Hi Jim, I have an older K3 with new SYN boards. I also have the 500Hz and 200Hz filter. I just tested it on CW and I can hear a very faint pop when turning the bandwidth knob. As you noted, it seems to be present only at the narrow settings. I start to hear it when changing from 350 to 300 and below. It's loudest when changing from 150 to 100.
Having said that, it's faint to the point that I can't be sure if it was there before the SYN changeover or not. It certainly doesn't bother me even with high audio levels. 73, Mike K2MK Jim Bolit wrote > I just got my K3 back from Elecraft.
