Not that close to a sine wave, that's why I recommend the switch. Those vertical edges play havoc with the DCS carrier.

As GRJ says, it's those pesky vertical edges. To wit, while I haven't seen anything "official" from MTH, it has been reported that the "best" track power waveform type for DCS is plain-old DC which of course is a flat-line and as benign as they come.
