AU-510 500W Integrated SDR Transceiver
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.
Features
- 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.
