Thanks for the info, Don.
I looked at the Elecraft site - the upgrade kit seems to exist - but
I was not able to add it to a shopping cart. The crystals are
definitely there. So is the SSB kit...that's really tempting.
I should probably wait till the radio gets here. The upgrade kit
doesn't cost much, and neither do the crystals, but I'd feel really
foolish if I looked in the radio, and it was already done.

Jerry,
If you want to upgrade that K2, download the K2ATOB instructions from
the Elecraft website.
Then look at the first page to see the full list of upgrades -
download the instructions for each of them.
Armed with that documentation, you can physically examine the K2 to
see which upgrades have been installed.
Physical exam is the only way it can be done.
Elecraft still has the upgrade kits.
In addition to those upgrades, a big improvement in the IF filtering
can be accomplished by changing to the better upgraded crystals.
Elecraft sells a kit of either 7 (base K2 only) or 14 crystals (for
both the base K2 and the KSB2 adapter.

Greetings,
Name is Jerry, call KF6VB. Been a ham since 1970. For some
strange reason, my interest in amateur radio always peaks at the
bottom of the sunspot cycle. No, I don't understand it either :).
Lately, I've been playing a lot with CW & QRP radios. Got a uBITX
"kit" from India. In quotes, because it was assembled and tested, you
just mount the boards in the case. Then a "QCX+" kit from Hungary -
this was a real kit, you solder in the parts.
I discovered that I *really* like electronic QSK ( aka full-breakin
CW ). The QCX+ does it really well. But it's only one band. I built
it for 40M, but during the day, the action is mostly on 20. The uBITX
is multi-band, but does not do QSK. What to do? I investigated
converting the uBITX to full-break, but that turns out to be a very
big deal. As in "Nobody's done that yet".
...So yesterday I pulled the trigger on an Elecraft K2 on Ebay.
Waiting with bated breath for that box in the mail.
It's an early serial number - 00845. It seems that a lot of changes
took place over the years - and Elecraft doesn't show a manual for it
- their download site only shows the manual for "Rev B" PC boards.
I see that they still have some parts and accessories for this unit
- and the SSB module is not too expensive.
