Aurora AU-510 500W Integrated SDR Transceiver

The Aurora AU-510 sets a new standard for integrated SDR performance, delivering a full-featured transceiver, 500W amplifier, automatic tuner, and power supply—all in one compact, high-efficiency chassis. At its core is a revolutionary 500W transmitter module operating at up to 80% efficiency, dramatically reducing heat, power consumption, and size—making it ideal for both local and remote installations.

Designed for use with SmartSDR clients on Windows, macOS, iPad®, iPhone®, or Maestro™, the AU-510 provides flexible control with no need for a built-in front panel or display. Its headless design makes it perfect for rack-mounted stations, remote HF sites, or minimalist setups that prioritize performance and simplicity. Radios are licensed for SmartSDR Basic.

The AU-510 is a single SCU (Spectral Capture Unit) radio. An SCU digitizes the RF spectrum for signal processing and display, supporting up to 2 slice receivers and 2 simultaneous panadapters, covering 30 kHz to 54 MHz in real time for complete visibility and control across the bands.

Inside the AU-510:

• 500W high-efficiency transmitter

• Integrated AC/DC power supply (80–264VAC input)

• Automatic antenna tuner

• SmartSignal™ adaptive predistortion for cleaner signals and reduced IMD

• Controlled Envelope SSB (CESSB): Up to 3 dB more talk power with no added distortion

• MultiFlex™: Enables simultaneous operation by two independent SmartSDR clients

With its fully integrated architecture, the AU-510 eliminates the need for separate amplifiers, tuners, and bulky power systems—delivering serious power and capability in a streamlined, ready-to-deploy form factor.
