KXV3A / KXV3B modules

[Alan. G4GNX]

I purchased the KXV3A kit earlier this year, but for various reasons, I haven’t gotten round to installing it in my K3 yet!

I see references to a KXV3B kit, but can’t seem to find what the differences are and whether there’s an upgrade path from ‘A’ to ‘B’.

Looking on the Elecraft website at the orders pages, only the KXV3B appears to be on offer now. Is this because it was introduced for the K3S or for some other reason?

Hi Alan,

You can get most of your questions answered at
http://www.elecraft.com/manual/K3S-FAQ%20rev%20C5%20customer.pdf

The two main differences between the KXV3A and KXV3B are

- Availability of an additional 12m through 6m preamp.  For these
bands you would have the option (for each band) of Preamp off, Preamp
1, or Preamp 2.  Preamp 2 is on the KXV3B and is really an LNA (low
noise amp) with somewhat higher gain and lower noise figures than the
original K3's preamp (Preamp 1).

- Due to its four-layer design, the KXV3B introduces less noise than
the KXV3A.  Note that both are ultra-quiet, but the KXV3B more so.

With the proper firmware loaded on your K3, the KXV3B is a functional
replacement for the KXV3A with improvements as noted above.

The KXV3B was developed for use in the K3S and as an upgrade to the
K3.

Alan, I believe it was introduced with the K3S but
can be used in the K3. But all the "alphabet
soup", K this and K that, may have me a trifle
confused :-)
