[Elecraft] Re： K3 DIY DSP Rev D - please elaborate

[Johnny Siu]

Hello Ralph,

Yes, good question.  

In fact, I really want to know:

1.  Will there be any differences in the key RX specifications (i.e. BDR and MDS, survival among strong big guns) if DSP Rev D is installed?

2.  From the bit and piece of information scattered among the emails in this forum and the Elecraft web pages, I have been given to understand that the modifications are related to the cut off point of the high end and extension of the low end of the audio specturm.  Is my understanding correct?

3.  If my understanding is correct, I suppose the TX and RX EQ in the menu of K3 can address the audio issue.  

4.  If my understanding is NOT correct, what is actual benefit of all those DSP board modification which cannot be addressed in the audio section i.e. TX and RX EQ?

I think Elecraft should set out in a table in their website comparing the before Vs after modifications in terms of performance of K3.  I agree with you that "It's really good - buy it." is not enough.  I don't mind paying the extras for the modifications but need to know precisely what I am paying for.

73 & HNY,

Johnny VR2XMC

I've asked this question before with no answer so far.
I'd like some kind of 'sales talk' so I know what I'm getting.
