I've been trying to track down the interference thats causing my Dynon HDX VOR needle to slowly/randomly wag up to 3 degrees back and forth without any luck.
I'm using the Archer NAV wingtip antenna tied to RG400 connected to a RAMI diplexer to an IFD440. It gets crystal clear morse code 60+ miles away and flying a localizer at almost 20 miles the needle is rock steady but the VOR wagging happens weather near or far from the station.
It doesn't make any difference with lights or strobes on or off. I've also removed power from the dynon roll servo and still no change.
I'm tempted to turn off the mags one at a time next because I'm out of ideas.
I ran across an article written by Bob Archer saying there were issue with newer glass panels and the wingtip antenna's but It didn't talk about a fix to the problem.
Anyone have this happen and come up with a fix?
