FlexRadio 8400ATU Signature Series HF/6-Meter SDR Transceivers
FlexRadio 8400ATU Signature Series SDR Transceivers offer the latest in high-performance, direct sampling software-defined radio (SDR) technology designed for the HF and 6-meter amateur bands. Designed for hams who operate exclusively via remote access, the FLEX-8400 is engineered as a server-based SDR transceiver. It supports SmartSDR clients on Windows, Mac, iOS, and Maestro, allowing seamless control from virtually anywhere. With dual independent receivers and full duplex cross-band capability, it's ideal for DXing, contesting, and digital modes—no external sound cards or interfaces required. The integrated automatic antenna tuner (ATU) is designed to match antennas with up to 3:1 SWR on 80–10 meters and up to 2.5:1 SWR on 160 and 6 meters. Using a PC, laptop, or Mac client, the FLEX-8400 supports up to two 7 MHz spectrum/waterfall displays and independent receivers, providing enhanced band visibility. Both receivers can operate simultaneously on any band and mode, with instant QSY between VFOs. Digital mode operation is streamlined—no sound cards, cables, or external interfaces required. The radio delivers advanced band awareness, low phase noise, brick wall filters, and high-quality audio performance to support a wide range of operating styles.
