Nautel Introduces NX1 and NX2.5 Low‑Power AM Transmitters

NX digital performance comes to lower-power AM broadcasters for the first time.

Hackett’s Cove, Nova Scotia and NAB Booth C2546 — Nautel today announced the expansion of its proven NX Series of AM transmitters with two new digital/analog low‑power models: the NX1 (1 kW) and NX2.5 (2.5 kW). These transmitters bring Nautel’s most advanced AM modulation and digital transmission capabilities to lower power levels for the first time.

The NX1 and NX2.5 are built on the same NX Series architecture used in more than 40 MW of high‑power AM deployments worldwide. The new products are enabled by a new 250 W RF power module specifically developed to deliver NX‑class performance in low‑power configurations. This new module extends the NX Series’ ultra‑linear modulation, digital precorrection, and operational redundancy to the low-power AM market.

NX1 and NX2.5 are the industry’s first low‑power AM transmitters specifically designed to support digital transmission. Both models support HD Radio, including MA3 (all‑digital) operation, as well as all current DRM modes, enabling broadcasters to deploy digital services with confidence. Advanced digital precorrection and Nautel’s six‑phase direct digital modulation architecture deliver exceptional linearity and spectral cleanliness for both analog and digital operation.

The products have a modular, fully digital design with front‑accessible, hot‑pluggable RF power modules that contribute equally to the final output. This approach supports on‑air serviceability, high efficiency, and long‑term reliability. Nautel’s HTML‑based Advanced User Interface (AUI) provides comprehensive local and remote monitoring, while built‑in real‑time RF instrumentation—including spectrum and impedance measurement—offers deep system visibility without external test equipment.

“Low-power AM transmitters haven’t had these kind of capabilities in the past,” said John Whyte, Nautel Head of Marketing and Product Strategy. “With our new 250‑watt RF module, we were able to extend our proven NX architecture into the low‑power AM market without compromising performance. It’s exciting to be able to bring exceptional linearity, digital operation, and high efficiency to these broadcasters.”

The NX1 and NX2.5 low‑power AM transmitters will be available in Fall 2026 and will be shown at Nautel’s NAB Booth C2546. For more information, visit www.nautel.com
