  • Integrated Display & Controls: The “M” models (8400M and 8600M) feature an 8-inch capacitive touchscreen with an intuitive front panel, allowing for standalone operation without a PC. The non-M models (8400 and 8600) require an external control interface like a PC running SmartSDR or the Maestro control console.
  • Receivers & SCUs: The FLEX-8600 series boasts four slice receivers and two SCUs, enabling advanced operations like diversity reception and true SO2R. In contrast, the FLEX-8400 series offers two slice receivers and a single SCU, suitable for standard operations.
  • Filtering: The FLEX-8600 series is equipped with 7th order bandpass filters on contest bands, providing superior adjacent signal rejection. The FLEX-8400 series utilizes 3rd order filters, which are adequate for general use.
  • Antenna Connectivity: The FLEX-8600 series includes two receive-only antenna ports (RXA and RXB), facilitating advanced configurations like diversity reception. The FLEX-8400 series provides a single RXA port.
  • Transverter Support: With two transverter ports, the FLEX-8600 series simplifies integration with multiple transverters, ideal for satellite or VHF/UHF operations. The FLEX-8400 series includes one transverter port.
  • Audio Inputs: The FLEX-8600 series features a balanced XLR/TRS microphone input, catering to high-quality audio setups. The FLEX-8400 series lacks this feature.
  • FLEX-8400: Ideal for operators seeking a cost-effective, high-performance SDR with remote operation capabilities via SmartSDR or Maestro.
  • FLEX-8400M: Suited for those who prefer a traditional radio interface with an integrated display, eliminating the need for external devices.
  • FLEX-8600: Designed for advanced operators requiring multiple receivers, diversity reception, and robust filtering for contesting and complex setups.
  • FLEX-8600M: Combines the advanced features of the 8600 with an integrated display and controls, offering a comprehensive standalone solution.
