    The first 10 days with my "baby", a new Flex Radio 6400 was not completely what I expected.


    First, with excitement on getting a text message alert that my package was "OUT FOR DELIVERY" I moved two of my security camera's to watch for the BIG BROWN TRUCK. I live in a gated community and with new drivers they do not know to access the code for entry. The camera's would allow me to see the street towards the gate and the back one would see the outside area of the gate. At 2:14pm the magic happened and the big brown truck stopped at my door.

    Opening the package to get this baby wired and online was the first business at hand. Took all of 10 minutes!
    Watching it boot up the first time and connecting SmartSDR from my PC was a fantastic experience. It is alive!

    I spent the next hour learning and setting up a few of the limitless options and adjusting my new HyperX (red) USB mic so it sounded the way I wanted for different profile. Next was wiring the Elecraft KPA500 AMP and KAT500 Auto Tuner for full tracking. This was to easy.


    I made the first contact to a IOWA station from my Tucson AZ QTH. I called CQ on 20 meters and he came back after the first call. He said wow what are you using at your station the audio sounds fantastic. I told him it was my first contact with the Flex Radio 6400. He gave endless praise and this was the start of many more reports stating the same.

    That first night on a 40m net I attend every night with around 90 listed members was my most contacts on this net. It seemed everyone wanted to call and my reports were the best I have ever received. Again audio was stated over and over that I have never sounded so good in the past.


    The next day I installed the SmartSDR iOS on my iphone and ipad before heading out with my wife for some shopping. I waited in the car while she did some shopping to experience remote operations on the device you have with you all the time. After launching the app and the screen coming to life, hearing and seeing my home station blew my mind. I could not believe it to be real. It was perfect.

    I watched the waterfall as it displayed active stations and with a simple touch and swipe I was tuning from station to station with perfect control. There was a station in Texas calling CQ so I hit the PTT button and placed my first mobile call to him. He answered me on my first call and we started a 20 minute QSO while receiving a great report both S9 and unreal audio. He even asked me to text him a screen shot as he could not believe I was mobile on an iPhone. The user experience is a real eye opener for sure with SmartSDR for iOS.


    When switching from a radio with knobs and dials that I have used for many years seems a bit strange but after the first few days of operations you will be wondering why you did not move to the future sooner. The SmartSDR offers so many features after 10 days I am still finding crazy good things this radio does while some other radios might offer these functions, its the easy way you see and access, use these features.

    On my old radio, I turn on, tune to some freq and that was about it. Not the case with Flex Radio as you "SEE" what is going on in detail. The one biggest enjoyments using this radio is noise control. This is were it really shines. You have so many options to drop the noise to almost "ZERO" while hearing stations you would have never been able to hear before. With the band conditions being so bad, this radio can bring joy back to your shack.


    My experience over the first 10 days has been a true unreal almost unbelievable experience. I hope others have a chance to touch, see and play with this future feeling technology. Its out of this world!

    Very nice. No doubt that SDR platforms are the wave of the future, especially the embedded ones. Who would have imagined even just a few years ago that you would be able to access and use your ham radio gear from a small device and from virtually anywhere? I've been lucky enough to have experienced both radio worlds new & old and it never fails to amaze me when I look backward, present and forward on Radio Road ;) :)

    P.S. - Your first 3 pictures are of advertising quality - you should offer them to Flex Radio :)

    Thanks Steven for taking the time to post this. I'm shopping for a new rig and have been giving Flex strong consideration. This post was very helpful!

    Curious why you selected the 6400 versus other models? Thanks in advance for your feedback.

    What on earth did amateur radio do before computers and the Internet? I can't imagine.

    I am glad you like the radio, but this is NOT a REVIEW. You are just bragging about your new rig. Now, that is OK, and I am not jealous or dissing the rig, as everyone should be as excited and as exuberant with his new rig as you are. But, you should not market this post as a "review," as it is merely a comment after an un-boxing lacking any technical information beyond the fact it works as you expect. Moreover, the fact you live in a gated community is irrelevant to using the radio. And, it is possible your first contacts were so good only because the other station has a huge yagi or log periodic with 20 dB gain atop a 75 foot tower in a quiet rural setting doing the heavy lifting in both directions.

    I am truly pleased you like the rig, but this is not a product review. Enjoy your new rig.

    Just MY take. K8JHR
