Q330 acting as master for the underground GPS timing system.  Not a seismic station!  The GPS signal is passed through two splitters here to be sent underground to Ross and Yates, so 3 total GPS transceivers are used here.

| 09/21/2014  | Set up Q330 in server room and connected it to the GPS antenna on the roof of the Yates admin building.                                  | Tanner     |
| 11/20/2014  | Started sending the GPS signal underground via fiber.  | Tanner     |
| 01/12/2015  | Moved digitizer from its original shelf to a new shelf in a server rack. Installed a new GPS cable which converts the signal going from the digitizer to the GPS transceiver from RS-232 to TTL.                  | Tanner     |
