Sounds good. I allowed for up to 2.6 V output (+18 dBm) and my slope is 0.0998.
A guess might be that you are near the noise floor, especially with the detector circuit not in a box yet.
That definitely doesn't sound right. I also use a DDS-60 board and my output is a good looking sinusoid.
The manual for the DDS-60 says supply voltage can be 8 to 16 VDC, so you are in the right range.
