shutting down the system.

Functions

Blocking of control and data transmission channels. Operates within selected frequency ranges: 170–1050 MHz / 2080–2720 MHz (depending on installed modules).
Modular system configuration. Allows installation of 2 to 10 modules with customizable frequency combinations based on mission needs.
Remote control operation. Supports simultaneous activation of all channels or individual control of each module.
Status LED indication. Each channel features an indicator showing standby, active operation, error, or calibration modes.
Replaceable modules. Individual units can be swapped without replacing the entire system.

Operating principle

After being connected to a power source, the system activates and enters operating mode.
The operator can switch on all channels simultaneously or select individual frequency ranges according to the installed module configuration.
The system then begins generating interference within the selected frequency bands, affecting UAV control and data transmission channels.
Each module operates independently, ensuring stable system performance even when the configuration is changed or individual units are disconnected.
LED indicators on the control unit display the real-time status of each channel.
If the configuration is changed or a module is replaced, channel calibration is performed to ensure correct system operation.
The device operates continuously, maintaining the specified parameters within the selected frequency ranges.

The Modular EW “Hrets XL” system is an electronic warfare solution designed to counter FPV drones and other UAVs. The device is used to suppress control and data transmission channels across various frequency bands. The system is suitable for mobile crews, field positions, logistics operations, and vehicle protection during missions.

What frequency bands does the modular EW “Hrets XL” system support?

The system supports up to 12 selectable frequency bands: from 170 MHz to 1050 MHz and from 2080 MHz to 2720 MHz. Additional anti-drop modules for 2.4 GHz, 5.2 GHz, and 5.8 GHz can also be installed. The minimum configuration includes 2 modules, while the maximum includes 10. The specific set of frequency bands is selected according to the type of detected threats.

What power source does the “Hrets XL” system use, and is a charging station required?

The system supports power input from an autonomous 12–36 V source as well as from a 220 V power supply. The “Genera-1200” charging station is an optional accessory: one unit is required for configurations with up to 5 channels, and two units are required for systems with 5 to 10 channels.
