13:00 UT Kjell changed the VPol optical transmitter in Ant 10 on Tuesday (Oct 3), and I finally had time to check it. I find that it solved the problem of the rapid fluctuations we had been seeing for some time (present at least since the Sep. 10 X-flare, but possibly well before. However, the levels for Ant10 VPol were low, so I have updated both the FEM and DCM level settings (for all antennas), which I hope will solve the problem. All gain/attenuation calibrations will now be different for data after this time, although it should all be handled automatically.
