R-330B Russian VHF Frequency Jamming System

Hezbollah Proliferation. The upgraded R-330B/R-330T VHF jamming system is designed for detection, direction-finding, and jamming of VHF communication facilities operated at tactical command level at fixed frequencies with conventional waveforms, in programmed and automatic frequency tuning modes, as well as for transmitting short encoded messages. The jamming system provides analysis and selection of emitters’ signal parameters. The R-330B/R-330T VHF jamming system consists of an equipment vehicle on a wheeled (R-330T) or tracked (R-330B) chassis, a diesel-electric power station mounted on a two-axle trailer (R-330T), or MT-Lbu armored tracked chassis (R-330B), a set of operational documentation, and a single spare part, tools, and accessories set. --- COGINT Report Data (7 June 2023, UNCLASSIFIED) --- Bandwidth/Frequencies: Operating frequency 30–100 MHz Additional Information: • Developed by TNIIR Efir (R-330B: 1999-2001) • System powered either by a towed ED-30 (ED30-T400-1RPM1) diesel generator or mains grid power converter R-330T / R-330B Performance Specifications: • Operational frequency range [MHz]: 30–100 • Azimuth search coverage [deg]: 360 • Frequency panoramic scan rate [MHz/s]: up to 7,000 • RMS direction-finding error [deg]: ≤ 2.5 • Transmitter output power [kW]: 1.0 • Jamming spectrum width [kHz]: narrowband: 2, 10, 20, 100 • Number of simultaneously jammed RF links: ≤ 3 at fixed frequencies • Detection-to-suppression time [ms]: ≤ 5
