Subject: RE: AeroElectric-List: noise problem on radio


Thank you Bob, 
I went back and inspired by your comment about Mr. Clue, I carefully
observed the phenomenon without jumping to conclusions.  It turns out the
interference only happens when the (Trio Avionics Pro Pilot) Autopilot is
ON, even if the engine is OFF.    Attached is a link to a video with sound.
There is a lot of background noise (mostly the sound of the GNS430 fan) but
you can still here the interference and see that it completely disappears
when the AP is turned off.
The interference happens in the form of a RX signal on the radio.  In other
words, whatever is happening is causing the COM radio to think it's
receiving a transmission, as is evidenced by the RX signal that's visible on
the GNS430 screen.    
Anyone have any idea why this might be happening?  I guess my next step is
to see if this also happens on, say, a handheld COM.

Subject: AeroElectric-List: Insulating 3.5mm Jacks
From: Jared Yates <email@jaredyates.com>

Has anyone found an elegant way to electrically isolate 3.5mm audio jacks?
 I don't know if it is as necessary to isolate these as we do the full-size
headset jacks, but does anyone make isolating washers for the smaller guys?
