That is what the K4 FAQ says: K4HD is equivalent to a K3S.

I asked a similar question at the Elecraft K4 Forum at the Huntsville
Hamfest this year and came away with the impression that the K4HD would
be required to meet or exceed the performance of the K3/K3s in this regard.
Since Eric, Wa6HHQ presented the forum and answered my question, he can
correct me if I came away with the wrong impression.

This doesn't answer my question. Is the K4HD required to provide nearby
signal blocking equal to or better than the K3s? There is no statement
like this in the FAQ, nor any technical specs. I'm sure Elecraft has run
these tests, and I hope they'll share them, or at least give us some idea
of the relative performance of the various K4 models compared to the
K3S as
regards to nearby signal rejection.

Read the FAQ. The K4HD is a K4D with a superheat front end with roofing
filters added in front of the ADCs. Like adding a K3 in front of the
SDR.

Can somebody tell me which of the K4 models will produce better
blocking
of extremely strong (S9+20 to S9+40) nearby in frequency signals
than a
K3S? Is this blocking gain compression? I'm trying to plan a future
station upgrade and I have ham neighbors.
