Sam,
Do not ignore the DAC values, they are all on the high side of the
carrier which indicates that they are on the wrong sideband - as you
have it now, you will transmit 1.2 kHz (double your sidetone pitch) away
from your received frequency! You may enter those values into the CWr
filters, because they should be on the high side of the filter center.
Setup with Spectrogram again and turn the vfo knob so the DAC values go
lower. You will see the passband go lower on the screen and then will
reappear and then go higher in frequency again - you just shifted to the
opposite sideband. When the passband is positioned more or less like it
was initially, that is the correct setting.

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.
Center freq DAO CW Normal DAO
142 157
135 154
130 152
128 151
Ah the joys of a rig you can actually work on, heheheh.
TIA
