Hi Dr_C,
re the decoders I'll check to see what Rev it is.
 I haven't bought any for a long while since I started making my own, so it may not be the latest version.

Just had a look and surprisingly it's also Rev. G

That is puzzling - I wasn't aware of any firmware changes by Hornby during the rev G production lifetime. I wonder how it responds to analog? i.e. might it possibly have ICP? or could a hardware variation cause the difference you mention? Or perhaps I’m wrong and there were firmware changes?
