Thanks to AC7AC, K2VCO & W6NIA for your responses.
Last time I asked, somebody suggested you can just
crank down the receiver's bandwidth & that should
suffice. Not living next to one of these things at the
bottom of the solar cycle must be nice.
Out here, it's often only the transition to the stopband of
the OTHR that is less than S-meter pegging. On 40m,
there is 200+ kc of S-meter pegging b'cast in your face,
too. Probably the only more extreme environment is faced
by those poor 5B4s within spitting distance of Akrotiri.
It is how well the K3's NB works in those situations that
is of interest. I believe, just like how what 10m has
become in SE Asia only became a concern to the rest
of the world when conditions returned, in time the importance
of the NB will become evident in Elecraft's domestic
market. Hopefully they got it right - so far it's hard to tell,
but it seems during development & apparently so far no
customer has had an opportunity to try one in such an
environment, as it does not exist in NA.
Perhaps with K3s arriving in UK, one of the Gs will take one
on holiday to 5B & have a go.
