It depends on how old it is and when Athearn started making all r-t-r dcc ready. I have an A-B-B-A set of Athearn F-7s that were not dcc ready, but most of the newer r-t-r is dcc ready. I think the newest Athearn F-7 units are dcc ready, but I'm not sure. Athearn is very easy to convert to dcc regardless.
