Re: VCTCXO model and the issue with crystal aging - 2LO off the DAC range

On the DDS pcb - the position H10-V5 - you may find the pads for a smd pot trimmer (not populated), wired to the VC pin of the TCXO. They apparently planned to have a pot trim there in order to find a sweet spot for the voltage tuning range..
