A new Ashtech CGRS (UZ-12) receiver has been installed on a powered splitter from the original antenna. The original TurboRogue receiver (PIE1) is also now tracking off the same splitter. Both receivers are using the original AOA chokering antenna. PIE1 data publishing is continuing as before. The TurboRogue is still using the H-Maser 5 MHz external frequency standard. The Ashtech UZ-12 is using its internal clock. There were a few outages (both in tracking and 5 MHz clock input) between about 16:00 - 23:00 UTC on June 23rd while this work was on-going. A new IGS log and notification will be sent when the PIE1 receiver change has been made final. We would like to acknowledge the help and assistance of the Pie Town VLBA Station personnel during this new installation and upgrade. Maintenance and operations of the PIE1 station is a collaborative effort supported by JPL, UNAVCO, and the NRAO Pie Town VLBA Station with funding provided by NASA's Earth Science Enterprise. Best regards, -Oivind Ruud
