ok, you edited the question and it is now within my understanding. With the PCM receiver the baseline was 12 steps, while previously on all airplanes it was a miniumum of 50 to 55 paces. With PPM, last night simply placing the transmitter on a table maybe 20 feet from the airplane with an 8103 transmitter ant. down, I was getting servo jitter in the airplane with the ant. in some positions but not all positions. Then I started the test by placing a receiver and a servo all over the airplane to help determine where the noise was coming from. Tonight I will start removing items from my control panel to see when the noise goes away.

Sean..... Baseline range check distance is established with all turbine / extra on-board equipment unplugged. Nothing being checked but the radio alone. 12 steps can't be!!!!!! You should be able to walk your with transmitter.... (antenna removed)... about 300 feet away from your airplane and still have normal control of all radio channels. 225 feet minimum...... if you can't get 225 feet away doing just the Baseline check you first need to send the transmitter module and receiver in for tuning!!
If you can't establish a baseline you'll never be able to have any distances to compare with i.e. "Baseline"
Remember all range checks should be done with your airplane mounted 3 feet up off the ground on a wood or plastic holder. Also at the 300 ft range you should be able to turn the transmitter in all directions and be "hold" or fail-safe free. Best thing to do is set the Elev. to full up fail-safe so you know exactly when you are seeing the limits of your range.
