The FLEX-6700™ Signature Series transceiver is based on a new hardware architecture and SmartSDR™ software platform. This hardware uses Digital Down Conversion (DDC) to convert from RF to digital and Digital Up Conversion (DUC) to convert from Digital to RF. The FLEX-6700 uses two Spectral Capture Units™ (SCU) for the RF to digital conversion and an ultra high performance on-board signal processing and control system to perform demodulation and modulation, filtering, and audio stream management. The result is incredible receiver dynamic range and received signal clarity.
The FLEX-6700 model transceiver utilizes two SCUs for reception from 0.70 to 77 MHz plus 135 to 165 MHz and the ability to create up to 8 full featured independent SLICE RECEIVERS. Optimized preselector filters can be selected for the ham bands for greater out of band rejection.
SmartSDR is the “ecosystem” of the radio platform. It organizes all the signal processing power in the radios into an advanced radio fabric. SmartSDR understands the capabilities of each SCU and how to harness its power. It also comprises of the “presentation layer” or GUI client that the user interacts with. The FLEX-6700 utilizes an Ethernet connection for high-speed “driverless” access to the graphical user interface (GUI).
The FLEX-6700 provides continuous duty 100W output across the entire 160-6m band. The FLEX-6700 also includes an automatic antenna tuner (ATU) capable of tuning antennas over 10:1 range (3:1 on 160m and 6m).
