Recently, I have noticed the CDI needle to shake and dance on an ils approach with up to 1 dot deflection getting worse as the runway nears. This is a new problem in my rv8 with dual skyviews and garmin gtn 650. The autopilot has also had difficulty tracking the ils course. I believe these problems are related. Antenna? I cleaned antennas but problem persists.
The GPS approaches are perfect in autopilot mode with no hsi cdi needle dancing. Any thoughts?
Thanks
