Thanks for doing this. Helped me narrow my focus from the 1000 things my radio can do to the one (S/N) that might be most important. And for 2 smart guys, you did a good job of not stepping on each other, much! 😊
Is there any plan to improve the noise reduction? e.g. NR2
You two are true experts on Flex. But, if I did not already have a Flex 3000 and figured out how to use the AGC(T) on my own to emulate how I have used the RF Gain as my audio volume control for the past 60 years, I would not have been able to follow this video other than superficially. Let me suggest that if you prepare a script as opposed to a wandering, off the cuffand stream of consciousness and have recorded examples to insert into a new taping on this topic, you will do a great service to your Flex owners/purchasers.
Per the fellow above, let me suggest that Flex would be well served to make it a priority to improve noise reduction. Yes, I understand that I have old generation Flex software/hardware - the reason why does not involve cost. Still, the DX10 I have for my portable station is more capable in noise and interference reduction. I urge Flex to consider a hybrid version of the Yaesu hybrid scheme (hybrid-hybrid?) to allow the insertion of roofing filters during challenging conditions. I suspect the military would favor improvement.
Because I like the Flex 3000/KE9NS so much in the short time I have used it (~ 1 year)I am looking at going to a 6600M/Genius for remote operation from our winter home come this next winter, but opinions of some current 6xxx owners that the NR is no better than it was on the older series gives me pause.
Cordially,

Thanks for the video.
Very good discussion, guys! I too have worked that station that you referenced. Haha. He’s in Slovenia. Love your Flex radios. Contemplating getting one. Very nice.
Mike and Tim, I got a little confused:) from what i was reading on a Flex site you want around 8-10db difference between no antenna and antenna. In you example on 40m when you left preamp at 0 it was only 4db difference! Am i missing something?
Good info, thanks for doing this.. 73
HELP lol. I have purchased a flex 3000. After install everything seemed fine but after a few minutes the audio on recieve becomes very bubbles for a few minutes then returns to normal? And help would be greatly appreciated.
0:12 "Stunning good looks?" The instant that came up on the screen I was actually just commenting out loud how ugly these radios are. They look unbalanced, boxy and cheap. Not a good look for a $5k+ radio.
So it’s a radio without knobs, what would they do to make it look better? The Maestro is a beautiful interface for the radio that has knobs and a screen and is a work of art. I don’t really see what could be done other than making the cases in different colors: Any aesthetic improvements would likely increase the cost of the radios…I’m fine with a black box
@@baldguyadventure I'm not talking about the box. The radio has a front panel, that's what I'm talking about. It is not pretty. It's clunky. It doesn't look designed, it looks like a bunch of parts from the junk box got thrown together. It has a lot of wasted space. Controls crammed together in one spot, spread all out in another. Compare it to an icom or especially yaesu front panel. Yaesu makes beautiful radios. It's the difference between a Lamborghini and a cybertruck. One is beautiful, the other looks like something a first grader would draw.
great job N6RIP
