Overview

FlexRadio Aurora 500W HF+6M SDR Transceivers

FlexRadio AURORA™ SERIES is an all-new family of HF + 6M transceivers featuring the world's first truly integrated 500 watt SDR transmitter. The Aurora Series defines a new category in amateur radio, eliminating the traditional boundaries between transceiver, amplifier, tuner, and power supply. Designed for the modern operator, the Aurora Series delivers exceptional RF performance in a radically compact form factor—leveraging cutting-edge high-efficiency technology that produces more power with less weight, lower heat, and dramatically reduced power input requirements.

Aurora Series transceivers are network ready, designed for remote access with SmartSDR clients on any Windows, macOS, iPad®, iPhone®, or Maestro™ device, in your shack, easy chair, or from virtually anywhere in the world!

All four Aurora versions offer full coverage reception of 30 kHz to 54 MHz in real time for complete visibility and control across the bands.

The AU-510/510M has a single SCU (Spectral Capture Unit) that digitizes the RF spectrum for signal processing and display, supporting up to 2 slice receivers and 2 simultaneous panadapters.
