Jerry,
You will quickly get used to the UI. If you do not have a manual,
download one from Elecraft.
As another 'helper' one of my friends who was just getting used to the
K2 created a chart of all buttons with their functions as well as the
menu. You can download that chart from my website www.w3fpr.com. Look
near the bottom of the home page for the link to the chart. If you
print it, you can make it into a handy tri-fold that is a convenient
'accessory' to the K2.
The CW/CW-R situation is definitely associated with the BFO frequencies.
There are 4 filter widths for each mode and a BFO for upper sideband and
another for lower sideband associated with each filter.
I would wait until you have the KSB2 installed and do any upgrades that
you want before trying to align the filters and their BFOs. If you
change the RF board crystals, you will need to realign the filters and
BFOs - likewise with the addition of the KSB2 option. The KSB2 option
instructions give you some suggested settings, but you can do a lot
better by running the K2 audio into an audio spectrum analyzer running
on your computer - the visual display of the receive passband makes that
task easy.
You will need the internal counter probe if one was not included with
your K2, Elecraft does sell a kit of parts.
I can give you help with the Dial Calibration and Filter alignment.

Hello all,
My new ( to me ) K2 arrived yesterday, far in advance of when Ebay
said it would. Color me happy :). I just ordered the SSB adapter.
My first impressions: The UI is a little cryptic - a general
weakness of things with small displays and few knobs/switches/buttons,
but really not too bad. I've already got most of the buttons memorized.
Receive is nice & quiet. When I disconnect the antenna, there is
very little internal hiss. The AF gain control was scratchy at first,
but quieted right down with a little use.
Had my first QSO with it - with Don Huff, W6JL. Don gave me a good
report. Even though I was only
running 10 watts.
I notice that the band noise changes tone between "CW" and "CW R".
Could that be symptomatic of a misadjusted BFO? Also WWV is a little
off - switching from CW & CW-R changes the beat note. Looking forward
to getting into this; Ebay just yielded up a GPSDO ( GPS-disciplined
oscillator ) which is supposed to emit 10Mhz accurate to a tiny
fraction of a Hertz.
I'll want to start inspecting the radio to see what needs updating.
