"I have discussed the project with others on 75, but have not demonstrated it on the air... yet! "

It will be interesting to hear how it does when Alan actually puts it on the AIr

Plus I would really like to understand how Ed Measured:

"IMD 3rd order -50 , -60 , -70DB , down." for a signal  "not demonstrated it on the air... yet! "

I actually like your comment also but for a far different reason . Trying to lessen the impact of using Pure signal WELL WELL

And on the 6500 platform .

Dont worry WAN And I,ve suggested that if you think that is sweet look at the CUDA project Another something to use as a comparison of GOOD BETTER .

I guess Its the rest of the world that wants better ,cleaner, State of the art systems

ALAN is 65 Air miles from one of my locations . And a regular QSO SORRY to disappoint you.
He has shared this accomplishment with more than me.

Measurement is easy ; Even the flex great gui gives you that opportunity. Just calibrate your display to give you the correct S9 and go from there Lets see I think Flex trusts you to do that .

AND AND if the presented real world signal is strong enough to reveal the -50 -60 or lower and so on the 3 order IMD you too can measure.

Some signals out there aren't even -20 DB The SSB ones that look like AM Is it the radio or the failure of the operator to adjust it correctly???

FYI Most of the manufacturers only use a single tone for that IMD number Yes it isn't that in the real word You weren't fooled were you Be careful when you say "it's good ."

MY 6500 on it's best day wasn't the advertised number in the real world . and still isn't
And I campaigned to have it provide that advertized proviso. And as a comparison my KX-3 is actually lower (Non Pure signal)

I also agree with the previous post it is time to stop .

(actually LOL)  Now that you mention it...

Do you think that's because (a) the Flex staff isn't constantly monitoring the forum, (b) the weekends bring out more of the "special contributors", or (c) the weekends provide the opportunity for the "regular contributors" to drink more and then post more, followed by more drinking and more posting?

I think when Tim is around he makes sure the threads keep on topic and the BS is controled before closing a thread.

Bill, one man's bull shit is another man's truth. And, btw, that cuts both ways.

By calling attention to the profanity I was hoping that the tenor would return to being professional, as most hams are. After all on the air most recoil at profanity. Was I wrong?

I wouldn't debate it either. BUT, I do agree with Burt, a lot of people consider
the words he quoted as profanity. And as such, do not add to the content of
a public discussion. I normally overlook it myself as it seems so many people
use it and make it a part of their daily language. Some folks, but not all, consider
it as a indicator of a person's language skills. (or lack there of)
Either way, it does seem, (to me and apparently to Burt as well) to take away from
the topic at hand rather than enhance it.

Good call .

Thanking or recognizing ALAN's feat is what the entire intent is period .

it directly involves a quest for improvement .


I recognized an event that those Agitating are not capable of even perceiving.


And in true human nature I strike back .


I would like to think that we all want better . and if it is not within the status quo continue the quest .
