Tsunami decoder
Okay, a quick update. I've arrived back home and got busy installing a Tsunami TSU-1000 decoder in my Athearn C44-9W, the one I am superdetailing. While the detailing project is not finished yet, I wanted to see if I could get the decoder and speaker in properly. That worked out fine, and I now have my first sound equipped loco on the layout. :-) It did take a little time to get the speed response of the loco to work nice, it's an older loco, with an older Athearn motor, not exactly known for their superior running characteristics, but a bit of tweaking (thanks to some tips from fellow model railroaders) of the BEMF settings worked a treat. BEMF in the Tsunami is configured by CVs 209,210, 212, 213, and 214. They all work in concert together to control various parameters in the BEMF control. If you're not sure I recommend to download the 'Diesel Users Guide' from the Soundtraxx website, and look on page 48, they have some tips on adjusting the BEMF settings. It's a trial and error process, and if you can program in ops mode with your DCC system it will go a whole lot quicker.
