U20552 Used FlexRadio Flex-6700 HF/50MHz SDR Transceiver

U20552 Used FlexRadio Flex-6700 HF/50MHz SDR Transceiver

This pre-owned FlexRadio Systems FLEX-6700 Software Defined Radio (SDR) transceiver is in near-mint condition with zero cosmetic blemishes, scratches, or defects. The anodized black aluminum front panel, integrated rack handles, and laser-etched lettering are spotless. The front OLED diagnostic display illuminates with sharp clarity, and the multi-direction navigation keypad, power switch, 8-pin foster microphone jack, 1/4" headphone jack, and key jack are in pristine shape. The rear brushed connection panel features clean SO-239 antenna jacks (ANT1 and ANT2), gold-plated BNC ports (transverter, RX antennas, 10 MHz reference), balanced XLR/TRS audio input, RCA keying/interfacing jacks, dual USB accessory ports, Gigabit Ethernet jack, and an undamaged Anderson Powerpole DC connector. It comes complete with a handheld microphone, Anderson Powerpole DC power harness, Ethernet cable, the printed Quick Start Guide, and the original FlexRadio factory carton.

The FLEX-6700 is FlexRadio’s flagship Signature Series direct-sampling SDR transceiver, engineered for elite DXing, competitive contesting, and sophisticated multi-operator/multi-receiver station environments. Covering 160 meters through 6 meters (plus 2-meter VHF reception/low-power drive capability), it is built around dual independent, synchronous direct-sampling Spectral Capture Units (SCUs) utilizing 16-bit A/D converters operating at 245.76 Msps. This architecture enables true diversity reception across separate antennas and up to 8 independent Slice Receivers simultaneously, each with its own real-time high-definition panadapter and waterfall display spanning up to 14 MHz wide. Delivering 100 Watts of clean PEP RF output across all HF bands and 6M, the FLEX-6700 operates over native Gigabit Ethernet using SmartSDR software on Windows, iOS, or via a Maestro console, allowing seamless local or remote station operation anywhere with zero external interface boxes.

Condition

• Cosmetic Condition: Pristine condition throughout with no scratches, scuffs, or signs of wear on the cabinet, front bezel, or handles.
