Hi, I've been having a problem with the newer TTS decoders and spoke with the technical team at Hornby who are aware that the newer decoders were causing problems. They told me they have a solution and are about to release a fix that should resolve issues that have been reported. Basically, they can reprogramme the chip which should resolve the issue people are reporting between the newer and older versions. I suggest give them a call and you might be surprised to find your problem is like the ones being reported.
