Hi. This is my first post. I am installing a DCC decoder in an Acccucraft K28. I am using an LGB 55027 (I had it laying around), which provides 3 A to the motor and 1 A for functions. The model would not run at the default motor pulse (CV9) setting of 16K Hz. I also tried 2K Hz with no luck. It worked on 400 Hz. There are also lower frequency settings. Does anyone have experience with the optimal frequency setting for the pittman motors used in the K28 and similar locomotives? BTW the 16K Hz setting worked nicely on the Bachmann K27 using this same decoder.
