The Vydun 7.5¶
A drone detector is sold on what it can hear, and the Vydun hears a great deal: four bands, the drone’s own video, and every phone that shares those bands with it. On the front it came from, a phone in range belongs to the enemy and nobody asks what the box keeps of it.
A handheld drone detector that puts the drone’s own video on its screen. UNITED24 Media described it on the 26th of March 2026, about four months after it entered service with Ukrainian units, and its specification lists what this detector receives.
A radio with a screen¶
The Vydun 7.5, made by the Ukrainian company Babai, scans four bands at once: 910 to 2200 MHz, 2200 to 4040 MHz, 4867 to 6100 MHz and 6000 to 7500 MHz. A cycle takes three to twenty seconds depending on interference and mode. It runs two algorithms, a fast sweep against an updated signal database and a step-by-step scan with adjustable increments.
It identifies hostile drones and intercepts their analogue video feeds at up to four kilometres with 360-degree coverage, and shows the feed on a 4.3-inch screen while a second display shows the detected frequencies. Its director said: “It displays on the screen, while video scanning runs in the background, and if detected, the operator can instantly switch between channels.”
A 10,000 mAh battery gives six to eight hours; it charges from a socket, a car or a power bank; firmware arrives remotely, “like a phone”. Dozens of units, potentially approaching a hundred, were at the front. LoRa reception was removed for now because it overloaded the processor and drained the battery.
By September 2026 Babai’s own shop lists the 7.5 at 39,000 hryvnia beside an 8.2 at 47,000 and a Vydun 8.5 at 49,000. The 8.5 keeps the three lower bands and pushes the top one to 6000 to 8800 MHz, hears a drone at up to four kilometres on the lower bands and three on the top one, keeps the 4.3-inch video screen and adds a 2.4-inch one for status, runs five to six hours on the same battery, and filters LTE, Wi-Fi and Bluetooth as the 7.5 does.
The device filters civilian signals, LTE, Bluetooth and Wi-Fi, to reduce false detections.

It heard the phones first¶
A drone detector is a wideband receiver with a screen. It receives the phones before it filters them. The filter is a feature against false alarms.
The attacks D1 and D6 are both on this one device: the feed on the screen, the bystander in the filter. A device that goes from first design to the front in three months and updates over the air is built like a consumer product.
