Low voltage warning
ON28:
Per an earlier question about a low voltage warning, I checked my NCE base station output and it was 14.25v, I don't want to increase it. On hard-wired layout segments the warning usually turns off soon enough, and all my LMs are up to date. I also have KAs in my locos, and I try to get a feeder to every rail except my Atlas metal frogs, which are unpowered. I guess I'll just live with it.
William Brillinger:
If you have KA's on Bridge rectifiers, your LM is only seeing 13.25v as there is a voltage drop on the bridge rectifier.

The KAs are on LM3s, so no bridge rectifiers needed.

How did you measure this? If 14.25v is the actual true (rms) output then you shouldn't be getting any low voltage warning from that figure, unless you have places around the layout with seriously high voltage loss.

I opened the base station and measured inside with a digital multimeter per this video.
