[Elecraft] K-4 features

[John Stengrevics]

Hi Wayne,

Do you have any information about:

1.  Sensitivity or noise floor of the K4 relative to the K3S?

2.  Noise blanking and noise reduction effectiveness relative to the K3S?  In the regard, will noise reduction be disabled on digital modes as does the K3S?

73,

John
