Simrad Rudder Feedback Unit RF 300 HELP!

[islandfeverJim]

I have been through three RF 300 units in the past five years! Now I am looking at having to buy a fourth one. It is driving me crazy and Simrad tech help has been useless. We will be clipping right along under auto pilot and suddenly that dreaded message "Rudder Feedback Error" appears and unit quits working., Can anyone give any good advise. HELP!

Are they actually going bad? They produce a variable frequency centered somewhere around 4kHz (I'm guessing here) and varying either side of that by something like 20Hz (again guessing) for each degree of movement.

When you send them in, does Simrad scope them and tell you that they are indeed bad?

Rudder feedback error can also result from the clutch going bad on the drive unit, or the power not good to it. It can also be internal to the course computer itself.

If the rudder unit is indeed the problem, or if the problem is a bad circuit in the course computer and you have an N2K system, you could get the RF25 and connect it straight to the bus instead of to the course computer.
