Howdy Folks, I have posted this on the Soundtraxx Yahoo group - thought I'd throw this at Y'all I have installed an ECO-100 into a N Scale Kato F7 (Actually a pair of them). I have used decoderpro to program them. I set the addresses, new horns, set the speed and set up the lighting. The issue I am having: everything works great --- except no sound. I have done a reset. Sound works great. Oh - I am a Digitrax user. I have the DCS200 (8 amp Super Chief) with a new DT-500 throttle. It won't read nor program these decoders. (I also have a programmer booster). So, what am I doing wrong-? Any and all assistance will be greatly appreciated. And - yes F8 is off. Thanks, Wolf
