The Nautel VX300 – 300 W FM Solid-State Transmitter offers high efficiency, intuitive control, and Nautel’s renowned reliability for professional FM broadcasting.
Product Description
High Efficiency and Compact Design
The Nautel VX300 – 300 W FM Solid-State Transmitter combines proven Nautel engineering with modern efficiency and simplicity. Designed for regional, community, and translator sites, the VX300 delivers full-featured broadcast performance in a compact 2 RU package that’s easy to install and maintain.
Outstanding RF Performance
The VX300 provides 300 watts of continuous RF output using rugged solid-state LDMOS amplification. Precision DSP-based modulation ensures excellent audio quality, high spectral purity, and stable deviation across the entire 87.5 – 108 MHz FM band. AC efficiency typically exceeds 70 %, reducing heat and long-term operating cost.
Advanced Control and Monitoring
An integrated web GUI and SNMP support enable local or remote operation from any browser. Parameters such as forward/reflected power, PA current, and temperature are clearly displayed. Automatic protection circuits guard against VSWR, over-temperature, and power anomalies to maintain continuous 24/7 transmission.
Built for Reliability
Like all Nautel products, the VX300 is designed for durability and low service overhead. The power amplifier module and power supply are easily field-replaceable, and intelligent fan speed control minimises acoustic noise. Its solid-state architecture and self-diagnostic design make it an ideal low-power main or standby transmitter.
Flexible Broadcast Applications
The Nautel VX300 suits small-market broadcasters, gap-filler or relay stations, and as a reliable backup in larger networks. Its compact footprint, modern interface, and legendary Nautel reliability make it a solid choice for professional FM operations.
