Joe asks readers for their opinion:

“I have a mth SD70ACE and I am using a digitrax DSC50. The problem is I can not get the ho dcc couplings to work. All other functions work. mth use’s sound pro3.0. and I can’t find any cv.s on that sound system. I would really like to use them. I hope some one can help me.”
