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. 73, matt zilmer W6NIA On Fri, 10 Jul 2015 23:45:10 +0100, you wrote: >I purchased the KXV3A kit earlier this year, but for various reasons, I >havent gotten round to installing it in my K3 yet! > >I see references to a KXV3B kit, but cant seem to find what the differences >are and whether theres 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.
