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,
Doc - K8DO
Is there any plan to improve the noise reduction? e.g. NR2
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.
Thanks for the video.
Good info, thanks for doing this.. 73
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?
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.
great job N6RIP
