gunrunnerjohn posted:I believe you have identified one possible issue. The DCS signal is basically a transmission line, and it uses both the hot and common rails to transmit the signal. For optimum results with DCS, the two lines should be roughly the same length as they go to the individual star distribution points.
Keep in mind that just because you are getting 10's for signal strength, that doesn't mean the DCS signal is being distributed in an optimal way. The signal strength test just measures how many dropped packets there are in the two-way conversation. You can be on the hairy edge and still get 10's.
My guess is if you properly wired the grounds to the star distribution points, you'd have better luck and less interference with the TMCC signals.
You're probably correct but since I rarely run more than one locomotive on a loop at a time I'm not too concerned about the signal loss. Plus I'm not in a hurry to crawl around under my layout rewiring.
