I guess this is the equivalent of a keep-alive.
Which is less space intensive, keep-alive or LocoFi?
Any pluses or minuses on installation of keep-alive vs. LocoFi?
I seem to recall that a keep-alive is a problem in a LM-2S, but not a LM-3S. I think it may have had something to do with running on DCC. Anyway, is there any problem with the LocoFi using either a LM-2S or LM-3S?
