[Elecraft] DIY DSP Rev D

[The Smiths]

In that case I would rather see someone keep re-posting Eric's/ Wayne's posts than try to answer the persons questions themselves.  It just keep bringing up more questions and more e-mails asking the same thing and for more "proof".  I can read the same answer from Eric and Wayne 100 times before I want to see the "telephone game" played on the reflector with everyone answer with their "idea" on why the original post said.

My guess is that both Eric and Wayne are tired of restating answers for people who are too lazy or thoughtless to check the archives for the answers they've already given.    Don apparently has more time and patience.

Why is Don, or any other person other than Eric or Wayne answering this simple question? Both can make ONE simple statement that tells the enquiring people everything they need to know.  I'm tired of all this conjecture, when the answer should simply be told by the very company that knows what's going on.   No offence Don...

Thank you for your intended help, but certainly I think that the people asking the questions, knowing full well both Eric and Wayne monitor this board, can clear this up themselves.  Then I can get back to reading my daily email without the 400 e-mails about the same question over and over again.  Thank you.  

And now, if you will, Wayne....

David,

Yes, Wayne, Lyle and Eric have stated that the results were quite 
similar to the W9AC mods, but were done in a different manner (I presume 
it was easier to accomplish resistor changes in board manufacturing). 
There may have been some other insignificant 'tweaks' to the hardware 
done at the same time (just because it was convenient). But there are 
no functional or performance enhancements associated with those changes.
I would think if Elecraft had made improvements, they want to advertise 
that fact, a better K3 should sell better. 

Some of these questions are beginning to sound as though there is some 
"conspiracy" going on. The fact that a board level B can be upgraded to 
assembly level D (with the component changes and the LPF) says that the 
board printed traces has not changed. Note that the board level relates 
only to the printed traces, solder pads, etc. The assembly level can be 
quite different.
>From the information that we have, the original board was assembly B 
(same as the board level), then the low frequency response was extended 
resulting in level C - finally, Eric decided to add the LPF since it was 
available, resulting in assembly level D.

I would gladly fit this daughter board and perhaps do the LF enhancement, 
but several on this list seem to be saying that the exchange DSP board does 
something more than these mods provide.

Can anyone clarify?
