Tom/N0SS described 14 years ago a simple technique that makes a filter board change when the KAT1 is installed much easier. He cut two segments from a thin rubber band and placed them inside the spacers that separate the KAT1 and KFL1. He threaded the screw coming out below the KAT1 PCB into each spacer with rubber strip in it. That keeps the otherwise loose spacers in place on the screw threads as the screws are turned during KAT1 removal/replacement for subsequent KFL1 swaps. The K1 MCU remembers the frequency display calibration for each band that was set by OFS, using a new KFL1 requires only loosening the two KAT1 PCB screws, removing the KAT1 (the KAT1-KFL1 spacers will now remain on the screw threads as the KAT1 is pulled off), swapping the KFL1, replacing the KAT1, installing the K1 top cover, and assigning b1 and b2 to the new bands. OK...so it's *still* a bit of a pain. But not having to mess with those two PCB spacers below the KAT1 is *major* improvement!
