I did a clinic at a lot of NMRA conventions up until about 5 years
        
        
          ago, entitled, "
        
        
          
            
              DCC-Ready? The Good, The Bad, and The UGLY!"
            
          
        
        
          In it, I dealt with the state of DCC-awareness at that time. On my
        
        
          website 
        
        
        
        
          ), I have a page
        
        
          about the subject. This page has a link to the presentation from
        
        
          my NMRA clinic, for a historical perspective. You may wish to
        
        
          detour there before going further in this column.
        
        
          First, let me state that things are getting better. A decade
        
        
          ago, the terminology was very confusing as manufacturers
        
        
          scrambled to be able to claim some level of DCC-awareness.
        
        
          Alas, many of these locos are still on the shelves, so the watch
        
        
          phrase is “caveat emptor" – buyer beware.
        
        
          
            Terminology
          
        
        
          I’m going to define what I feel are correct categories and then
        
        
          work forward with what is on the market to fit MY criteria. This
        
        
          is MY terminology, not some bureaucratic definition.

          DCC Impulses Column - 2
        
        
          
            DCC-Installed
          
        
        
          This means that there is a DCC decoder in the loco as it comes
        
        
          from the manufacturer. It may be a motor and light decoder; or
        
        
          a decoder for motor, lights and sound.
        
        
          Frequently, although the loco packaging sounds as if it features
        
        
          a name-brand decoder, that decoder may be a downgraded
        
        
          version. Some loco manufacturers order special decoders
        
        
          from the well-known sound decoder manufacturers, but with
        
        
          reduced features to reduce cost. Most times, the manufacturer
        
        
          won’t tell you about the downgrade on the box.
        
        
          Bucking that trend are the Blackstone (1) locomotives. Since
        
        
          they were designed by the folks at SoundTraxx, they have
        
        
          full featured Tsunami decoders in the models that are “DCC
        
        
          Installed” and the box clearly says “Tsunami Installed.”
        
        
          A prime example of the downgrade are the Bachmann locos
        
        
          sold in the 2010 timeframe that were marketed as having
        
        
          “Tsunami Technology”. Yes, the decoders were manufactured
        
        
          by SoundTraxx, using “Tsunami Technology” in terms of
        
        
          the sound recording quality. However, Bachmann asked
        
        
          SoundTraxx to work to a budget. That required a less expensive
        
        
          microprocessor and memory chip. Features were sacrificed on
        
        
          the alter of price. Some folks refer to them as “Pseudonamis”.
        
        
          I must, however, give credit to Bachmann. They didn’t say that
        
        
          they had Tsunamis in them. The box said that the locos had
        
        
          “DCC sound on-board”.
        
        
          “In the world of non-sound decoders, the
        
        
          manufacturers frequently don't spring for the
        
        
          top of the line decoder ...”
