FAMIS 31097

Looks like only things happening this past week are the FSS TPD signal is dropping, so the RefCav may need some alignment touchup soon, and the mysterious jumps in the TPD signal I first saw a couple weeks ago seem to have stopped as of last Tuesday. Looking at some IMC signals (final screenshot), these show the same behavior of calming down last Tuesday, however, I can't explain what would have changed that day to affect the feedback from the IMC to the FSS.
