There are two hardware changes that I know about. One is for the KXV3 where very strong signals on the external antenna might cause purity problems on the transmitted signal on another antenna in rare cases.
The other is an RF board modification to the AGC circuit that improves on a scenario that I noticed early on with my K3. I saw the AGC pumping while receiving a CW signal using a 800hz DSP filter setting, but heard no QRM. I found an S9 +20 db signal was about 2 khz away. Turning on the 1.0 roofing filter made the pumping disappear with no degradation of the signal I was listening to whatsoever, but Elecraft seems to want to improve this condition for those that don't have other that the stock 2.7 filter. Something will be released shortly. There are five or six SMT resistors involved and at first I chickened out on doing the mod for myself, but after the K2's I built I also built a SoftRock 40 and it has SMT in roughly the same scale so I think I can do it. After some investigation (GOOGLE), I found that there are some "Hot Air" tools for this purpose, but they are -expensive-. I expect that Elecraft owns one and would perform updates using this. But I updated my OMNI VI+ with the SSB mod (discrete components plus SMT), and made that SoftRock work, so it's just a matter of deciding whether to "ship and forget", or sit down and have a small project. All that having been said - it's very hard to find any time away from the radio, it's a real treat and an absolute joy to operate. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
