Hi Reinhard,
I can probably test with a local friend, however I have tested it with several decoders, and none give me good slow speed performance, which is what I want from it. I think I will dismantle the drive train once more to have a good look, check for RF surpression RC circuits, and if all else fails, get another decoder to try. (I have tried the decoders in other locos and after setting up, they do work fairly well).
Gus, yes BEMF can be disabled on the T4X. In this situation, another method can be used, which is dithering with various amplitude and/or frequency. I've also tried that, and the low speed performance is still not great then.
I don't want to hijack this thread any further, as this is supposed to be about bachmann Geeps, not my decoder issues, so I'll post elsewhere once I've found the solution.
Thanks for your suggestions,
Koos
