[Elecraft] DSP Revision Question

[Dave Anderson, K4SV]

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???

Thanks in advance,
