Hi. I'm relatively new to DCC. I had purchased a number of Atlas decoder equipped locomotives, including the Trainmaster, B 23-7's, SD 35's, and a U25B. These ran very quietly on regular DC power, but now that I've switched over to DCC, there is a loud buzz or hum from the motors when starting the loco, or when moving at really slow speeds. I have a LENZ SET 100, with the recommended DIgitrax power supply. Is there anything I can do to get rid of that noise. All of the factory DCC equipped locomotives do this,despite the fact that they were relatively silent and smooth operators on straight DC.
I have switched between the various speed steps and this has not helped.
Edit: I should add that these are N scale locomotives.
Thanks
