AU-510M 500W Integrated SDR Transceiver with Maestro Front Panel

The AU-510M redefines HF/6m operation—combining a full-featured SDR transceiver, 500W amplifier, power supply, and tuner into one compact, high-performance chassis. It’s the world’s first truly integrated 500W software-defined radio, engineered for today’s most demanding amateur radio operators.

At the core is a groundbreaking 500W transmitter module operating at up to 80% efficiency, delivering more power with less heat, lower input demands, and a dramatically lighter footprint—all within the size of a typical 100W PA system.

The AU-510M includes a built-in Maestro front panel, just like the FLEX-8600M, offering full touchscreen control, responsive knobs, and an all-in-one user experience—no PC required. Whether you’re in the shack, on the road, or operating remotely, the AU-510M puts advanced SDR performance at your fingertips.

The AU-510M is a single SCU (Spectral Capture Unit) radio—ideal for most operating needs. An SCU is the part of the radio that digitizes the RF spectrum, enabling slice receivers, panadapters, and digital signal processing. A single SCU supports up to 2 slice receivers and 2 simultaneous panadapters, simultaneously covering from 30 kHz to 54 MHz, offering plenty of flexibility for everyday operating, DXing, or contesting.

Inside every AU-510M:

  • 500W high-efficiency transmitter
  • Integrated power supply (80–264VAC input)
  • Automatic antenna tuner
  • SmartSignal™ adaptive predistortion for enhanced spectral purity and reduced IMD
  • Controlled Envelope SSB (CESSB): Up to 3 dB more talk power with reduced peak-to-average ratio—boosting signal presence without distortion
  • MultiFlex™: Dual-operator capability with independent SmartSDR sessions—perfect for contesting, remote ops, or shared stations

With everything built in—transmitter, tuner, amplifier, power supply, and front panel—the AU-510M eliminates bulky gear and external cabling, delivering true plug-and-play power and performance.

Ideal for remote HF projects, the AU-510M’s compact design, low heat output, and single-plug AC input make it easy to deploy in off-grid or hard-to-access locations—bringing serious power to your remote station with unmatched ease.
