I think that when one considers the Noise floor, and the sensitivity of the three, those with a low noise location will notice the difference. Another specification I considered was ultimate filter rejection. After having experienced filter blow-by, it is one of my top considerations. I can't say that I have a superior location nor antenna setup, but I routinely hear net control stations saying that someone just faded away when I don't observe that kind of QSB here with the K3. As I hear such comments from NCSs in Kansas and Nebraska, it seems to be more than just one operator making such comments. I can't imagine the ionosphere is more stable to this location than everywhere else. 73, Nate -- "The optimist proclaims that we live in the best of all possible worlds.
