I have the older Skyview conversion harness installation. Both the pilot, and copilot mic jacks are isolated according to the plans. My headphone jacks are not. They are grounded via the mounting, without the isolator washers. In an effort to reduce interference, and while chatting with the intercom guys at Oshkosh, it was suggested that I isolate the headphone jack from the airframe, like the mic. Apparently, not using isolation washers is quite unusual in the intercom world.
As a layman, I am not sure what to do.
First, is this going to help any with noise, or should I just leave it alone??
Next, Can I just open up the hole and install the isolation washers on the headphone jacks? These washers were included in my kit!
Do I need an additional ground wire on these jacks, now that they don't have chassis ground, and If I do, do I need shielded wire, and where would they go?
Hope someone can help. This is about 3 notches above my pay-grade, and I would like to stay out of trouble here.
Thanks. Tom
