"IMHO ALL Command systems should be DCC compatible."
There's something we do agree on!
Wish I would have found out how compatible DCC was years ago! Lucky for me my Loco roster is only 30 units and 6 are converted to Tsunami 2 4400's so far. It was cheaper to go with the Soundtrax decoders than to install the ERR TMCC, which is far, far, lower in sound and control quality and more complicated to install.
