(DG) Autopilot interference on echosounder
Hi

I´am experiencing serious interference from autopilot on my echosounder. All products are Raymarine.
- Evolution autopilot w/ ACU200
- eS128 MFD with CP370 sonar module
- Transducer is B260

The interference occurs when I switch from "standby" to "auto" on my evolution autopilot. Seems to me it is the hydraulic pump which makes the noise. The noise only occurs on 200 kHz and not on 50 kHz.

I have a GRP hull. All groundings as pr installation procedures. Ferrit cores fitted without success. Also tried to mount hyd.pump on rubber pads without scccess. Also tried to change pump and ACU200 unit without success.

The technical support in Norway is a disaster. They have noe clue what so ever.
Anybody can help ?
