With this now proven acceptable this major barrier was removed.
Again hoping that flex re consider this adaptation.
It is a successful. Auto selectable function that the components are already accounted for in the flex that any and all software that accomplishes this is open source. Easy to review easier to make your own
This isn't re inventing the wheel. It will do exactly as i and other have found out. .
Since I am not advocating. Any hardware switch. If you want these benefits you gotta keep asking . And allowing everyone to read see hear. Look at the difference. .
So you only get it if you want it .
This function has been promised since 2009. Yep.
And without pure signal no matter how you tell the story not having pure signal and pressing the on button it cannot. Get this clear cannot match any of the listed benefits. Not almost not pretty close nope
If you see these traits available. Stop the excuses.
It's not about. "It's great now".
This adaptation. Assists functions that cannot be presently duplicated
And The present program. Open source program can be looked at. It can be a educational event that would allow any else to write their own. Not copy .
And I no longer want or ask for any flex promise. It should be implemented. They know it. They know the benefits and if flex users see this as a improvement or a value added process to should be there for flex users
So I am asking if you like the idea just say yes. Learn about what benefits you can get.
Warren has been working on pure signal since 2006 as I understand it. It's one of his projects and apparently it's your passion. It's not my passion in any way and from what I read it's not much of a passion for every one else. I'm interested in other stuff. If pure signal comes along whoop de doo I'll give it a whirl. One thing pure signal will do is add lag to the signal stream. Maybe I don't want lag in my signal stream. Maybe I like the dead bang perfect monitor function which has 10ms lag that Flex now provides, some of the best in the business. Maybe I don't want the extra complexity. Maybe Flex needs to take the time to understand how the extra complexity effects every other system before they implement it, and maybe fix what pure signal will break. How will pure signal effect the QSK CW if it adds lag to the signal processing? How does that effect digital modes? How does that effect remote operation? How will that effect WAN operation? The 6000 series is a more complicated and feature rich radio than the Anan system, more moving parts more things to break.
You haven't even told us how pure signal effects these kind of parameters in the Anan, mostly because you don't know. In fact you haven't even told us how pure signal works. What are the hardware requirements across all of the Anan platforms. What is the additional expense. How do you have to modify the radio? Maybe we don't want added expense. Maybe we don't want to destroy the resale value of the radios by doing non factory sanctioned modifications. The only thing you have told us is pure signal in your opinion has some benefits, and now after 9 years it's automatic. The benefits are there but they are not dramatic. A few extra dB of IMD in a land of speech processors is not dramatic and perhaps is not even worth the trouble or maybe the cost is more in terms of performance is more than I'm willing to spend. In terms of "splatter" the addition of the W9GR processor has gone a LONG way in improving that situation. I have heard some interesting effects with pure signal in terms of improvement of intelligibility in very weak signals when pure signal is engaged. The added coherence seems to provide a better S/N at the receiving end at least when using a Flex as the RX, so it is definitely worth studying, but I'm not sure if that benefit is universal or not. Phasing radios have always sounded better than heterodyne radios, and phasing to phasing may be better still. Bears some understanding.
That being said I am interested in adaptive predistortion. Adaptive predistortion for example could be used to subtract noise, theoretically even static out of a received signal path and may give some ability to hear under the noise, MAYBE big MAYBE I don't want anyone to think this is a PROMISE. I don't work for Flex and I can't promise anything. This is kind of what science lab is about. Taking the time to understand the processes, the system and the system limitations and the performance hit these kind of processes will cause, and writing some code to effect what you learn. I'm 100% in favor of that because that is where the boundary will be pushed. I know for a fact Flex is engaged but I do not know where they are going with it, nor is it my business to know. What they learn while investigating one aspect of signal processing may have direct benefit on another, so I'm willing to trust the process. So far the process hasn't let me down because the radio is a far better radio than it was a year ago.
Now Ed I fully expect your next note will be no different than your previous 20 which is why I think this is all a manipulation.
