# BlueBird Tech 'upgrades' the 'Chuyka 3.0' drone detector: a fourth frequency band and an expanded spectrum

## 🎯 Key Points

- BlueBird Tech has launched an upgrade for the 'Chuyka 3.0' drone detector that expands the device's frequency capabilities.
- After the upgrade, the 'Chuyka 3.0' gains a fourth band of 6–8.8 GHz, while the 3.3 GHz band is extended to 2860–4500 MHz.
- The upgrade is available for models purchased from April 2026 onward (version 1.3.8); engineers are working on supporting other versions.
- The upgrade takes up to two weeks; sign up via the BlueBird Tech mobile app or the company's managers.

BlueBird Tech has announced the launch of an upgrade program for owners of the portable drone detector 'Chuyka 3.0'. According to the publication, the upgrade expands the frequency capabilities of already-released devices without the need to purchase new equipment. Open-source photographs show that the detector is a compact unit with several antennas, including a distinctive blue three-pronged antenna marked 'BlueBird', and a display showing a radar-style picture. The device is placed in a protective case with foam cradles, underscoring its field, mobile-purpose design.

### A fourth frequency band and spectrum expansion

The key innovation of the upgrade is the addition of a fourth frequency band to the 'Chuyka 3.0': from 6 to 8.8 GHz. At the same time, the existing 3.3 GHz band is also widened: where it previously covered the 2870–4080 MHz interval, after the upgrade its boundaries shift to 2860–4500 MHz. Taken together, this means the device begins to 'see' a noticeably wider frequency spectrum and now operates across four bands instead of three. For a video-signal detector aimed at intercepting and detecting FPV drones, this increases the likelihood of capturing communication and video-transmission channels that operators are increasingly shifting into new frequency windows to evade countermeasures.

### How the upgrade is carried out

The procedure follows a 'bring it in — get it back' principle. If needed, the user hands over their 'Chuyka 3.0' to the BlueBird Tech team, where engineers install an additional module for the new band, the corresponding antenna and battery, and also upgrade the existing 3.3 GHz module and antenna. Once the work is complete, the owner receives their own device, but now with expanded specifications. This approach preserves the serial identity and calibration of the specific unit rather than replacing it with a new one, which matters for users accustomed to the particular settings and interface of their detector.

### Who can get the 'upgrade' and how long it takes

An important limitation: as of now, the upgrade is available for 'Chuyka 3.0' models purchased from April 2026 onward, specifically for firmware version 1.3.8. That said, it is noted that engineers are already working on extending the upgrade option to other versions of the device. The estimated upgrade time is up to two weeks. Owners can sign up for the update through the BlueBird Tech mobile app or directly through the company's managers. This creates a 'development-as-a-subscription' model for the detector market, in which the initial purchase becomes an entry point into a line of subsequent improvements.

### Context: why the frequency upgrade matters now

Expanding the detector's frequency capabilities fits into the broader context of escalating drone warfare, in which both sides constantly change the communication frequency windows of FPV aircraft to evade electronic warfare and interception systems. Ukrainian media previously reported on the introduction of the first jet-powered drone interceptor into service and on the completion of development of the first gliding bomb KAB 'Vyравnovatel' (Balancer) after a year and a half of work. Against this backdrop, the detector's ability to 'see' a wider spectrum — from 3.3 to 8.8 GHz — becomes a practical tool for air-defense operators and field teams who need to detect enemy drones' video-transmission channels in advance.

## ❓ FAQ

### Q: What does the 'Chuyka 3.0' upgrade provide?
**A:** The device gains a fourth frequency band of 6–8.8 GHz, and the 3.3 GHz band is expanded from 2870–4080 MHz to 2860–4500 MHz, meaning the detector now operates across four bands and a wider spectrum.

### Q: Which models can be upgraded?
**A:** As of now, the upgrade is available for 'Chuyka 3.0' models purchased from April 2026 onward, version 1.3.8. BlueBird Tech engineers are already working on extending support to other versions.

### Q: How long does the upgrade take and how do I sign up?
**A:** The estimated time is up to two weeks. You can sign up through the BlueBird Tech mobile app or via the company's managers; the user hands over their device, and after installation of the additional module, antenna and battery, receives it back with expanded specifications.
