Tony,
Check to see if there is a RS / SS (Rail Sounds / Signal Sounds) switch under the tender. Place it in the RS position if there is one. I just can't recall for sure, but it "sounds" like it might be in SS mode. When you say there is no cab chatter, are you also missing the "back-ground" sounds??? Or are your referring to the cab chatter when you select Aux1 followed by #2?
Do you get the announcement sounds when you press Aux1 followed by #7? Do you get the chuff sound as the engine runs?
Given the age of similar engines, I sometimes find opening the tender and re-seating the boards corrects some problems.
Good luck.
