[Elecraft] K1 and K2 receiver performance?

[Darwin, Keith]

I know the K2 delivers contest-grade receive performance.  That is one
of the main reasons I want one so badly :-)  But what about the K1?

How does the K1 compare to the K2 as far as receive performance is
concerned?

For that matter, how does the K1 compare to other HF rigs such as my
TS-830s?

P.s.  I've tried to send this 3 or 4 times and it keeps bouncing with a
"mailbox full" message, yet I can send other messages just fine.  I'm
stumped.
