Hello Dave! > ...The only noticable artifact is when I power off the > rig, I hear fairly loud burst of static coming from the speaker. I also hear a slight burst of noise from the speaker at power off. If the KPA100 is not powered, then I hear a "pop" (as in snap, crackle and pop) when I turn off the K2. Now I know your K2 is doing the same, I suspect both of them are normal :-) 73, Lyle KK7P
