I looked at the available signals from the RF zones and couldn't find anything related to the instability. I noticed 240 Hz and 6 kHz component on the hall C BPM DAQ. I couldn't find anything correlated with this one either.
I suggested to OPS to unbypass 1L05-3 and bypass 1L10-2, if there is an opportunity. There was an observation made by Eric Deir about 1L10-2 forward power few days ago. I will keep looking for any if any rf related issues are contributing to beam instability

At the next opportunity, operators could swap these two DJ cards with spare 10A cards in MCC: (these have AB2 based trim card)
1. MDJ0L08V (NL01B04, Ch 24)
2. MDJ0L10V (NL01B04, Ch 30)

We're making it to the dumplette, but perhaps unsurprisingly the optics situation is far from ideal and the beam is a stripe on the Lamberton. Attempting to center it with the AT corrector lit up the IDXs even more, but this is not a rabbit hole we want to be diving into at the moment. Recirculated beam is making it to the dumplette.

Looked over RF signals and RF cavities in RF yesterday and today and staged a replacement RFCM at 0L03-1 (53 mW LOPW and varying) along with PTW. CC Adams diverted turning off beam for the replacement of the RFCM till possibly tomorrow or next week to see if it will mitigate the beam jitter on 1A and 2A viewers. I think this is a readback problem on the RF LOPW detector due to the fact that I don't see any variations in gradient or phase on any pertaining cavity signals or detectors and without proper 1427 Mhz signals, there would definitely be variations from the drive-line and cryo-module.
