[Elecraft] [K3] Re： Re： K3 VS 7600 Sherwood List

[Hector Padron]

Very few of the 7600,7700 and 7800 owners will recognize that  K3 
costing  way less is equal or superior on some cases than theirs,surely
they feel embarrased to have spent so much in such those Icoms when
then we with $3K or less are doing the same job they do,I have known in
my county a couple of guys who after been using high price radios like
the ones mentioned after been comparing  them against my K3 has changed
mind and sold theirs to buy this K3,you can't hide the truth,its
there,K3 is a top performer no matter some one like or not,period.

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.
