Thanks for your reply, I shall make the purchase. Sadly after posting yesterday I must have got carried away, running the loco with the NCE power cab. In attempting to locate the "chuff function" F17 I must have done something really stupid, change some CV settings, and now my P/c won't read the decoder at all. I tried the CV2, then entered the number 8. it prompts me for a value but then when I enter 8 it just reverts to asking me for a number, rather than reading the Hornby code 48 which would allow me to reset it. All of which is to say, that so far the sounds are Ok, whether they are accurate I am not expert enough to say, but the decoder seemed like the nearest match of those available. As regards the quality of sound one or two (coal shovelling) sound a bit "tinny" but I have no point for comparison, and as I said, being my first foray into DCC, it's so much more exciting than analogue that I am not past the first wave of excitement! (Except now that it has stopped working!). Steep learning curve, but thanks for your advice.
