Not true! The conduit should be an excellent radiator for the airborne signal as long as it is earth-grounded.
Again, please use your ohmmeter to measure between the U-ground or conduit and the wire that feeds the TMCC signal to your layout. This should be an open circuit, i.e. near infinite resistance.
I will Dale. That and the radio test. Since we went through this exercise a little more than three years ago, much has changed. I now have a nice digital meter that I can read and trust, and the layout has more than double the amount of live track that it had back then.
Since most of the trouble is on the main level, and a number of ground buses have been added there, I'm pretty convinced that with a little strategic cutting I may be able to clean things up. I'm leaning toward this conclusion based on the wiring on the upper level and the relatively trouble free TMCC signal there. That ground bus simply follows the track all the way around, no branches, no loops, just one very long wire. I also need to look at the wire that connects to the base, and how it enters the ground wire network.
