I found that the upgraded board removed a harshness which I always thought sounded like distortion, and this in spite of my reduced hearing at those frequencies. I think it actually does some more that is not alluded to by Elecraft. My guess is that the low end change is involved in some level of distortion improvement.
Most people are very happy they did the mod. Swapping the board and sending the swapped out board back to Elecraft is really fairly easy. But don't order the board until you're ready to do the work and send the old board back promptly. The swap board is an Elecraft personnel refurbished board that someone else sent in. That allows them to run the program without making stocking decisions. 73, Guy. On Sat, Apr 9, 2011 at 5:41 PM, Fred Jensen <[email protected]> wrote: > My K3 is #642. It sounds fine on SSB.
