More cables with pin 19 missing
When testing the demod concentrator readbacks at HAM6 we found more DB37 cables with unconnected pin 19. Unfortunately, this leavs the common mode potential undefined.
The RF/LO mon readbacks are all properly connected. PowerOK readback on the LSC demods does not seem to be working -- possibily because we are missing GND pin 19?
