Hi Lou
I can't get over the low noise level on the K3.
What do you make of the "mush" criticism of the rig?

lucky man, Colin. i have an s6 noise level on 80 and s4 on most of the
others. And that's on a K3. That's what comes from living right in town, I
guess. Not that I'm complaining. I have room enough for antennas and am on
the air so I'm satisfied. Although, I can't help wondering what this
receiver is really capable of.
