====== R4650 ====== {{tag>}} ~~DISCUSSION~~ hb: recording to HOB+0119 start at 8692 GB. ke: *recording to BKG+0126 start 0 GB. Test record OK. *After start channels 11, 12 looked suspect in autocorrelation. * clock jumped at 19:00. halted schedule and reconfigured dbbc at 19:03. fs crashed also. * one missed scan 240-1902a. next good scan 240-1916. (missed scan record stop means -20 GB approx.) *clock delay drifted from -0.29 us to -0.4 us around 240/20:30 and has stabilised see ke_ddiff.txt plot * missed scans 240-2312 and 240-2328 due to dbbc reconfig. * clock delay stable since 240-2330 (as of 240-0315) At UT13:40 day 241, the delay difference at Katherine started to drift quite badly, had to run fmset at 13.53UT (Imogen) For some reason, gnuplot will not plot values of ke_ddif.txt past ~11:00UT - not sure why (Imogen). At 14:29UT, restarted DBBC as clock drift was still occurring, ran fmset to resync dbbc and mark5. Delay seems to be stable as of 14:42UT, however cannot plot the values as they do not seem to be reaching the ke_ddif.txt file. yg: *recording to USN-0019 start 0 GB *spurious wind stow 240/21:22, antenna will not release elevation brake. Sending Jack from moblas to try handbox antenna alive *also note anemometer cant connect to device *schedule halted 240/21:36 *drives still inoperable at 240/23:59 *restarted for scan 241-0447
