| + | HOBART12 (Hb/H): Station experienced large clock drifts from start | ||
| + | of session to 303-2028. | ||
| + | |||
| + | Clock again drifted after approximately 303-0130, | ||
| + | continuing until DBBC reset at 304-0407. | ||
| + | |||
| + | Low fringe amplitudes in channel SR6U, | ||
| + | leading to occasional 'G' codes. | ||

| + | |||
| + | Other comments: a clock break in clock rates reported by the correlator for | ||
| + | HOBART12. The effect is visible only for the single band delays, no additional | ||
| + | break were added to the station. A small clock break is on YARRA12M baselines | ||
| + | at the X-band. | ||
