Hi folks.
Many people with the new Bachmann Berkshire have reported issues with slow speed running. Mine also had the "hitch" at slow speed that various folks have commented on, but I couldn't see a problem with the mechanism on mine binding in any way. So I decided to try to play with the BEMF CV values for the Tsunami decoder to see if that might help things. And it did. I wouldn't call my Berk "buttery smooth" at very slow speeds, but the "hitch" is largely gone. There is still a tiny bit of hesitation, but perhaps some additional break-in time will help that.
Here's what I changed:
CV's 213 and 214 set to "1".
CV 209 set to 15
CV 210 set to 240
Those of you running this loco on DCC and who are observing "ragged" running at slow speeds might try these CV changes to see if it will smooth out the slow speed running.