Pure signal good
Pure signal now automatic
Yes we heard it the first 20 times. We agree
Pure signal good
Pure signal automatic
We just don't know if Anan's implementation of pure signal is worth the cost and if it's done in a way that won't hose up other things in the Flex radios.
You're kind of like a used car salesman Buy this wreck. You know you NEED a car even though the one you have works fine. Buy this wreck. Babies are starving over seas. Buy this wreck. Stop procrastinating. Get out the checkbook. Buy this wreck. See it's got a hickey on the hood!! Buy this wreck. You promised!! Buy this wreck.

Does he think Gerald promised?. Even if he did, Gerald can change his mind, it's their product and do what they want.
How can pure signal be incorporated in the Flex? Without Flex involvement?
Is he asking every one to put the heat on Flex and demand it?
He said this was all intended to be just an FYI, ok we got it thanks.
Here is Gerald's last post on this subject, I see no mention of promising anything and no date mentioned. This post of Gerald should clear everything up. If it doesn't, go away.....
Periodically the topic of Adaptive Predistortion comes up for discussion on this community. Our team has been consistent in our position on this subject but sometimes it is useful to restate what has been said many times before in the interest of clarity. Here is a restatement of the facts:
The FLEX-6000 Series hardware has the necessary connections and internal RF port to port isolation to support adaptive predistortion software. We have verified that transmitter output to receiver input isolation (e.g. ANT1 to RXA) is >80 dB on all bands including 6m, which is more than ample to accommodate adaptive predistortion using an external amplifier in the loop.
FlexRadio remains interested in adaptive predistortion technology but we have not in the past nor will we now make a time frame commitment. Our internal engineering resources are 100% allocated to complete our published road map for v1.x releases through v2.0. We believe that the features committed in those releases are currently of higher priority to the vast majority of our customers than is adaptive predistortion.
- We periodically review and rank our software backlog and feature requests. We look at the ranked priorities and compare the development magnitude for each feature to the available engineering resources within a release cycle. Based on those factors, we make decisions on what features make the cut in the release planning process. So far adaptive predistortion has not made the cut. That doesn't mean it won’t make the cut in a future release.

I have played with ADP and heard Warren speak at Friedrichshafen
... yes the benefits are there but frankly they are not significant enough to make that much difference except for a few isolated situations such as the other guy discerning information from your very weak signal (unlikely in a contest or DX pileup) and the Audio Purists...
For the rest of the ham world ADP is a big Yawn....
Definitely not enough benefit in terms of increased sales from ADP for new Flex Hardware for them to divert resources at this time from much more important projects like 1.5 Noise Reduction or V2 WAN which will increase sales...
Anyways Flex 6000 series is already at the top of the list for clean radios.. so you should be harping at the real offenders from Japan not Flex....
I live in California.. the home of Tree Huggers...we have all silly sorts of rules that cause us to waste money on Tree Hugger things that have little or no real benefit...
Cleaning up spectrum below -50dBc by one small vendor seems to fall into the category of Spectrum Tree Hugger.... It sounds good and socially responsible on paper but in the real world it will cost time, $$ and resources to produce and the net benefit will much such little difference that it likely will be unmeasurable....
Sort of like why we are forced to pay $1 more per gallon to have Summer Blend gasoline to "protect" the environment in California.. that only causes more pollution because we get much poorer gas mileage and use more gasoline...but the Tree Huggers feel good....
Frankly you have said your piece.. everyone agrees that it would be "NICE" to have ADP...
But clearly you were NOT listening.. when everyone including Flex also said that its on the list AFTER much more important and beneficial features are first implemented...
So rather than harping on the "Nice" Tree Hugger Part
Prove Me Wrong......Why don't you make a business case to show how many units and $$ in increase sales will result from ADP for Flex. I am sure that if there were money to be made Flex would move it up in priority.
Money talks BS walks...
