GunrunnerJohn,
Yes the DCC signal is essentially a square wave that has different pulse width's for encoding infomation onto the track. In my case the DC supply I use is set at 14VDC and then the driver boards chop it up with encoded data.
I certainly "see" where the DCS signal is not compatible. Just not sure if Legacy is or isn't. Maybe I'll find out. One catch with my "plan" I do not have a legacy loco! LOL
And again, the option of DCS & Legacy maybe my ultimate route.
I know one thing from years in electronics, NEVER let the blue smoke out of the components! You never can put it back in and have working results.
