Overview

FlexRadio 8600M HF/6-Meter Signature Series SDR Transceivers

FlexRadio 8600M HF/6-Meter Signature Series SDR Transceivers deliver top-tier performance through direct sampling SDR technology. Paired with a high-resolution display and ergonomic controls, the FLEX-8600M is an ideal choice for serious HF and 6-meter operators. It combines all the capabilities of the FLEX-8600 with a vibrant 8-inch 1920×1200 IPS WUXGA touchscreen and intuitive physical controls, offering high-performance SDR functionality in a traditional radio interface. Integrated display support provides unmatched band awareness, while compatibility with external monitors at 1920×1200 resolution enhances spectral visibility for advanced operations.

The 8600M supports Adaptive Predistortion and includes a built-in antenna tuner, 10 MHz reference input, and an integrated GPS receiver with antenna to maintain frequency stability without manual adjustment. An optional GPSDO module is available for ultra-high frequency precision and accuracy. (sold separately)

The FLEX-8600M features direct sampling SDR at 245.76 Msps with 16-bit resolution, achieving 115 dB RMDR at 2 kHz and >155 dB dynamic range. It supports 100W PEP HF-6m operation across all modes and bands, with contest-grade band filters offering >50 dB rejection for superior signal isolation.

Operators can utilize four independent 14 MHz spectrum/waterfall displays and four independent band/mode receivers, offering game-changing band awareness. The transceiver supports full duplex cross-band operation on two antennas, allowing simultaneous transmit and receive on different bands without external equipment. It also enables true diversity reception to improve weak signal detection in high interference environments.

Additional connectivity includes two receive-only ports and two transverter/exciter ports, which can also serve as receive antenna inputs. The FLEX-8600M provides an economical SO2R solution with OTSPR support, enabling a complete legal-limit, all-mode SO2R station when paired with the Power Genius XL LDMOS solid-state amplifier—requiring only one radio, one amp, and three cables. (amp and cable sold separately)

FlexRadio's SmartSDR™ software ensures compatibility across the entire FLEX-8000 series and supports continuous software enhancements. With SmartLink™ technology, users can access their radio from anywhere using any SmartSDR-compatible client with just a login and password—even from an iPhone.
