Right after the swap the new ASHTECH UZ-12 receiver was running off its INTERNAL clock (not the H-Maser) for the first two days. This is reflected in sections 6.4-6.5 in the updated log, but is repeated here for your convenience: 6.4 Standard Type : INTERNAL Input Frequency : (if external) Effective Dates : 2004-11-25/2004-11-26 Notes : Internal clock used after reciever swap. : Actual start date 2004-11-25T02:30Z : Actual end date 2004-11-26T21:30Z 6.5 Standard Type : H-MASER Input Frequency : 5 Mhz Effective Dates : 2004-11-27/CCYY-MM-DD Notes : Actual start date 2004-11-26T22:30Z This data has also been made public. The new ASHTECH UZ-12 receiver was again running off the EXTERNAL H-Maser starting on 2004-11-26T22:30Z. We apologize for the inconvenience this may cause. Maintenance and operations of the FAIR station is a collaborative effort supported by JPL, UNAVCO, and Gilmore Creek Observatory (NOAA), with funding provided by NASA's Earth Science Enterprise.
