v041r 1999/031 Tid(JLauf) Hob(MEC/Dai?)
=====
Fringes found first go at 2040!

Tid:
152112 start: site power failure before start: lost 4h06m.
130nS delay difference between s and X !


V100f2 1999/072
======
Hob:
073/0016 TR #4 stopped, AT-3-000390/1e. Used 'transport 4 record'.

AT:
CA02 on Stn 21 throughout session
0749-0752 whopping RFI
0800-0802 more RFI

0823-500: 5.65Jy (2260)
0537-441: 2.62Jy
0407-658: 8.60Jy
0405-385: 2.10Jy (2260,2284)
2152-699 - CA01 LO correction is bad during the day:

HOB:
Pointing was stuffed for this whole session (by tests that left
Ceduna's pointing parameters in the system). Can see fringes on
most sources, but despite efforts of Richard D, data are essentially
uncalibratable.

V093f1 107/0600-2310 Pks(JER) AT(AKT,RHF) Tid(DLJ,JEJL) Hob(SJE?)
======

Tid:
Power failure earlier in the day, K-band stuck in ambient load:
had to reconfigure from cone. On source ~0820UT?
0537-441 boresights ~1.5md both axes
0820UT on source
0845UT 1144-379 0Ax, 1.5El

Pks:
H-maser playing up in the days before the run.
~1 turn of phase from temperature cycling in focus cabin.
Ran with 10kHz tone at bottom of band 1 to monitor phase.
1408: coherence went bad right before my military eyes:
checked H-maser: looked OK
1500-1546 off src to check: removed some bubble-wrap from Wiltrons,
1546-1610 coherence returned on 1921-293 scan
1610-1643 bad (non existent in fact) coherence on Circinus
1643-1725 more tests: removed all bubble-wrap, raised top Wiltron
clear to give 2~3" gap. No joy.
1735 breakthrough: checking 10MHz drive levels into Wiltrons
in control room, found bad BNC on sohrt patch into #31.
All OK now, except unlagged Wiltrons executing ~7 turns
of phase on every thermal cycle!


V093f2 108/0600-2030
======
TID:
0600 F1: no bandpass slope, but very lumpy and birdie-ridden.
0600 F2: ~1:4 bandpass slope, many birdies.

Pks:
Re-packed focus-cabin Wiltrons in bubble-wrap, upped A/C to ~26C and
left lift-leg door ajar.
0912, 1028, 1345 UT: focus-cabin A/C still kicking-in, with 3~4 turns
of phase each time (at 1345 anyhow)
1440: opened hatch and lift door in cabin; now stable at around 25C.

172930-173000 switched briefly to RCP

1600: high perrs on ATNF0281.5 : swapped to at06/6 OK

CAT:
0600: large "midband birdie" on alternate 5s cycles (00-05s), both F1,F2.

This is presumably the blanking pulse - didn't see this
when recorrelated A/Cs in June 2002 (with cycle 10 .0625 .02).
