Hi Guys and Gals,

Any idea what might be going on here? Almost looks like a sine wave on the screen. I tested the voltage at the board stack it's getting about +5vdc and +11.5vdc at the power header- I plan to convert to a switcher so I can get the full +12vdc reliably but I suspect power isn't the issue here.


Thanks, Ryan
