I'm fairly new working with the DCC system, and learning how it functions. I have a question in regards to setting up the voices of the conductor for the Athearn N Scale Challenger 4-6-6-4 Tsunami sound board. My locomotive is a 3985/11802 mfg in 2013. In my manual it shows the steam chart for function F6 which I tried and it does not work. I called Athearn and they have no idea, has anybody been able to get this to work. I'm using a NCE Power Cab for my control system. I would appreciate any help.
