When I built the K2 RF board, I looked for guidance about which XTALs to ground on the side. It looks like the BFO reference XTAL needs to be grounded on the side, even though I didn't pick that up before.

I moved the ground wire from the top of X1 to the side, as the KDSP2 manual says it should be. As I've already done it to the main filter and the KSB2's filter, that leaves X4 and its sibling, the first IF filter, grounded on the top. I dunno if I should ground them on the side or not.
