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 prior to the ADC and DSP, and not at baseband audio frequencies, else it would not be roofing filter, but merely a post audio filter.
Terry K4RX 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.
