Volkan is right. Allthough I'm very glad that you guys tune in with your knowledge, I think that most of us don't understand what you engineers are telling us. Try and keep it simple, guys. Thanks.

There are also some things I don't understand. First you make a range test with a normal PPM/FM receiver. If you are sure, that there is no interference, you switch to a PCM receiver. In my opinion, you could save yourself the extra money, and stay with the PPM receiver, What makes the PCM system better than PPM. If PCM and IPD are better, why do they still produce PPM receivers?

The fact is, that in my country, and in some of my neighbouring countries, jetplanes keep falling out of the sky with their PCM receivers locking in failsafe. I know of one guy in Germany who lost three jets last year, due to his radio going into failsafe. A few of us have always used PPM receivers, and never had any trouble with interference. How can that be?

You guys keep saying that you would never trust you xxxxx dollar jet to anything but PCM or IPD. Why? Because the more expensive receivers are supposed to be better, or what?

I want to use a good quality receiver, but I don't want to spend more money than I have to.

Also, let us know what your experiences are. Tell us some actual stories about incidents. In most cases, theory is one thing, and practice is another.
