==================================== r1849 ===================================== Ag : Series of problems described in email. No log yet. Ft : Observed with warm receiver (Scheduled as warm). Ke : FS crashed (23:55-05:25). Kv : Antenna problem (05:06-06:20). Yg : High winds (17:00-21:01). No problems found for : Ht, Ny, Wn, Wz ================================= r1849ag STOP ================================= 2018-07-03 19:01:58 R1849 finished at AGGO R1849 finished as scheduled. We started with FS 9.11.19 and finished with FS 9.11.6. We run the experiment on only one generator 1. During the experiment we had to face several problems. 17:00-21:05 Error messages occured in relation to the "vsi4" command. It disappeared when we discovered a loose connector of the MAT cable at the MOXA serial port multiplexer. When it was pushed in firmly, the errors disappeared. Apparently the command "vsi4=geo" did not cause an error, therefore it is assumed, that no data are lost during first 4 hours. However the decoding part did not work. 17:45 We restarted the FS in order to load the correct x.rxg and s.rxg files on the new FS-version 9.11.19. 18:04 We resynced the Mk5B+ recorder showing a red TVR-led on. After "s" in the ctrl-shift-T window, the led was off. 20:42 We restarted the FS version 9.11.6 in search of the "vsi4" problem and in order to load the matad.ctl with modified timeout for the decoder in search of resolving the error messages related to "vsi4". 22:00 An axis error occurred, antenna was stopped. Reasons are unknown, suspicion: overload of generator 1. Line 1078 lost. 22:40-23:08 Antenna power went off. Probably overheating of fuse. Lines 1197, 1214, 1231, 1248, 1265 lost. 04:20-06:40 Problem with time synchronisation of Mk5B+ due to a local network problem. The problem was gone by connecting the ntp-server to a different switch. Lines 2251, 2268,2285, 2302, 2319, 2336, 2353, 2370, 2387, 2404, 2421, 2438, 2455, 2472, 2489, 2506, 2523, 2540, 2557, 2574, 2591, 2608, 2625, 2642, 2659, 2676 lost. 07:30 Antenna error during source change. Reason unknown. 13:27 Automatic fuse of servos went off. Reason unknown. Lines 3917, 3934 lost. After having run several trials without such a number of problems prior to R1849, we consider AGGO being still in test phase. The experiences help us to become more reliable soon (I hope.). Saludos.

First scan out of wind stow 183-2107a Autostow SHOULD have been released (slightly) earlier, however was not. Required a “system reboot” in timeyg for autostow to be released. I initially tried these different methods (after halt, disk_record=off): source=stow,cont antenna=open, antenna=operate, cont “reboot drives” in timeyg, cont. This seems like a somewhat malevolent bug. So in summary, scans missed 183-1700 to 2101 Scan 183-2138a removed for SAR track (Lucas). ================================================================================
