CER temperature has been higher by 5 degrees C than before since 11-27-2015 13:00 UTC-ish (right bottom in the attached). This is a day-ish later than when they started receiving air handler alarms. I notified Richard.

An interesting side effect of this is that I can now see that the output level of RF distribution amplifiers has a small temperature dependence. It's about -0.04dBm/K for 45MHz amplifier in CER (eyeballing right middle and right bottom).  This is picked up by the RF AM stabilization (left middle and middle bottom). Not that this is a bad thing in itself.

Also, diode room air conditioning stopped switching on and off repeatedly (middle top) at the same time the CER temperature went up. I notified Peter.
