Turning off the 9, 45, 118 MHz sidebands
We turned off the 9, 45 and 118 MHz sidebands at the rack beside the PSL enclosure.
This was to hopefully do OMC scans with no sidebands on at some time this week.
Attached are photos featuring Sheila and Georgia showing where to turn off the 9 and 45 MHz in the electronics rack on the opposite side of the PSL enclosure from the main entrance door.
You have to turn off these two amplifiers.
The second photo shows where to unplug the cable for the 118 MHz at the bottom of the rack.
