|
|
I'm building my panel, and have it to the point where I'm checking
things out on the bench (outside the a/c). Yesterday when checking the
audio/Com/Nav functions I noticed noise coming through both the pilot &
co-pilot headsets. I believe that the source/s of the noise
(antagonist?) are the cooling fans that are internal to the EFIS/MFD
systems that I have installed, as the noise is only present when these
systems are powered on, and the noise changes , i.e. becomes additive
when both systems are powered on. (It reminds me of flying the Baron
with the props unsync'd). I'd appreciate any insight on how to trouble
shoot this one. The Audio panel is a Garmin 340, all connections/wiring
is with shielded wires w/shields grounded to the back of the rack per
Garmins instructions.
