I believe it just looks for messages from the NMEA serial port on the GPSDO.

Also, you can select different clock sources when you instantiate a UHD 
source/sink block in GRC.  There's a drop-down menu.

If you aren't programming using GRC, you can use what it *does* generate 
in the Python as a template for your own code.
