Body: 

-Replaced aging cables in 0L04 from patch panel to FCCs in all 8 cavities and secured internal connections in the 0L04-2 FCC to hopefully stabilize GASK.
-Verified output of 2.5 W amp and refitted cables on 1L17-4 RFCM. Cavity recovered and optimized RFCM.
-Confirmed 2L13-2 needs an RFCM replacement, but wasn't able to get to it today.

Checked terminals on the DC output cable for tightness for MQK5R09. Each terminal was able to be tightened by about a quarter turn. The supply was turned over to ops following the inspection.

DC Power will continue to monitor to see if the noise returns.
