Hi Fellow Hobbyists - I just completed a 5XL sound decoder installation into an LGB 28002 Rugen Steamer along with a Massoth Pulsed Smoker. Everything works great except I notice a slight motor hum noise when I operate the loco on my test stand when the the sound is off. I set the Motor Control for Linear and Buhler/Kiss Motors which has worked well for all the other 5XL installs I've done on LGB locomotives. I tried turning off the Load Control/EMF but then the motor won't operate so that's not an option to eliminate the motor hum noise. What other options should I try to remove the motor hum noise?
