I think additional losses inside the K3 probably account for the higher NF. But if you're really doing weak signal work the preamp belongs at the antenna anyway.

I'm wondering how the two compare. I also wonder if maybe in the future there might be a low-NF xvtr for the K3? I like the integration idea, but I'm wondering how much of an issue the seemingly higher NF would be for weak-signal work.
