When both PZT paths for the FSS boxes are plugged in, we see 5 MHz sidebands on our transmission beatnote.  When either path is unplugged from the laser PZT, the 5 MHz sidebands go away.  This is weird because the PZT shouldn't be that fast...

We also have sidebands around 430 kHz.  We opened the loop to the lasers and still see this modulation on DC...

Tried grounding all power supplies together to avoid ground loops.  Found out that our negative high voltage supply was shorted to ground.  Spent day making new cords.  Will test tomorrow.
