The attached are 0.01Hz BW spectra of the BSC ISI's CPSs from this morning. This is looking for elevated noise floor. See logs 25713 & 25820 for an especially bad noise floor on the CPS noting the Stage 1 and Stage2 sensors have different scales and therefore noise floors.
While these are not as bad as the ETMY in the above linked logs from back in Feb/March; some are higher than their fellow sensors and maybe should be watched closely. They may need to have their cards cleaned up. The units of note are:
ETMX Stage1 V1; ITMX Stage2 H3; ITMY Stage2 V3.
ITMY also has another notable feature: A broad hump at 59Hz on Stage2 Corner2 H2 and V2 sensors.
There are other features evident, mainly narrow lines of varying heights and frequencies. First things first.

The 59Hz hump on the ITMY Stage2 Corner2 sensors was at 90hz a week ago and steadily marched down to 59. It probably isn't doing too much harm at the moment but if it doesn't stop coming down... It might be interesting to see how far it goes but I think this needs action. A power cycle of the satellite rack is a good start. This will happen in a couple days anyway...
