The Nautel NX2.5 is a compact 2.5kW rack-mount AM transmitter with six-phase digital modulation, hot-pluggable 250W RF modules, HD Radio MA3 and DRM support, and built-in RF instrumentation for low-power medium wave broadcasting.
The Nautel NX2.5 is a professional low-power AM transmitter designed for both analog and digital medium wave broadcasting. Built on Nautel’s proven NX Series platform, it delivers 2.5 kW carrier power in a compact rack-mount format and operates across 531-1700 kHz into a 50-ohm load. Its six-phase direct digital modulation architecture with digital precorrection provides the linearity and spectral cleanliness needed for modern AM services.
The Nautel NX2.5 is specifically engineered for digital transmission, supporting HD Radio including MA3 all-digital mode as well as all current DRM configurations. Front-accessible, hot-pluggable 250W RF power modules contribute equally to the final output, allowing on-air servicing and modular redundancy. Titanium-grade switching power supplies operate at 96% efficiency, helping reduce operating costs while maintaining reliable performance in continuous service.
An HTML-based Advanced User Interface provides local and remote monitoring through a standard web browser. Built-in real-time RF instrumentation includes spectrum and impedance measurement, reducing the need for external test gear during setup and maintenance. The compact chassis makes the Nautel NX2.5 well suited to stations needing digital-ready AM transmission in space-constrained sites.
