Can you specify what pot you have used? I am using some for my TCXO boards and am not quite happy with the settability or mechanical stability. resulting in noise and higher Allan Deviation.
A low noise regulator driving it also helped. I subscribe to the opinion to not use any extra resistors. When the pot is used as a voltage divider, theoretically it should have the same TC throughout, so temperature effects should not affect the divide ratio or the output. Only the input impedance of the control voltage input to the oscillator relative to the effective resistance of the pot will provide some effect with temperature.
