For what it’s worth, I’ve had 3 locos running with Loksound decoders for several years with no issues. This week I finally managed to fit a TTS decoder into a Hornby Railroad 9F. All seemed fine for several days, but yesterday, with no warning, the 9F , which was idling in a siding, suddenly took off at full speed and required swift “hand of God” intervention to prevent a major collision.
I have a Sprogg 3 controller. Seems unlikely that this was a coincidence, and that more likely the TTS is less tolerant of noise.
I do have it set to the default 03 address. I assumed that was ok since my other 3 locos have different addresses.
