DC Offset vs temperature

Hi all, Thomas has discovered that DC offset calibration for LMS is drifting a lot with temperature changes and this has detrimental effect on the modulation accuracy: http://code.google.com/p/umtrx/issues/detail?id=31 One solution proposed by Sylvain is to tune modulation a bit higher using digital modulation, which should be straightforward with UHD which has digital mixer in FPGA. But I wonder what is a recommended solution for this temperature compensation for LMS in general. Srdjan, could you comment on this? -- Regards, Alexander Chemeris.
