Are there any great hardware differences between a 500 serial number and one
of the latest production batch?
I missed the news on a new DSP board also. I have K3 #101. Is this
something I should be looking at?

We started shipping the current DSP boards, Rev C, approximately March

Any K3 DSP board Rev C or later will have the extended low end audio
frequency response h/w enhancement.
This corresponds approximately to K3 serial number 2800, plus or minus
10-20. Since assembled -Fs and kit
Thanks for re-posting the info. I am just not sure how much of a
difference this makes to those of us who aren't too concerned about hi-fi
audio.
If I'm listening to a CW note at 700hz, or normal SSB, can what's below
300hz really matter?

Hmmm, no mention of the (hardware) AF low pass filter in the
announcement quoted below... can Elecraft confirm/deny? There is no
documentation of the K3DSPUPGD option on the order page, and nothing
in the K3 Alerts, Enhancements and Application Notes page either.

Jim,
Replacing the DSP board isn't that difficult; remove the front panel, and
you'll see the DSP board attached to the rear of the FP via a couple of
stand-offs and some screws. If you take your time, it could be done in
