[Elecraft] K2 CW filter alignment

[Sam Morgan]

Morning all,
I have a new (to me) K2 #2481 it has the KSB2 and KAF2 .
When I check the software version it reads "2.01 H   1.02" first question is:
does that mean that I am running version 2.01 or 1.02 software?

I don't yet have the dead tree version of the manual(s), so I have been spot 
reading the ones I found onlne.

I really didn't want to get into the in depth BFO alignment stuff yet and am 
hopefully assuming it's on the correct side. My question arose when I wanted to 
move the previous owners cw center frequency up from 500hz to 600hz. Using the 
instructions I found on: http://www.n0ss.net/k2_filters_using_gram_v5r17.pdf

Everything went well, the center frequency is now 600hz and the filters look and 
sound nice and tight.
Referencing page 8 of the above pdf I ran in to a problem, so it says. The DAC 
in CW Normal does is not lower than the determined center frequency value.

Then I read on page 9 and it says *if* the BFO is on the wrong side, (which the 
DAC readings would seem to indicate), one or more filter setting would show a 
shift of the center freq and be more than 200hz off. All the filter settings are 
dead on, no vfo changes needed when cycling thru the 4 settings.

SO what's the deal here, do I ignore the DAC readings?
Bandwidths used are 1400, 800, 400, 100.

128                                                   151

Ah the joys of a rig you can actually work on, heheheh.
TIA
