With this now proven acceptable this major barrier was removed.
Again hoping that flex re consider this adaptation.
The reasons below transcend any competition or the like. It is just better for all of us
IMD. Well below any radio.
Absolute clear audio.
No intervention at any. power level
Press Auto and go straight line. functionality.
All your power placed in the band pass.
Amplifiers when sampled also a straight line solution
Absolutely reduces interference .
We are the caretakers of our bands why not reduce the interference. Why not make our transmitters a good neighbor.
There really has been a game changer in implementation. Auto functionality is today. This really means that any ham that can select the auto button can have the absolute best cleanest. signal on the band .
I am not asking or inferring for anyone to go to another radio
Remote is here. So why don't we step up and voice a yes to wanting it.
Just don't let it be me. Add your yes . Help the bands. Help yourself .
You have been beating on the drum of Adaptive Pre-Distortion (APD) for quite some time now.
Full WAN Remote is NOT here yet. It will not be here until V2.0 Software.
Full WAN Remote is far more important to far more people than APD, particularly since so few people are even aware of ADP, let alone wanting Flex to divert development resources to it...
You just need to look at the huge buzz that was generated for Flex by the release of the Limited LAN Remote feature and the Myriad of private efforts to simulate WAN Remote via VPN until Flex finishes WAN Remote. You do not see anything like that sort of buzz or interest being generated by APD...
At the Visalia DX Convention.. All eyes were on the Remote Ham Booth, the KX0 Remote head and the Flex LAN Remote. Even the Japanese were touting different forms of kludged WAN Remote...
Nobody was even talking about or showing any interest in APD.. In fact the only APD presentation I have seen in the Past Year was Warren's at Friedrichshafen.
if you looked at the recent QST, you will see that Flex already produces a pretty clean signal compared to the rest of the market.. so APD will be just a fine polishing on top of a more than acceptable product.
I would also suggest that there are many other much more important improvements such as improving contest work flow by putting spots and worked spots onto the waterfall (my personal second most important desire after Remote WAN) that clearly will generate far more sales for Flex than an esoteric improvement like APD which few people understand or want.
Clearly Flex needs to finish the very popular Remote LAN before they even consider diverting resources to other less popular projects...
I added a "like" and agree this is a feature we all (or at least most) want to have at some point. I don't think we can say remote is here yet though.
LAN remote - yes but not WAN remote.
Many folks are waiting for the WAN Remote coming in V2.0. And although I'm probably not going to use the WAN Remote feature, it's a feature many want and have prioritized ahead of other features.
So I suspect the FRS version of "pure signal" will eventually be realized, but it may be a while still. And even at that, there are many other ideas and enhancements that will be just was important to the owners and FRS.
I think as more folks get SDRs and can more easily see the benefits of a clean signal on the panadapter it will become a highly desirable attribute. Also the various reviewers are beginning to talk more about it as well. So pure signal will come to the 6000, its just a matter of time. I'm glad to know that FRS has the hooks in place on the 6000 series.

On the Anan 200D I installed a directional coupler on the output of my Acom 2000A amp. There is a -43 dB port on the coupler. I add another 20 dB of external attenuation then connect that padded signal into the Bypass port on the back of the radio.
With the new beta software NP2G is referring to, you choose auto attenuation in the linearity tab. Now while you are transmitting it will automatically adjust the internal attenuation to provide a -21 dBm signal into the ADC. It is pretty simple now.
The bigger picture is this. As others mentioned, the current state of the 6000 series has a TX IMD that is well within acceptable limits. The number of Flex radios out in the wild compared to overall number of HF radios on the air is extremely low. The impact on the bands from radios running APD is equivalent to a cup of fresh drinking water thrown into the ocean. Drinking from the ocean is still going to be very salty!
I'd rather be listening next to a Flex as it is today than a TS-520 with his processor on. There are a LOT more dirtier radios out there.
I just had a QSO with an Anan-200D with PureSignal a few minutes ago. His signal looked really great -- band edges were like a knife edge. However the Elecraft K3 and Kenwood TS-990 on the QSO *also* had good waterfall patterns. Using the incredible FFT resolution of the Flex 6300 display, if I magnified it enough the Anan looked cosmetically a little better, but the only people who could see that would be other SDR users with high-res displays.
