X-Band Sensitivity
Is there an easy way to replace the potentiometer on the X-Band Motion Sensor with a Digital Potentiometer.
I want to be able to adjust the sensitivity from within code.

From the schematics, it would appear that test point "TP" is connected to one pin of the potentiometer.
Is there an exposed via or something that can access the other pin?
Maybe Parallax could release a version that can be adjusted in software?
Thank you

I can see the pot but the pins aren't accesssible. One thought I had was to remove the pot with a pair of side cutters (hack at it) leaving the pins poking up from the board, and then solder to them. Wasn't sure how this would go though.
Any thoughts?
