So I grabbed a Prodigy Express a few weeks ago on eBay, and today my Atlas U25B came in the mail.
I tested it out on a piece of flex track w/ye old DC transformer and she crawls beautifully.
So, I figure I'll give setting up the Prodigy Express to the track a whirl, and see how it goes. As soon as I apply power to the track the lights come on and it makes a little hum. As I turn the throttle the pitch increases in steps: mmm-mmM-mMM-MMM, but not a budge in either direction.
I switch the wires to Prog Track, select the prog track with the cab, and set the address to 0003, just in case, and set the start voltage to 001. Power down, reset the wires to be Main Track, same song, different verse.
The loco says it comes with a DigiTrax DN146A decoder. I'm planning on replacing it with an MRC 1636 anyway, but I'm wondering what's actually going on, and if it indicates a problem with the Prodigy, with the decoder, or most likely of all is it PEBTAM (Problem Exists Between the Track and the Moron)?
I wasn't prepared for buzz or hum with DCC, the loco is pretty quiet on DC, but if this is normal it really makes me want to go with the sound decoders.
Any tips for the mentally impoverished here greatly appreciated.
