I just checked calibration of my setup - at the moment, the counter 
(calibrated against a 10 MHz Z3801 GPS DO) shows I'm within a Hz. 
However...I know exactly what happened.

Yesterday it was around 50 deg F here and the temp inside the house got 
up to around 75 deg F.  This was warm, so I turned on the air 
conditioning after lunch.  When I went to bed, I did not turn the system 
over to heat.  So the temp in the house plummeted last night until about 
3 am local time this morning, when I turned on the heat.

This reinforces my need to get going on my AMRAD-type converter that 
uses the 3 MHz OCXO.

thanks much and 73,
ben, kd5byb
