Thanks both. Iain, I hear what you say Iain about specifics and I do know which decoder etc, but I think I am missing a convention here. When folks talk about a decoder reset is it usually to clear all the user variations back to as it came out of he box from say Bachmann, Intermountain , or does it mean completely erasing ell programmed data so that it needs to be re-blown? Thanks again
And I'm off to read LIJ's link more deeply.
