FlexRadio 8400M w/ ATU

Jim Moore

This FlexRadio 8400M ticks all the boxes … great radio, great software, great price and great warranty.  

I upgraded from a 6400M, and the transition was interesting, to say the least.  The 8400M is a more stable, more robust rig.  Mine has FlexRadio’s SmartSDR 4.19 installed, and is ready to upgrade to 4.20.  SmartSDR+ is good until mid-November 2026. This radio’s serial number begins with ‘4325,’ and with the transferrable warranty I’ve purchased, it’s covered by FlexRadio’s two-year factory warranty until early November 2027.  I’ve owned it since November 2025, and performance has been flawless.  There are no modifications, no scratches, no scuffs, no stories, and my shack is nonsmoking.   

I’m moving to a remote operation with a different setup.  The 8400M ships to the new owner in the original Flex shipping carton with blue IT cable, Anderson Powerpole power cable, GPS antenna, Flex FHM-3 microphone and Quick Start Guide.  Also included is the embroidered dust cover I purchased before I received the radio.  I have only used the radio for SSB and CW … no digital modes.  This 8400M is about as pristine as you can get, and you’re saving several hundred dollars off Flex retail.  

I’ve done a factory reset, so your ownership experience will be akin to a full-fledged Flex retail purchaser.  Radio is in perfect working order, but is sold as-is with no returns for the usual reasons.  $340

$3400 shipped CONUS via insured UPS or FedEx Ground.  Because I’m insuring the package for the entire sale value, I’ll have to schedule a pickup and that may take a day or so to arrange.  Reach me via email for the quickest response:  My callsign at Yahoo.com.  Thanks for looking and 73
