The LA3ZA Unofficial Guide to Elecraft K2 Modifications is an excellent
resource for determining the mods that exist for the K2.  What I find
confusing however, is where some of the upgrades incorporate or include
other mods.  For example, I understand that the KPA-100 includes some of the
Revision B mods.  In short, I am more than a little confused in this regard.

I am planning on upgrading my K2, serial # 2359 [firmware 2.01H] with the
KPA-100 and KDSP2.  It has the KSB2 and also the KIO2 (which I understand is
superseded by some arrangement in the KPA-100).  At the same time, I would
like to install the Revision B and firmware upgrade, and perhaps the wider
SSB crystals.

I realize that it has become hard to distinguish the various mods from each
other and their status vs serial numbers etc. That's why I have subdivided
the Mods page into pre- and post-rev B mods (serial no #3000). Also, the
various categories in the main list (K2, KSB2, KPA100, ...) start with the
mods that have been included in the K2/option at various serial numbers and
dates, and if possible the subsequent mods in the list are those that have
been designed by Elecraft. Probably this system is not quite consistent
throughout the lists, but it is the general guideline.

Regarding #2359 and KPA100: I have #2159 and just recently added the KPA100.
The KPA100 comes with all the required firmware upgrades so there is no need
to buy that separately, and the only rev B mods kit that is included is the
"10M BPF, VFO/ALC Mod Kit for the K2". I believe this is the only one that
is really required to run the KPA100 also, so all the other rev B upgrades
can be taken at your own pace, either before or after the KPA100.
