I have just made my first foray into DCC, and would appreciate some advice concerning a problem loco which is behaving erratically.
Over the last few weeks I have gathered together a DCC system (a Gaugemaster Prodigy Advance 2) and a selection of DCC fitted locos. Only just got round to putting it all together today.
The OO Bachman Class 20 (with sound) behaves perfectly, controllable down to a barely visible crawl, with no glitches of any description. The sound is also great fun.
The N gauge Peco Collett goods also behaves well, with the odd hesitation (maybe my N-gauge test track needs a clean).
However, the Bachman OO gauge 4MT 2-6-0 - which works perfectly on DC control (as do both the others) - is wildly erratic on DCC. When set in motion, it jerks to full speed, stops, jerks to full speed again etc. It seems to do exactly the same, at the same speed, whether I set the speed to 1 or 28 (max), and whether it is set for forward or reverse.
Obviously, the ultimate step would be to take it back to the retailer, but that's an hour drive each way (and I only went there yesterday to buy the Class 20, dammit). Since I am a complete novice at this, I just wonder if I have overlooked something really obvious. I have checked the obvious CVs and they all seem to be set to factory defaults.
Do I have a dud?
Thanks,
David
