I am looking at buying the F7 A/B units, model numbers 63755 A and 63855 B, and do not see any specifications for the DCC decoder. What are the detail specs on it? How many functions, etc? Any brand name of the decoder? Thanks.
The "DCC On Board" decoder found in the F7 (and other non-sound Bachmann N scale locos) is proprietary Bachmann and has a very limited selection of functions and CV's.
