For the record, here's the information from Elecraft:
"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.
Since assembled -Fs and kit K3s flow through different manufacturing paths,
there is a slight variance in s/n for the phase-in.
If in doubt, check the DSP board Rev as noted above.
A picture of the Rev label location :

(The 'C', or later, revision letter at the bottom of the label is what is
important.)"
To order the mod kit, order K3DSPUPGD here:
