I'm lurking this list to gain a feel for the K3. As it seems to be the hot item these days, it's growing (glowing?) reputation makes it worth looking into.
Recently, a thread took place on eHam (I know, I know...) about an op's issue with another DSP based rig and high levels of QRN. A comment in the thread from another op leaves the impression that his K3 also has the same response to high levels of QRN, a sort of reverb as he described it. Here is the thread in question: http://www.eham.net/articles/23975 My main desk rig is an FT-920 that I've had for over ten years and its DSP functions have seemed to help a lot with reducing the effect of QRN and I've not noticed what was described by the poster. As a K3 would necessarily replace the '920, I certainly would not want to take a step backward especially since QRN is common with 75m nets during the summer. My questions are twofold. First, is the "reverb" common or is it just certain ops who notice it? Second, from my research I know that the K3 is heavily DSP based, but also has provisions for IF filtering. Can te DSP essentially be "turned off" or otherwise disabled so that it functions as an analog rig which posters in that thread claimed as superior. Perhaps this is much to do about nothing. Don't get me wrong, I'm quite impressed by the various videos I've watched of the K3 in action which is the closest I can get to operating one before I buy. The numbers and the reviews look very good and I'm considering purchasing one later in the year. The QRN issue with DSP took me a bit by surprise which is why I'm asking.
