[time-nuts] LPRO101 orientation vs lock

and will stay locked for about 45 minutes...."

I'm surprised that it locks in 45 seconds, I would expect it to take about 3-4 
minutes. All the units I have lock in 3-5 minutes if they are good, or longer if 
they are nearing end of life. The manual also specifies 3-4 minutes to lock. 

As to the heat sink, that may be a problem. Check to see that the baseplate 
temperature does not exceed 70 degrees C. This could be your problem. The 
manual states: "When thermal control is lost the result is a large rate of change 
of frequency versus temperature. As the baseplate temperature increases the 
unit will eventually lose lock."
