Meeting Notes
From the January 2026 issue of The Repeater.
7:00 pm meeting opened by VP Allan Taylor, K7GT.
Presentation over Zoom by Mike Walker, VA3MW, on the Flex Radio Aurora 500 Watt Integrated SDR Transceiver. Due to the increase in noise floor in urban locations these days, higher power than the old 100W is now more useful. The new radio produces 500Watts, but is lighter, claimed to be 18 Lb, and more power efficient, at 80%, than older design 500W rigs.
Device overview from their website:
- 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.
- Pricing runs from $6200-9600 depending on SCU (Spectral Capture Unit) and front-panel options. Each SCU covers the 30 kHz to 54 MHz range.
