I have come up with what I think is a better mod for grounding the mike connector (J2) on the Front Panel board. The two standoffs were removed on each side of the mike connector. The two lockwashers on each standoff were removed. Two small expansion springs (about 1/2" X 3/16" before expansion with the last loop on each side lying flat to accept screw) were purchased at the hardware store. I placed the two springs on one screw securing them with the standoff, routed them on each side of J2, and joined them on the other standoff. These standoffs are at ground potential. I did not replace the two lockwashers on each standoff. This mod seems to make a good ground. Hopefully, this along with good grounding and well sanded panel connections will help eliminate loss of audio due to ESD zaps to K2/100s with the KDSP2 installed. Roy Morris W4WFB
