[Elecraft] k3 filters and kx3

[Bruce Beford]

Technically true, Terry. I perhaps oversimplified my response to the 
inquiry. "Baseband" can mean different things to different people. 
However, the answer to the question remains correct. - "No, you cannot 
use the K3 filters in the KX3." I will leave further amplification to 
Wayne or Eric.
