Bill and All, I think you hit the nail on the head Bill! Johnny seems to be very nicely equipped over there, and certainly should be proud of the choices he has there in his shack. However, if you aren't much interested in CW, a great deal of the refinement of the K3 can be pretty subtle. I suppose if I only operated SSB, I might be just as happy with a 7600, 7700 or 7800--maybe even happier in some respects. There are several operating conveniences the Icoms have which the K3 really doesn't effectively compete with. Even on CW this can be the case, unless you are really in a battle with QRM. Nonetheless, I'm still extremely impressed that I can pretty much stand toe to toe with the Icoms, save several thousands dollars, and still have a rig I can pick up with one hand--two fingers actually, if I grab the handle. Not everyone sees it that way though, and I understand their side of the comparison. It's just a matter of what your "hot buttons" are.
