[Elecraft] K3 Rev C DSP with Low Freq Enhancement ship date info; New swap out option on parts order page. CORRECTION

[Eric Swartz - WA6HHQ, Elecraft]

CORRECTION - I have some egg on my face. I misread our internal release 
date notes for the Rev C DSP board. Here is the correct Date and S/N 
Information:

We started shipping the latest DSP boards, Rev C, approximately May 1st, 
2009. 
Any K3 DSP board Rev C or later will have the extended low end audio 
response enhancement.

This corresponds approximately to K3 serial number 3018, plus or minus 
10-20. 

The complete upgrade info page has also been updated with this information:

I apologize for any confusion this created.
