How about we wait for actual actual train guys running the Base3 on their layout before we start troubleshooting problems of the Base 3?
Just a thought…

LED lights are notorious for generating RFI. Iron ferrite is used to absorb (not exactly the mechanics but makes the point) RFI. My daughter bought a string of LED lights for her room and when she turned them on it created a terrible noise on all the Amateur Radio bands. I put a ferrite core bead on the wire from the power supply to the LEDs and the noise went away. Usually it is the transformer that causes. They are made cheaply and don’t effective filter noise like they are supposed to. |

I am hoping my base 3 comes soon from Mr Muffin.

Not to highjack this thread (honest) but is there any way to deal with that? Isn't there some sort of signal suppressor you can use? I ask because in the engine that has the ground plane issue I installed an LED beacon simulator board without putting in an RF suppressor as it never occurred to me that it might be necessary. I think that I have seen these used in connection with some power supplies and to me they look like resistors. Generally I am no electrical expert but I have worried about the LED lighting modules I have used in passenger cars causing "feedback" on the track or to Legacy control boards.

I put a ferrite core bead on the wire from the power supply to the LEDs and the noise went away. Usually it is the transformer that causes. They are made cheaply and don’t effective filter noise like they are supposed to. It’s not the LED themselves that are causing the RF noise. LED is just a diode. It’s the switching DC power supplies used today to power them. Instead of a transformer to step down 120 to 5 volts 3 volts or what have you. Switching supplies do all the work. Incredibly noisy no shielding. You put one of thes supplies in a metal box and ground it problem solved but that would be hard to do

The power supplies for these cheap electronics seeing very well made. |

It sounds like you are having some serious problems with your Base-3! |
