Hi folks, I'm running the new Hornby Farewell Tour HST125 R3957 and the Hornby Centre 395 R3813 with the R8120 TTS Sound decoders. My set up is Hornby Railmaster via Elite and remote Select. The issue appears to be signal detection. On start up the decoder will run fine with sound and speed but might not respond to speed or sound changes for a few seconds or might not respond at all and require a hard stop and reset. I initially thought it was the 395 but now the 125 has the same issues. This can happen on Railmaster control or Elite. No problems with my other TTS decoders, A3, A4, Merchant Navy etc. Any thoughts?
