This is my first code solution to the servo jittering. It helped reduce jittering significantly. None of the electrical solutions seemed to work.

The problem is: the servo signal drops from 1480/90 level to as low as 1410 ish periodically, causing the servo to jitter. My current solution is to read the pulse twice in 20 milliseconds after the first reading. If the second reading is below “first reading – 10”, write the first reading. If not, write the second reading. Here is the part of the code that does that:

val = digitalRead(2); //read ir
ch1p = pulseIn(5, HIGH, 25000);
Serial.print ("ch1p: ");
Serial.println(ch1p);
delay (30);
ch1p1 = pulseIn(5, HIGH, 25000);
Serial.print ("ch1p1: ");
Serial.println(ch1p1);

if (ch1p1 < ch1p-10)
{
ch1c = ch1p;
}
else
{
ch1c = ch1p1;
}


And this is the resulting readings. As you will see, whenever there is a large drop the signal is ignored.
ch1p: First reading
ch1p1: Second reading
