Note
The FLEX-6300 is a software-defined transceiver and the entry-level model in FlexRadio Systems' 6000 Signature Series. It is designed as a simpler and more economical SDR option.
Features
– Software-Defined Architecture: The radio is highly integrated with SmartSDR for Windows software, which runs on a user-supplied PC and is updated several times a year with new features and bug fixes.
– Direct Sampling:** It utilizes an analog-to-digital converter (ADC) that produces 122 million 16-bit samples per second (Msps), sampling the RF spectrum up to 54 MHz.
– Includes a single Signal Capture Unit (SCU).
–Supports up to two panadapter/waterfall displays and two receivers simultaneously.
– Operates in "wide" mode across the spectrum as it does not include preselectors.
– Spectral Visualization: Allows users to visualize a large swath of the spectrum and click on any point to demodulate signals in SSB, CW, AM, or FM modes.
– Digital Processing: Uses a Xilinx Virtex-6 FPGA for high-speed DSP operations and a DaVinci Processor (ARM Cortex-A8) for filtering and signal demodulation.
– Connectivity: Communicates with the PC via an Ethernet connection (minimum 100 Mb/s) and uses custom DAX drivers for two-way digital audio.
Specifications
– Frequency Coverage: Receive: 0.03–54 MHz; Transmit: 160, 80, 60, 40, 30, 20, 17, 15, 12, 10, and 6 meter bands.
– Power Output: 100 W (CW/SSB/FSK/FM); 25 W (AM).
–Modes: SSB, CW, AM, synchronous AM, RTTY, FM.
– Power Requirements: Receive: 1.7 A typical; Transmit: 23 A max at 13.8 V dc ±15%.
– Receiver Noise Floor (MDS): –121 dBm (preamp off), –125 dBm (10 dB preamp), –136 dBm (20 dB preamp).
– Image Rejection: >80 dB.
Optional Accessories
6300-ATU: An optional internal automatic antenna tuner.
FlexControl: A USB tuning knob for users who prefer a physical dial over mouse-based tuning.
