Second Hand FLEX‑6400 SDR Transceiver with SDR+ V4.15 Update

Second Hand FLEX‑6400 SDR Transceiver with SDR+ V4.15 – No Screen, No ATU


Trustpilot

This is a genuine second‑hand FLEX‑6400 SDR transceiver, supplied with the SDR+ V4.15 software update, microphone, all required cables, and original box. The FLEX‑6400 offers exceptional SDR performance, a wideband spectrum display, remote operation, and smooth integration with SmartSDR software.

This unit is the standard FLEX‑6400 model (no front screen) and does not include the internal ATU, making it ideal for operators who prefer external tuners or run resonant antennas. The radio has been fully powered and function‑checked, with all major features operating correctly. Cosmetic condition shows light signs of previous use and is supplied exactly as pictured.

A superb opportunity to own a high‑performance SDR transceiver at a second‑hand price.
