VTMX: RADAR Messages: 20 Entries..

Generator change required all systems to be shut down.

All systems back up and running by 1PM local (19Z)

Ran vtmx2mode collecting time series and correlations
until 2324Z. (Sodar also running)

Switched to vtmx2mode only collecting correlations as 
per conversations with Bill Brown.

Tested the tape for files properly copied and it reported too many errors. Cleaned the tape drive and copied the files back into the /data/mapr/ directory and restarted the backup.

starting the 30 gate mode at 20:55 25 Oct 

Stopped the Praskov mode at 23:32, had a crash in the
middle.

From Charlie,
Yep, it looks like the Praskov configuration will generate
about 2 GB/hour. For the 40 gate mode, it is
2.3 GB/hour. For the 30 gate mode, it would be
1.7 GB/hour. All other computing in ATD will have
to stop while they analyze this.

I didn't see the problem with the schedule not
working. Your mode vtmxwind1 has 30 gates
and vtmxwind2 has 40 gates. Looking at
the tms files, I see the following:

24-oct  21_45    30 gates
24-oct  22_00    40
24-oct  22_15    40
24-oct  22_30    40
24-oct  22_45    40
24-oct  23_00    40
24-oct  23_15    40
24-oct  23_30    40
24-oct  23_45    40
25-oct  00_00    30
25-oct  00_15    30

So I think that the tms files show a two hour cycling of the mode. Maybe

the mode label in mapr display is not working.

I think they were looking for nci =66 for both test cases. It  looks
like
vtmxwind1 has nci=200.

The NCI is now changed.

RASS has been enabled for 25 minutes of wind and 5 minutes of RASS 
through the scheduler at 25 Oct 19:15. Using ARMISS to generate the 
sound and MAPR to collect the data.

RASS ran sucessfully for a few dwells and then crashed. Disabling
now at 20:46 25 oct.

NCI set to 200 for set one and it needs to be reset to 66, set 2
was set to 66..... Will rerun test for mode one again today, mode 
2 done.

Set the codes from 2 to 1 at 19:30 to run for an hour and then
look to see if the signal plot shows a middle line. Ending test at 
20:34 and looking at the signal plot. It does appear that the line
in the middle has dissapeared from the signal level time graph.

I have attached a cord from the sun-ws head phone jack to the 
audio amp and RASS should be ready to run.	

If there is no IOP I will start up Alex and Elenores data taking
experiment in the multimode format. I have replaced lo and hi 
with 1 and 2 for the 2 modes. If there is an IOP I still might
take an hour of the data.

Started the AE stuff at 21:18 24 Oct 2000, currently looks like
really good data from 700 m to 900 m. in the spectra. Holy shite,
every 15 minutes its collecting 555M in .tms files!!! holy bad 
dung!!!!

Stopped taking data because it is just to large. Stopped at 0:53

Min pulse width for the final amp is 200 ns or 10 counts.

PIRAQ has been run at 4 counts spacing w/o finding a problem
at this point.

addnl:
Alex grabbed me today and refined his request for
the mapr data that they would like. In particular,
he wants to oversample on the second test, so we
leave the xmit pulse at 100m, and set the gate width
as small as possible (here 12.5m)

We have never tested a 12.m gate width, so
don't be surprised if something funny seems to
happen - it would be related to the MAC
unit on piraq being switched that quickly.

Also, since the gate spacing is going to be so
fine, I would move the first gate up so
it is is in the region where we seem to
have been getting reasonable winds, say
600m. Otherwise most of their data will be
in that suspicious 100m-400m region.
One other thing - Alex requested that pulse coding
be turned off for this data - i.e. code = 1

Data backup of IOP7 starts at 0700 UTC

Started time series saving at 22:03 gmt

Radar pc had locked up at 1:18 local 10-19-2000
Rebooted at approx 3:20 local on the 19th
Had to do a reset on the computer to reboot it

Because there is a pretty solid line in the signal plots
at about the halfway point I have changed the PW to 50m and
the number of gates to 40. This should put the line at 1
km if it is related to the fact that the gates are split
in processing. SABL has a problem when it comes to 2 DSPs
in that they don't read exactly the same power level so they
produce some banding. The software written to the DSPs may
be perfect, but they might read a little dif and that makes
the line. 

The change happened at about 20:15 and will change back in a 
couple of hours. 

Data backup of IOP6 starts at 0700 UTC

Start vtmx2mode and time series collection at approximately 2300 UTC
and switch to vtmx at approximately 2320 UTC

Ended vtmx2mode and time series collection, started just vtmx
because the signal and SNR plots are confusing. Want to check 
signal level with extra amp in blue(3) channel. 

Backup started 15:17 UTC 17 Oct 00

It appears as though the lower gates are getting shifted to 
middle of the screen. Symetric spurs are in the middle gates.
Called Charlie and emailed Bill.

Data backup of IOP5, first tape, tape ends 0900UTC, also cleaned the 
exabyte tape drive.

The time series were forgotten till about 8pm LTC. 

TMS collection terminated at 17;26 GMT FOR MAPR. 

Back on for IOP 3 at 22:00 GMT
