Rev C => Rev D may have been component changes only. I believe Rev D changed the LPF corner frequency. The board fab level is likely the same, Rev C. That', or Rev C board fabs are compatible with Rev D assembly changes.
Normally (not sure on Elecraft's 'normal') a paper label is placed over silk assembly rev label to indicate a change in components. Matt Zilmer Consultant W. 909.394.6052 C. 909.730.6552 E.

Arrow Hwy, San Dimas, CA. 91773 Pecca Fortiter -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Dave Anderson, K4SV Sent: Tuesday, March 05, 2013 8:09 AM To: Elecraft Subject: [Elecraft] DSP Revision Question Hi All, I was reading the DSP upgrade docs and am under the impression that all new Main DSP PCBs being shipped are to be Rev D I just completed assembly of SN6855 and noticed that my brand new main DSP PCB reads Revision C on the silk screen. It appears according to the upgrade link here http://www.elecraft.com/K3/mods/dsp_rev_c_information.htm a sticker and or some PCB modifications are to be done to older PCBs. During close inspection I was unable to find a sticker like the one pictured on the Rev B PCB in the docs. I found other square stickers with plenty of numbers and letters but nothing showing clearly a D on it. So this leads me to ask, How is a Revision C PCB being modified to be a Revision D? I see no cuts and jumps, no small PCBs, no added parts, nothing out of the ordinary. So do I have a Revision C or D DSP???
