re aLog 26140
Here are snaps of 0-120hz spectra for HAMs 2 thru 6 with the reference traces from 13 March (before the switch last week,) and the current traces from this morning at 3am. Not even really suttle differences so I'd say at least no harm done from the switch to the common timing source.
Here are photos of the HAM CPS Satellite racks which have been mounted onto the BoxBeam Mount. This is why the HAM switch over was much longer than the BSCs. The single port Power Regulator board was swapped for a dual on the primary (CPS1) rack. All grounding was made more robust for both the primary green ground wire and the probe cable shield (woven copper jacket.) Mounting the racks on the Box Mount and rerouting cables such that the racks could be accessed but are more out of the way or could be moved when needed for safety, such as slinging heavy wrenches around when removing a door.
The photos are in order, HAM2 Rack1, Rack2, HAM3 Rack1....HAM6 Rack2.
@DetChar: Can you watch HAM3 for the next few days, and see if this has had any effect on 0.6 Hz?
