  • 1700UT - Experiment started OK (Tiege)
  • 1711UT - Apparently only for one scan though, pps_delay1 value is all over the place (+ve ~2000000000). Setting off alarms. Auto-correlations look very bad. Restarting software on DBBC was not effective. Trying a power-cycle now. (Tiege)
  • 1733UT - Power-cycling DBBC unsuccessful, looks like even after fmset, times are still not synced up (though sync error goes away). Going to try rebooting mk5 for good measure. (Tiege)
  • 1740UT - This didn't work either, currently stumped. (Tiege)
  • 1750UT - reset hwclock on pcfsyg, and rebooted machine. Hasn't fixed issue. mk5 time seems to be consistent wit UT, but field system (and maybe DBBC) is off slightly. (Tiege)
  • 1800UT - fmset clocks being different seems to be unrelated, on second DBBC reboot, clocks now line up. However clkoff value is still far too high (by factor of 10000). It is definitely not a monitoring issue also, as webcam confirms high value, along with pps_delay being far too high. (Tiege)
  • 1815UT - Called Lucas, he could not figure out what was wrong with it. Seems more and more likely its a HW issue (Tiege)
  • 1830UT - Have contacted Yg on-site person, nothing looks out of the ordinary (but they are new). Getting them to manually power cycle the DBBC. (Tiege)
  • 1852UT - Still getting nonsense negative pps_delay and clkoff values. Going to stow dish and get Warren/Brett to take a look in the morning (Tiege)
