AGC attenuators set at max for ifc (and ifd to a lesser extent) during setup, power levels above target and unstable. Band 14 and 15 in autocorrs looks bad (similar to X-band interference at Hobart). Have tried adding more attenuation to the IF chain but it doesn't seem to be helping bring power levels down. dbbcreset command also does not help. Restarted DBBC machine, nothing changed. I think it may just be the result of local RFI on site? Will mention it to Warren tomorrow.

  • 1830UT - Experiment started OK (Tiege)
  • 2130UT - Power levels seem to have mostly stabilised for ifc and ifd. AGC no longer maxed out. Band 14 and 15 in autocorrs still look trash though. (Tiege)
  • 04:45 UT reset dbbc gains (warren)
  • 05:30 UT Created New eRemote Log File (added .txt extension) as Log Monitor malfunctioned. (Earl)
