No, the KX3 roofing filter module is completely different. It works at
baseband frequencies, rather than the 8+ MHz IF that the K3 uses. You will
not be able to use K3 filters in the KX3.

The Elecraft KX3 architects should weigh in on this topic - a simplified
block diagram would be helpful. The KX3 roofing filter is likely a analogue
filter realized with precision op amps and operating at the KX3
low-frequency IF (11 KHz?) - not baseband. The roofing filter is applied

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.
