FTS Report on DOY 154

I.  The following are clock offsets, in microseconds between the clocks
at each DSN complex and each complex relative to UTC(NIST).  The offset
is a mean of readings using several GPS space vehicles in common view.

II.  Frequency Offsets from linear least-squares fits on time-offsets
over the period (54975 to 54984):

III.  Comments:
* Values derived from linear least squares extrapolation or interpolation
% SPC 40 TTR5 receiver failed between DOYs 149 and 152 (MJDs 54980 and 54983).

NOTE:	As of DOY 135 (MJD 54966) SPC 10 data are from the newly installed multichannel receiver commonview with NIST. 
	As of DOY 68 (MJD 54899) data from (SPC40-SPC10) and (SPC60-SPC10) are derived from direct subtraction.
