	Bob, 

		FWIW, since aging would normally slow down with time, 
	this alarm is more of a "DAC is nearing limits."

		In Antonio's case he indicated to me off-list his DAC
	voltage is beyond 4.1V.  If anyone has any suggestions for
	re-tuning or replacing the OCXO, they might prove helpful to
	him.
