The SQZ fiber beatnote has been dropping since the new box was installed this past Tuesday. It dropped below threshold and the autolocker turned off, but held lock. Sheila bumped this min dB to -14 for now, but we will talk with Fil about replacing that box soon since it doesn't look OK. See second attachment.
We then went out again from 2223-2254UTC to swap the TTFSS box. I reaccepted the old -12dBm value for the beat note min.

Unit S2300259 installed.
This only worked for about 3hrs before we dropped out of Observing again at ~2utc (7pmPDT). I lowered the RFmin from -12 to -20 to buy us some more time.
