The “throttle” knob on my MRC Prodigy Express handheld DCC controller has become relatively unresponsive. I sent one of my two back to MRC some time ago and it worked for awhile. The second one has the same issue now. It seems when I put downward pressure on the knob while turning it, it works a little better. Is there any way to adjust this feature? I sure miss the “old” Model Rectifier stuff made in NJ.
