0. Rich & Brett:
Ho receiver on-axis comment is confirmation of correct positioning
1. Issues from Ww
Real time etransfer to Bonn partially successful, Harro explained that there was a port conflict, try again next week
New power switch on gpib, not RS-232 yet
2. Issues from AuScope
Still working on Broadband receiver on 12m
Review of reported station issues:
3. Ww has new internet power switch to cylce GPIB when it fails
will replace GPIB controller with RS-232 connection
See above
4. Yg r4696
VNC connection lost for several hours, no monitor
(what about eRemoteControl?)
Report was VPN down (not VNC, but that was too), everything continued as normal at the site
Ww also has a VPN with VNC over it
5. Yg r1699
Monica restarted twice due to ifpic problems, not fixed?
operator talked to Jim about it, should have just restarted ifpic server
ifpic server needs to be updated
6. Yg says “wth” not found, fixed? (& in all sy= commands?)
Jamie fixed, there was an error with ampersand put in by mistake
all sy commands updated with ampersand
7. Ke r1699
S1-S4 high Tsys most of the time (120-170k)
example of operator report of high Tsys
RFI issue? yes, persistent and reported unevenly, but not too bad
DBBC problem? Tsys is high, but cal diode val might also be high
Ww core board replacement dropped SEFDs from 8000 to 4000
AuScope 3500 SEFDs so core boards probably okay there
> 8. Ho
RFI, overflows in S5, S6 most of the time
Radiolinks for wireless systems, also gets Hb
Consider new frequencies
Issues left over from last time:
9. 0.7 nanosecond clock jumps causing significant data loss during
analysis
Yg and Hb (and Ho): timing system or Maser PPS or PPS delay in DBBC
Rick ask analysts for times of jumps (we also percentage of loss)
NR maser still at Hb/Ho, but just used for frequency comparison
10. wind-stow progress, next test
next week firm up time for Wed/Thurs
apparent 'man in the middle attack' for pcfshb due to back-up
11. Brian agreed there is no need to move pcal to 26m
Okay
12. NTP configuration, need more servers, especially remote and
non-TAC/CNS
Ed contacted Hambly, plans to fix CNS clock firmware to include leap second approaching flag
NTP configurations need more servers, especially remote (6 or more) and not CNS clocks, but more local of any type is better too
Jim said okay to increasing server
13. “popen uptime” was added to all three AuScope 12m systems
Installed, waiting for a case where a machine is slowed down to be useful
14. Ed and Stuart to review status registers
Stuart will send documentation on Ww status registers for Ed to compare with other 12m antennas
15. Thanks for IPS/KVM/auto-login information
Thanks.
Can require a large load on UPS supplying IPS, but has two inputs
Brett/Stuart: Wireless switch can switch device from phone
“Pebble” unit, “Wemo” by Belkin
Telnet very handy, web interface can bog down
need more webcams for looking at equipment
16. Ho antcn reliability issues?
working on updating the antenna controller
17. Any luck getting spare VC parts? switch to DBBC at Ho?
Need some oscillator parts from Mike
now know what parts to ask for
DBBC has two CoMo/four AD2s so not quite compatible with IFs
will DBBC 105F support more than eight BBCs? Gino will know
