PPM encoder and noise issue

Posted by James Rodgers on April 5, 2011 at 6:41am

I am having a hell of a time with my PPM encoder. When I plug it into my RX it creates so many problems that it just can't be used. It makes all my servos jitter badly to the point that I can even go 300 meters before I have complete lockouts. 

 

In this video I have the RX not to far away. I have tested with another RX, Ubec, Linear bec, and servos, locations ... everything I could think of. How do I fix this problem? I do notice that the RX light starts flashing when I plug it in and when I plug it is slot three it all go dead (kills the signal completely).

I have a feeling I have a faulty unit

    Hey James,

    Have you tried running just the signal wires from APM to the receiver yet? Let us know what you find when that is the case.

    Sounds like a faulty unit or a soldering error. We've had no other reports of problems and my units don't show any issues like this.
