FlexRadio 8400M HF/6-Meter Signature Series SDR Transceivers

SDR technology, paired with a high-resolution display and ergonomic controls. The FLEX-8400M combines all the capabilities of the FLEX-8400 with a stunning 8-inch 1920×1200 IPS WUXGA touchscreen and intuitive controls, delivering high-performance SDR functionality in a traditional radio interface. Unmatched band awareness comes from the integrated display, while support for external monitors at 1900×1200 resolution enhances spectral visibility.

Designed with input from top contest and DX operators, the symmetrical and independent dual VFO controls are strategically placed to maximize productivity across all operating styles. Fully self-contained, the transceiver requires no PC, network, or steep learning curve—just plug in and operate.

When connected to a PC, laptop, or Mac client, users can access up to two 7 MHz spectrum/waterfall displays and independent receivers, transforming how bands are viewed. 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 boxes needed.

FlexRadio's industry-leading SmartSDR™ software ensures compatibility across the entire FLEX-8000 Signature Series, enabling continuous software enhancements. With SmartLink™ technology, remote access is simple—just log in from any SmartSDR-compatible client, including an iPhone.
