Henry asks experienced model railroaders for help:

“I have a new Atlas Gold U30C with QSI Revolution sound decoder. The Volume cannot be increased to the same level as other QSI locos. Atlas says that this series of U30C locos have these quieter decoders from QSI and they say that’s as far as they will go. This is even though the decoder is distorted and produces RF interference while operating. What are peoples thoughts on this subject?
