That's an interesting theory Matt. I don't know if you ever noticed, but on the entire lower level, I have installed .1u capacitors at all the gaps. Those are specifically to allow the signal through, without actually "polluting" the rail with ground, so it can still be used for detection.
Of course, it was the upper deck where all the chaos occurred. I never installed the caps, because things were running very well under TMCC. That's a big project to go back and solder up all those caps. I'm hoping the solution lies elsewhere.
