Its right there under my name.

Lawrence, Kansas. Right outside of KansasCity.
Well heres the update. I just went back and tried the DSC with all of my receivers. Still it doesn't work with my XXtra, but it worked perfectly with both my R113F receiver and my XXL.
I don't get whats going on, but I guess the problem is with my brand new XXtra and not the DSC function.

Its not big enough a deal for me to send it in right now, I guess. But it is quite annoying that it isn't working.
