- 45: RADAR, Site RV Knorr, Mon 19-Mar-2007 01:24:21 GMT, Profiler lock up
The profiler locked up for about an hour (approx 0 - 1 UT).
It's not clear why, although I reset the parameters just beforehand
(I had widened the aliasing velocity and number of range gates Friday
evening for today storm).
Seems to be running okay now.
- 37: RADAR, Site RV Knorr, Sun 11-Mar-2007 22:35:51 GMT, Widened velocity aliasing
22:35UT Wind Profiler.
Strong winds and rain so the profiler was close to velocity aliasing at times
so decreased the coherent averaging so that the aliasing velocity increased
from 18 m/s to 23 m/s. Also increased the number of gates.
- 31: RADAR, Site RV Knorr, Wed 07-Mar-2007 03:04:12 GMT, RASS off during crew transfer
Turned RASS amp off while crew working on deck for crew change
(a small WHOI boat came along side to do the transfer).
- 26: RADAR, Site RV Knorr, Sat 03-Mar-2007 18:45:40 GMT, Repairs to RASS
While in port we found that RASS wasn't working. The acoustic part was ok,
but there wasn't anything showing up on the POP screen.
Swapped out the CI cards with the spare set and it start working okay.
Also reconnected aft port side speaker which had become disconnected.
Gary and Laura also added to the tie-downs for the speaker surrounds
because them moved around bit during the first voyage.
Also more tightly secured the profiler baffels.
- 18: RADAR, Site RV Knorr, Tue 13-Feb-2007 14:15:49 GMT, mysterious POP crash
Sometime around 13-feb-2007 04:30 UTC POP stopped working. I noticed the
following morning that the POP display was gone on the profiler PC. The
shipdat script was still running, so the problem wasn't a power loss. I
couldn't find any mention in the Windows event viewer of anything that might
be related to POP crashing. I restarted POP about 12 UTC.
- 17: RADAR, Site RV Knorr, Mon 12-Feb-2007 13:24:20 GMT, PROFILER
Yesterday about 2z noticed that the profiler and rass appeared to be greatly down in power. This seems to have started about 0z. As it was dark at this time I waited until this morning to get into the antenna surround. I checked all the rf connectors and cables all were fine.What I did find was the antenna twisted a few degrees off square.I trued it up and so far things appear to be better again. This may have to be checked every few days.Possibly some bad weather coming Wednesday do not suggest being in antenna surround in rough weather.

RASS was turned off again this morning, 6 EST, 11z, for the buoy recovery.
