Re: [Paparazzi-devel] Interference Problems - PPM Tapping

[Mohit Mundhra]

i tried using a very small wire of 5cm, and still the problem was same. Then I disconnected the tapped wire from the Tiny board, and the configuration was just the motor and servos directly connected to the RC receiver and the tapped wire was hanging from the receiver. Still the problem was there. 

I have tested the receiver without any tapping wire, the receiver works perfect in that case. 

What else cud be the problem??

The ppm wire is very sensitive, keep it short (< 5cm if possible) and twist the three wires together tightly.  Wrap these wires through a ferrite ring if needed.  The modem and video TX will also cause a great deal of R/C interference, keep their antennas far away and perpendicular t the R/C antenna.

I am using Futaba R156F ppm receiver with the Tiny 1.1 board. After tapping the PPM Signal from the receiver, I am able to move the servos and the throttle. But it is giving some interference problem which was not there before I have soldered the cable to the receiver for PPM signal tapping.

Is there any special cable to be used for signal tapping or is it due to some other problem ??
