[Elecraft] K3 Sub-receiver

[Paul Christensen]

I just read Wayne's 1/16 update concerning progress made toward the release 
of the K3 sub-receiver where he states in part:

"Isolation between the receivers is critical to usability. For example, if 
you're listening to an extremely strong signal on one receiver, none of it 
should leak into the other's I.F. After extensive testing, we concluded that 
we were close, but needed more isolation."

Knowing that Wayne & Eric are immersed in the product launch, does anyone 
know if the forthcoming KRX3 change will require existing K3 transceivers to 
be modified?   Or, is the isolation issue wholly determined by the 
sub-receiver module and not the main receiver?

My apologies if this topic was already covered but I did not see this point 
covered in the archives and boy was there a lot to filter after the 
announcement.  Tnx!