Whether Flex implements ADP in two months vs twelve months would have virtually no difference on the bands. Most FlexRadios I see have pretty clean signals as is. The Flex 6000 user base is a small % of HF operators. So you are talking about a subset of a subset: The Flex 6000 users (as a % of total HF operators) who don't have clean signals and who would be improved by ADP. It is a further subdivided by temporal subset, since Flex will ultimately do this, so the difference months vs maybe a year or so. That is truly microscopic against overall HF volume, and definitely would not "impact the bands significantly". Given limited development resources and a higher priority list of work items I don't see a rational reason to drop something else for an early ADP implementation.
If only the straight line transmissions was the only benefit it would be great. However there are far far more advantages. Benefits. Yes far more. I listed a few but this opportunity is just great for our ham radio play
We have sdr radios. They just arn't. Just as good they are state of the mind.
Look at all the benefits. For me it is a double yes.
I'm curious about whether or not adaptive predistortion can also clean up the distance spurs several hundred kHz away, as reported by SM5BSZ for the Flex-1500 here:
But your persistent harping about ADP seems to have brought out a pretty negative reaction from this group. While I would love to be able to tinker with ADP I have to join the majority in saying that there are so many more important priorities that need to be addressed before ADP.
Bill pointed out correctly that Flex is the only manufacturer to have publicly stated that they will implement,ADP in the near future.
So perhaps you really need to expend all that positive energy working on the real major splatter offenders such as Kenwood, Yaesu and Icom... Oh...you can't can you? They don't listen to their American Customers do they?
As I own both ANAN and FLEX radios, after following both camps for some time now, I have come to the following conclusion:
Flex boys (for the most part) are appliance operators.
ANAN boys are old school hams that have a true understanding of how and why things work.
Just look at the level of posts and questions in both camps (aka forums, YahooGroups, Communities, etc.), and it will be quite evident real quick.
Some are nasty. And incorrect. It is about pure signal. A very good thing. If you do not understand the benefits please research it
We Reading some ham retort. I change it to most hams realize that we are the. Keepers of the frequencies.
Technology does not stand still. And if it is beneficial. And in the process helps everyone this is a good thing.
Since I use it. It does everything I have listed. And some good things that I have not listed
Flex has made a statement on this saying it is planed. so why does it keep coming up?
How about all the other company's who have never commented on it at all, why nothing said about them? Oh, I know this is just a Flex thing, a very slick way of bashing Flex. One thing for sure everyone pays very close attention to Flex and this community. The Anan folks are reading here every day to see what is going on. I keep getting an email from an Anan fan boy with a link to the community called an update, he must have a mailing list so everyone stays informed about Flex every move and everything writen here. So it is clear that Flex is the big game changer everyone watches.
It is true Walt. This is the area our hobby has really changed. Me for example. I do not even fully understand how everything works under the lid of the Fex Radio. I do not have the skills to take my Flex apart and fix all the components on the board. And I have never learned how to wright a program, or code.
I suppose to some then I should not be in this hobby because of my short comings in these area's.
But the technology is vastly different from Heath Kit days. I would think there are very few Flex customers that would consider repairing there Flex.
Using the name appliance operators seems to be a bad thing, but that is the state of this hobby for most. Here is a question. Lets just say, the worst thing to happen, Flex does not ever implement pure signal, what would happen, would lots sell there radio because of it, or would they keep them because they still love what it does best?
For Icom, Yeasu, Kenwood, and all the rest, I have not heard a fallout with customers saying they will sell their radios because none of those company's have not commented at all on it.
Yes I expect a few here to go over any comments I made here to find fault and debate them, I am just not into that. These are just my thoughts, time for me to move on to more important things, hey maybe radio time. what a novel idea.
All I have done is bring awareness to a great function. And as not to be forgotten
I have also tried to not answer obvious. At least obvious to me questions regarding pure signal. .
It would be far more educational for a individual to read more about it so they. Can make an educated presumption. The yes it works and works auto. And can work with flex is all there is
I did preface this conversation with a short list of some. Not all of the benefits.
It wasn't a comparison nor a just fine or a conflict. It gave you some of the benefits. Actual benefits from. Someone who now uses this system. And I have used it on other pieces of hardware.
And more and more of us will be able to hear see talk with people presently running it .
So to all a simple yes it can be beneficial. And please remember flex when you have time.
